Compact variable frequency drives (VFDs) can deliver energy savings by controlling pumps or fans in commercial HVAC equipment. They are micro drives and save space in HVAC controls equipment cabinets. Features include a standard proportional integral controller.
The refrigeration system analyzer features a digital, full-color thin film transistor display with adjustable brightness and contrast protected by an anti-glare, scratch-resistant lens. The display reads in analog, digital, or a combination of both.
The Envision™ NXW Series of reversible chillers are now available in 8- to 20-ton sizes. These water-to-water heat pumps provide water heating and cooling for a wide range of applications, including pools, commercial aquariums, radiant floor heating, ice melt, and chilled-water.
The OASys™ indirect/direct evaporative cooler contains an Indirect Cooling Module, which first cools incoming fresh air without adding moisture. The air then passes through the direct cooling module, is cleaned, and humidity is optimized. Cooled air enters the space directly or through conventional duct configurations.
With its unique locking features, this damper regulator locking extension provides significantly increased labor and time savings, offering a quick and easy installation that does not require the use of a small set screw and enables last-minute field changes to be completed in a matter of minutes, said the company.
WhisperValue FV-10VS1™ and WhisperValue-Lite™ FV-10VSL1 ventilation fans offer Energy Star® qualification, high airflow circulation, and low noise with a slim profile. Ventilation fans can mount in a slim 2- by 4-inch joist cavity, minimizing installation times. FV-10VS1 is UL-listed for wall installation.
The E-Series commercial and industrial heating direct-fired air turnover system combines a 100 percent-efficient direct-fired burner with highly efficient direct-drive, VFD-controlled axial fans. Heated supply air is discharged at the top, “washed” across ceilings to push warm air downward, and circulated through the space.
The 2-inch Wirsbo hePEX™ Expansion Joint Kit offers a quick, efficient solution for commercial building closed-loop, above ground, radiant heating and cooling distribution applications that require an expansion joint for every 50 feet of tubing. The kit includes one preformed loop of tubing, two elbows, and four rings.
A full range of variable air volume (VAV) terminals are available as part of an expanded product line for commercial and light commercial HVAC systems. The VAV terminals can be utilized in large, complex facilities as well as medium-sized and low-rise buildings. Airflows range from 100 to 8,000 cfm.
