Compressor Sequencer

Compressor Sequencers are designed for small to mid-sized racks, The Compressor Sequencers brings the controller’s features in line with the job’s requirements. It eliminates the necessity of using overly complicated controls designed for larger systems. The controller supports up to 5 stages of loading through its on-board relays. Each relay can be configured as the rack’s: Fixed Speed Compressor, Compressor Unloader, Digital Scroll Compressor, Master Liquid Line Solenoid, or Hot Gas Defrost Relay. The compressor sequencer works as a stand-alone rack controller or in conjunction with KE2 Evaporator Efficiency controllers. When applied with the KE2 Evaporator Efficiency controllers the Compressor Sequencer can limit the amount of defrost load, as dictated by the site’s electrical requirements.

• Designed for small to mid-sized racks - eliminates overly complicated controls
• Easily applied to new or existing installations.
• Supports up to 5 stages of loading with on-board relays
• On racks with compressors all of equal HP, will automatically equalize runtime
• Racks with compressors of varying HP, it maintains consistent suction pressure
