DALLAS — The new Danfoss AK-PC 781 multifunctional rack controller simplifies set-up of energy-efficient capacity control of refrigeration compressors and condensers with modular hardware and flexible software that extends as system requirements grow or change, says the company. The AK-PC 781 ensures precise, stable suction and condensing pressure regulation for a variety of applications and refrigerants.

Danfoss is also showing its second generation of variable speed compressors – VZH inverter scroll compressors – which deliver efficiency and performance in varied air conditioning applications, including VRF, chillers, rooftop, packaged or split systems, IT, process cooling and dedicated outdoor units, while providing precise temperature and humidity management, the company says.

In addition, the new Danfoss VLT® HVAC Nema/UL Type 4X drive is a solution for installations that require protection against windblown dust and rain or splashing water, and it provides an additional degree of protection against corrosion.
