ADAP-KOOL® pack controls ensure accurate control and operational reliability for advanced solutions
Danfoss offers a range of compressor and condenser capacity controls for use in food retail, in compact systems, as well as in large power packs.
The ADAP-KOOL® pack controls ensure accurate control and operational reliability for advanced solutions for controlling up to twelve compressors. The intelligent controllers optimize the suction and condensing pressure according to load and outdoor temperatures.
Additional energy savings and low maintenance costs can be achieved by using variable speed control of condenser fans and compressors and other advanced features such as adaptive defrosting, self-diagnosis and automatic fault detection.
The capacity controls provide a good diagnostic tool for remote servicing with almost all parameters accessible remotely.

Benefit from robust and efficient solutions built on superior know-how
Danfoss compressor and condenser control solutions cover the full range from compact controllers for small pack systems to advanced controllers for up to 12 compressors and 8 fans.
