EKE
Type EKE 100
Introduction
Superheat controller EKE 100 is for use where superheat must be accurately controlled or as driver for
stepper motor valves typically in air conditioning, heat pumps, commercial refrigeration, food retailing
and industrial application.
Compatible valves: ETS 6, ETS 8M(Bipolar)/ETS C/KVS C/ ETS L/ETS 500-800P/ CCMT L/CCMT/CCM/CTR
