Kinds of Centrifugal Pumps Found In HVAC Systems

HVAC SystemThe most commonly used pump in HVAC systems is a centrifugal pump. Centrifugal pumps are mainly comprised of a motor shaft connected to a pump impeller. It works by creating a pressure difference between its water outlet and inlet. This enables water to move through your HVAC pipes.

Here are some of the most common types of centrifugal pumps for your HVAC system:

Circulating Pumps

Circulating centrifugal pumps are mostly found in low capacity and low-pressure systems. Your HVAC’s capacity should be below 550 lpm with an operating pressure of below 860 kPa. A circulating pump is supported and directly mounted in the HVAC’s piping system. Its motor is available in horizontal and vertical positions.

End Suction Pumps

These are pumps with a single suction that can be either flexible or close-coupled. Water enters your pump horizontally from its suction end and vertically exits from the top of the pump. This pump is the ideal choice for HVAC systems that has 45m of head and up to 15,000 lpm of capacity. All its components including the bearing assembly, pump and motor are mounted on one base.

Split Case Pumps

Split-case centrifugal pumps have flexible coupling between the pump and motor. The assembly is mounted on a common base with the pump’s discharge and suction in a horizontal direction perpendicular to your pump’s shaft. They can either be double or single suction. They may also come with multiple impellers to increase the available head in a single pump. These pumps have a capacity of 24, 500 lpm with a head of 180m and can handle up to an operating pressure of 2700 kPa.

Vertical in-line pumps are double or single suction close coupled pumps. They are usually supported by and mounted on the HVAC’s piping system. They have a 94,000 lpm capacity with a head of 90m.

The pump is a critical component of your HVAC system. Make sure the system works smoothly by having an expert handle your pump’s installation, repair and maintenance.

Understanding the Concept of Big Data Management

Man pointing to the big data management informationBig data management involves the proper and strategic organization of data derived from internal processes, as well as external processes and relationships with vendors and customers. These sets of data are often analyzed to support a company’s business intelligence efforts, although government agencies also require big data management to ensure the safety and welfare of citizens.

The concept of big data has evolved substantially in recent years as various industries deal with an overwhelming rise in technologies, data volume, and scalability. As a result, companies are facing a challenge in finding ways to interpret data accurately that can support their business growth in the mid- and long-term.

Making Business Decisions

According to a study by data verification vendor Experian Data Quality, the impact of unsound data management strategies are astounding. It discovered that only 44 percent of companies trust their own data in “making big business decisions,” leading to a 51-percent decline in overall customer satisfaction. On the other hand, 60 to 80 percent of companies with a successful data management initiative report increased revenues.

The task of managing big data depends on data scientists, database administrators, chief data or information officers, and business analysts. Organizations can also get tech companies such as Cloud Xtension to provide them with outsourced IT development for big data, should they lack resources to implement big data management themselves or hire an in-house specialist to do it for them. Hiring a third-party big data management provider is also critical for organizations that want an unbiased look at their data.

Reducing Data Footprint

Simplifying data sets and incorporating virtualization technology saves companies costs. The latter involves reducing data footprint and focuses on being able to store and pull up data easily by minimizing its footprint. The costs saved through this could otherwise be used for daily operations and to increase your IT staff’s productivity.

Big data management will continue to present new and welcome challenges to organizations in upcoming years. However, it will not be as daunting as it appears to be with the right strategies in place.

Traditional Phone vs. VoIP System: What’s the Best for Your Business?

Man pointing to the VOIP informationAs a small or medium-sized business, you need to have an easy and hassle-free way of communicating with your clients and vice versa. At this point, you may think that you just need a traditional phone system, like the one you have at home. It is not as easy as you think, however. Choosing the right communication platform for your business can be quite tricky, seeing that you have some variables to consider.

Ultimately, you have two primary options: the traditional phone and the Voice over Internet Protocol (VoIP) system. Knowing more about how their differences can help you make the right choice.

The hardware

Although traditional phone systems have improved considerably over the years, they still require the installation of bulky and heavy equipment. The physical lines and devices that comprise them need not just a lot of space on-site, but regular maintenance too. All these further increase the cost to operate them.

