Introduction
The KE2 Evaporator Efficiency (KE2 Evap) is an electronically op-
erated evaporator controller engineered to save energy in re-
frigeration systems through precise control of superheat, space
temperature, fan cycling, reducing compressor runtime, and
KE2 Evaporator Efficiency - Controls and Communicates
implementing demand defrosts. The KE2 Evap offers quick pay-
back, and a life expectancy that matches that of the system. The
controller pays for itself, and then continues to pay dividends for
the life of the system.
