Maxey Moverley pack controllers can be configured to cope with a wide range of refrigeration installations, by a combination of switch settings on the circuit boards and parameter values introduced using our separate Setup Unit. The pack controller is a microprocessor-based system for controlling and monitoring compressors in refrigeration installations. Each pack controller can handle a low temperature (LT) pack of up to 8 compressors, or a high temperature (HT) pack of up to 8 compressors, or can combine booster packs each of 4 compressors (or 16 stages in total). The booster pack controller can interlock the stages so that no low-side compressor can run unless at least one of the highside compressors is running.