With VoIP, on the other hand, the entire system already serves as the phone switch. For instance, when you work with a highly reputable Asterisk provider, you can transform a single computer to a complete and robust communications’ server. So just imagine how little space you have to use when you go with VoIP.

The initial cost

Installing a traditional phone system in today’s time and age costs a lot more than when you set up VoIP. With a cost per employee ranging from $800 to $1,000, this can quickly balloon to proportions you may not afford. Therefore, if you have five employees, all of whom requires a line, you are looking at a $4,000 to $5,000 initial expense.

Opt for VoIP instead, and for the same number of employees, you can reduce your costs by more than half. On average, a VoIP system with five extensions only costs about $2,000.

Although the final decision still depends on your preference and needs, you should not disregard all the benefits and advantages that VoIP has to offer.

Eliminating Location Problems: The Importance of Telehealth

Doctor using telehealth software for her clientGetting proper healthcare in some locations is a very difficult dilemma. This is especially true in remote areas where it is not only inconvenient to travel to the nearest hospital (which might be hours away). It might also be quite expensive because of travel costs. Fortunately, patients no longer have to go through such difficulties because of the technological advancements in the medical telecommunications’ technology.

Here are four benefits of using telehealth software systems.

Convenience

People with mobility issues know how difficult it is to have to go to the clinic or hospital and wait in line just to see a doctor for routine or follow-through checkups. Telehealth allows these individuals to have their checkups in the comforts of their home or in the nearest facility with a telehealth system installed.

Secure Healthcare Access

Timely and accurate diagnosis of a health issue could mean the life or death for certain people. The earlier a patient gets diagnosed, the better chances they have at undergoing treatment. This, in turn, means higher chances of survival and recovery. However, those living in remote or rural areas might not have the same opportunities. That doesn’t mean, though, that they can never have easy access to healthcare. A telehealth software is one way of solving this location issue. The patients can be diagnosed and treated anytime without the delay of hours of travel.

Lesser Expenses

Aside from the money you save in travel expenses, telehealth offers other ways of lowering healthcare costs. Telehealth technologies have proven to reduce costs of healthcare while increasing efficiency through shared staffing of healthcare professionals and better management of disorders and diseases. It also eliminates the need for extended stays at the hospital.

Telehealth is a very important piece of technology because it allows rural communities a chance to experience state-of-the-art and quality healthcare. They don’t need to buy new equipment or employ the local healthcare professionals. Doctors can now tend to patients even if they are not able to physically reach them. Virtual healthcare services save both the doctor and the patient precious time and effort. They can exchange medical information without having to see each other face to face.

Effective Ways to Make Your Cloud Service Reliable

man interacting with cloud service applicationsOne of the recent innovations in technology is the Cloud storage service, or simply “The Cloud.” In this service, subscribers or customers store all kinds of data — pictures, music, and other multimedia files. They also use the wireless storage service for other types of files, such as confidential office documents. That is why it is essential for the Cloud service to be always updated in terms of security and other features. There are many ways in keeping your Cloud service top-notch. Here are some:

Optimizing the Performance of the Service

As many people now use the Cloud for storing files, it is important to keep the performance of the service optimized for the best user experience possible. For the optimization, tools are currently available on the market to ensure the quality of the service. These tools will analyze all data related to the service, including the number of users, the server status, and the maintenance costs.

Testing the Optimization

Once the service is optimized, performing cloud performance testing through an internal alpha release of the update should take place so that any errors in the code or other errors in the user experience and performance may be addressed before the update may be released to the customers. In this manner, your team can discuss and act on any mishaps beforehand. This is one more way to make sure that the service is already top-notch.

Any service given to users or customers should always be tested and the performance optimized to make sure they’re always happy with the service. In the industry of Cloud computing, though, it is of utmost importance to give the best security and user experience to protect confidential and personal files and documents. Remember: Optimizing and testing performance is necessary.

Employee Off Boarding Tips: Safeguard Your Company Data

Man showing the personal data protectionIn a perfect world, employees leave your organization under amicable conditions. Your employee on-boarding process is simple and efficient, leading to very few wrong hires. The reality, however, is that some employees might leave your organization under hostile circumstances, which then leaves your organization’s sensitive data hanging in the balance. So how do you safeguard this sensitive data?

