ntroduction
Designed to facilitate installers work, this range
of electrical cabinet is intended for use in cold
rooms working at positive or negative

Based on specifically designed controllers, it
incorporates all control functions as required by
modern cold room units, such as compressor
control, defrost management, fan management,
alarm function and solenoid valve for “pump

It also includes all the safety equipment needed
such as circuit breakers for the compressor and
