Variable-speed technology has the obvious benefit of providing users with additional choices when it comes to running their HVAC equipment. Rather than one setting that runs at 100 percent all the time, variable-speed allows for layered, configurable settings.
AC drives are an essential part of the HVAC marketplace, and the growth of the market looks to be exceptional over the next few years. According to MarketsandMarkets, the market is expected to grow from an estimated $15.72 billion in 2016 to $22.07 billion by 2021.
This close-coupled, horizontal, end suction pump is designed for service in general pumping, chemicals, wash systems, deionized water, process, and OEM applications. It is designed for long life in tough services with flows to 240 gallons per minute (GPM).
In the realm of motors, the permanent magnet synchronous motor (PMSM) is a relatively obscure option that is gaining significant traction in the space.
This mobile app is used for Vilter™ Select software, an online tool that allows users to determine capacities of all Vilter reciprocating and screw compressor lines. The mobile app is an extension of the technician-focused selection software, providing in-the-field analysis capabilities necessary to select the most efficient compressor.
This zone valve is for use in hydronic heating and other HVAC systems, such as those with fan coils and air handlers. The mechanical valve allows one actuator to accept input voltages between 120 and 277 vac 50/60 HZ.
These power blocks are rated 175 A and 600 V for electrical applications in power panel distribution. The blocks can also be used for lighter power applications and, therefore, have extended utility as a one-size-fits-all product line.
Bob and Tim are on a service call on a really cold and blustery day. The temperature is 27°F, the wind is blowing, and it’s snowing and sleeting. When the customer called, she said that their home is getting cool inside, and their heat pump is running all the time with the temperature dropping inside the house. They arrived at the front door, talked to the homeowner, and decided to look around. They went to the closet where the indoor unit for the heat pump was located and determined that the heat pump itself was not running, only the fan and strip heat.
Designed for water-cooled chiller applications and built with Turbocor technology, the TT700 compressors are oil-free, variable-speed, magnetic-bearing centrifugal compressors that provide full- and part-load energy efficiency.
