Multifunctional pack controller
Danfoss’ new AK-PC 781 Multifunctional Pack Controller makes it easier to set up energy-efficient capacity control of refrigeration compressors and condensers with modular hardware and flexible software. The AK-PC 781 ensures precise and stable suction and condensing pressure regulation for many types of applications and refrigerants. The modules snap onto a common platform to accommodate digital and analog inputs/outputs for compressors, condensers and gas coolers. Capacity control is available for up to eight compressors with three unloaders for each compressor.
