Electronic controller for compression racks and chillers. It performs the pressure and saturation temperature control and monitoring of the refrigerating fluid or the temperature of a secondary flow (glycol, cold water, environmental temperature) through up to 6 settable sensors.

Aimed to minimize power consumption of the refrigeration system, it has a new control logic: the progressive algorithm, which adapts the cold demand required by the plant with the power of the compressor group, reducing the number of turn-ons and turn-offs of the equipment. Through the floating condensation control function, it monitors the external environment temperature to lower the condensation setpoint, thus reducing the compression rate of the system and its power consumption. On its part, the integral-proportional control aims to minimize the temperature/pressure variations in the suction and discharge lines.

RCK-862 is a control module that acts on its own or with an expansion module RCK-461 to increase the number of inputs and outputs in large-size systems. Its internal solid-state relays facilitate and reduce costs in the setup of command boards.
