Electrical Control Cabinets

Including digital controller

I

ntroduction

Designed to facilitate installers work, this range
of electrical cabinet is intended for use in cold
rooms working at positive or negative
temperatures and powered either with single
phase or three phase power supply.

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
down”.

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

Particular attention has been given to the
accessibility so that the installation time will be
reduced to a minimum. Space has been left
available for customisation.
