Consider a VFD to Lower Your Energy Costs

Posted by IER Services on Feb 25, 2018 2:21:14 PM

Variable frequency drives are also called frequency inverters and AC drives.  These are  electric devices used  to change the utility power source to variable frequency to control an AC motor in variable speed operation.  

This adjusts the speed of an HVAC fan,  pump motor or commercial electric motor based on demand. This will help lower your energy costs while also extending the life of the commercial & industrial motor and the mechanical components.

A  HVAC fan or pump motor is either on or off.  There is no in between.  Add a VFD and you will eliminate the initial power surge and mechanical shock when the motor is switched on.

The Basics About Water Booster Pumps

Posted by IER Services on Feb 12, 2018 11:18:53 AM

There are many reasons for low water pressure: buildings above the water supply lines, gravity, and commercial buildings that are tall and require additional water pressure to serve upper floors. (On current new construction and retrofit projects, water pressure booster pumps are used to provide adequate water pressure to upper floors of high rise projects.)   water booster pump.jpg

Considering a Backup Generator for Your Business?

Posted by IER Services on Oct 14, 2017 10:39:39 AM

All the severe weather patterns the past few months have resulted in thousands of businesses being without power. A power outage is not only an inconvenience but it can also be dangerous. 

One option is an emergency generator. When storms knock out the power grid, it can take days and even weeks to restore power. A backup generator can provide your business with temporary power during an emergency.

If you are considering a backup generator you should address issues such as smart grids and grid reliability. Also fuel prices, supply, and maintenance are key factors in life cycle costs and reliability for power generation

Permanent generators are installed outside the building and are on standby. They run on an existing fuel source such as natural gas or liquid propane and are designed to start just seconds after loss of power.

The permanent generator works in conjunction with a transfer switch to monitor incoming utility voltage. When your power goes out, the transfer switch will disconnect the utility line and connect a new power line from the generator to restore power within seconds.

In the past few years, the cost has decreased, making them more affordable. Keep in mind, a licensed electrician must install these generators, and your local utility company needs to be notified when you have a alternate system installed.

Those who live in areas that consistently sees power outages, should consider this type of generator. Also, a climate that is consistently very cold and plagued with ice storms, makes this generator worthwhile to power your business should you experience a prolonged power outage.