Make Sure You Have a Process

This process should ideally be easy enough to implement as soon as you begin your employee off boarding process. You should create a specific process for safeguarding your data with help from your IT department.

Disable All User Accounts

Shut down all network access and user workstations, change access passwords to phone systems and cloud storage, as well as access to business application lines. You might want to disable accounts of change passwords until you could reassign the access lines and workstation to a new employee.

Disable Access to Data Everywhere

As early as the employee on-boarding process, you must make it clear that all data your employees have access to, along with devices they use for work is company property. First off, all your employees must have signed a contract agreeing to the remote-wipe of their company devices if they leave your company and take a company device with them. This also applies to all email accounts. With a remote wipe, even your employees’ data might be lost, so you must encourage them to be honest if they want to leave the company or risk losing their data, along with your company data.

Adjusting the Workflow

Depending on the specific circumstances of the employee off boarding, the position your ex-employee left behind would likely be absorbed by someone in the company or taken over by a new hire. You must have a plan for redirecting emails for the vacated position. You must also tell your IT department to audit licenses for business application lines, company software and cloud services to make certain that they won’t be paying for extra licenses they don’t need.

It doesn’t matter if your company experiences little to no turnovers; it is your responsibility to safeguard not only your company data but those of your clients as well. Having a streamlined approach for managing this situation will come a long way in making certain that you are consistently protecting your clients and your company.

Why Planners Want Your Convention & Visitors Bureau to Have an App

Man using the CVB appMost CVB’s all over the country are still using traditional ways to market, meet and work with planners. While there are many highly capable people operating CVB’s, many planners are typically frustrated because of the limitations of the traditional ways of doing business.

You can have a convention and visitors bureau application like Visit Widget customized for your organization, instead of relying solely on traditional systems. The right CVB app can make things go easier and smoother for your organization, and planners will enjoy working with you, as they experience these benefits.

Fewer time-wasting meetings

Particularly if your planner is representing a company from an area hundreds of miles away, it is highly inconvenient for the planner to fly to you and vice versa. It takes up too much time and resources. There is also the question of risks. Meetings in themselves are great time-wasters. You probably have to talk about the weather even before you can get down to business. As for telephone calls, if the planner calls you while you are not in the office, you may have to waste more time trying to pull up the information they need or to relay what they need to someone in the office.

With an app, it doesn’t matter where you are or where the planner is. It doesn’t even matter what time it is. You don’t need a time-wasting meeting. The planner can monitor your activity in relation to their requests, which they can make at any time.

Faster application of changes

Planners, or the organization they work for, will change their mind about something all the time. It’s part of the business. And those working in the CVB are left to scramble to effect those changes. Whether it’s a change in the number of seats in the venue or a new request for additional hors d’oeuvres, an app can take the information instantly and can also update the planner once you have made the changes they want.

A CVB app is not just an app for the sake of being up-to-date; it’s an app that does a stellar job of making things easier for your organization and your clients. You can stick with conventional systems and waste resources, or spend on an app to help you improve your services and effectiveness.

SIP Trunking Benefits for Consumers

Man pointing to the voice over internet protocolOver the years, one of the most important changes in the world of telecommunications happened right before your eyes. Now, many businesses shifted their communication services to Session Initiation Protocol (SIP) trunking to take advantage of the various benefits it provides.

While there is stable revenue for you as a reseller of wholesale SIP trunking services, you have to consider the benefits that it offers to customers. You deserve only the best service and value for your money. Here are the essential advantages that you will get from SIP trunking.

It is flexible

You usually do not anticipate your future needs when getting a plan for traditional phone lines, because these old PBX lines do not offer you much flexibility. With a SIP trunk, you can get the flexibility you want, such as the capability to add an on-demand feature when you need it.

You can add additional trunks, more call minutes and more channels, among others.

Perfect combination

With the use of SIP trunking, you can get rid of keeping both your data and telephone networks by combining the two in one service. And it gives you integrated communication elements including conferencing, video, screen sharing, instant messaging, and more. As a result, you have a perfect combination

Connected Virtually

For your traditional phone lines, the Primary Rate Interface (PRI) needs the circuits to be connected physically to the Public Switch Telephone Network (PSTN) using cables and costly termination hardware.

