Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum systems.

RectorSeal LLC has introduced the RectorSeal HVACR (RSH) Series of surge protective devices (SPD). The permanently-installed RSH Series is designed to protect all single phase, 120/240-V air conditioning, heat pumps, and ductless mini-split systems (DMSS) from transient over-voltage and natural-cause surges.

Heat Transfer Products Group LLC (HTPG) debuted its ColdZone Dual-Pak Multi-refrigerant Air Cooled Condensing Units for walk-in cooler and freezer applications.

Cooper&Hunter added a new series to its current heat pump line-up with single-zone applications. The new Dakota series aims to ensure consistent warm comfort during extreme climate and the condenser heat output capacity allows the unit to work efficiently as a primary heat source even if the temperature drops to a sub-zero level of minus 22ºF.
