Temperature Controllers
KE2 Compressor Sequencer Controller
KE2 Compressor Sequencer Controllers allows control of up to 8 stages of loading for a single suction group, or up to 10 stages of loading (5 per suction group) for dual suction groups.
Overview
KE2 Compressor Sequencer Controllers allows control of up to 8 stages of loading for a single suction group, or up to 10 stages of loading (5 per suction group) for dual suction groups. For dual suction groups, the controller is applicable to both racks with a shared common discharge, or independent discharge lines. Suction pressure can be controlled to either a fixed set point, or a floating suction pressure for maximum efficiency. Each stage of loading can be set to: fixed speed compressor, variable speed compressor, digital compressor or unloaders. The relays for the stages can alternatively be used to control a Master Liquid Line Solenoid, or as a Hot Gas Defrost Relay.
Features & Benefits:- Designed for small to mid-sized racks - eliminates complicated controls designed for larger systems
- Supports up to 5 stages of loading with onboard relays. 5th stage needs digital switch
- On racks with compressors all of equal HP, will automatically equalize runtime
- Racks with compressors of varying HP, it maintains consistent suction pressure
- Master View webpages allows tech to quickly and easily assess system’s operation