Since your SIP trunks connect virtually, you can avoid those expenses and save time because you do not need cables.

Low Costs

If you choose SIP, you can save so much money of up to 60% of your communication expenses by getting away with the costly PRI lines and multiple charges for long distances. You can get the benefit of a fixed monthly bill and pay what you currently need. In other words, you pay two for the price of one.

Whether you are a reseller or a customer, SIP trunking promises various benefits for you and your business.

Protect Your Business from Data Theft

Man doing IT security informationAll businesses need to implement powerful protocols when it comes to protecting data. Metropolitan Networks relates that companies need to comply with guidelines and regulations to maintain safety for their data—100%. This pertains to all aspects in dealing with information, from development to storage to sharing. The appropriate security program can identify any risk and enable you to act quickly.

What does a security program involve?

Audit the System

Before your company implements any security protocol, know first about your system’s weaknesses. A thorough audit will identify vulnerabilities that help you invest in effective security solutions.

Stop Unauthorised Access

Your business needs to have a firewall. The network security system controls traffic flow to an untrusted source and a trusted source, granting or rejecting access. Installation, monitoring and support of firewalls should be done by a vetted firm.

Make Sure Employees Follow Corporate Security Policies

In today’s time where hacking and data theft run rampant, it is risky to rely on the infrastructure of your IT system alone. Your employees can become vulnerable and leave your entire system open to attacks or infiltration.

Your employees, therefore, should receive training and guidance when dealing with particularly suspicious emails. You should also monitor and control the use of external hard drives in the office. Your business should further implement a stringent authentication process for signing in.

How Cybercrime Starts

Cybercrime typically begins with a seemingly normal email message that contains malware. Once opened, the malware will infiltrate the network, giving the attacker numerous opportunities to steal data and other crimes. In addition to data theft, cyber criminals can even shut down the entire network, causing massive financial losses.

So before criminals can even have a chance to infiltrate, get rid of such opportunities. Enlist the high quality services and products of a cyber-security firm and follow a proper security program.

3 Qualities of Effective Cloud Performance Testing Tools

Cloud service applicationSoftware developers and testers are often lulled into a phony sense of software security. For example, software performance and features might satisfy the expectations during the production time, but crash when introduced to the end users. Studies show that many organizations conduct performance testing known as load testing without effectively emulating the real-world scenarios encountered by the end users. When realism is overlooked in load testing, a plethora of performance issues surface.

Cloud technology offers important features that provide testing teams with superior models that can capture realistic behaviors of software before distribution. Cloud-based testing also increases flexibility and lowers ownership cost. But before choosing cloud performance testing tools, it is important to consider their integration with cloud environments, their ability to perform realistic tests, and their support for web technologies.

Integration with Cloud Environment

The manner in which performance testing tools integrate with the cloud environment is an important consideration. Using tools that are not easily integrated with cloud platforms will result in conducting several processes manually, such as learning how each of the platforms works, as well building, accessing, and maintaining the machines to be used. According to experts, cloud performance testing tools must integrate with the cloud to accelerate and simplify the processes required to be employed in the cloud infrastructure.

Realistic Tests

Cloud-based testing is more realistic compared to laboratory testing. However, moving to the cloud infrastructure does not guarantee realistic tests. It is, therefore, necessary to consider bandwidth challenges experienced by end users by virtualizing networks and making parallel tests. In virtualizing networks, you must consider limited bandwidth and packet and latency loss. Cloud-based performance testing tools should be able to parallelize requests in order to produce realistic results.

Support Web Technologies

Many businesses prefer tools with built-in support for web technologies, such as WebSocket, Microsoft Silverlight, or AJAX. Otherwise, effective testing of performance of such applications will be impossible.

Cloud technologies offer organizations a mechanism of improving the realism and scale of load testing while at the same time lowering ownership cost and saving time. In order to address the challenges in software performance, it is best to embrace cloud-based testing. Simply moving to the cloud infrastructure is not sufficient, but the type of tool selected and how well it supports cloud technologies determine success.
