Accessories

EVBOX1 is a range of electrical controllers for the management of single-phase cold rooms.
The user interface consists of a large custom display with decimal point and function icons, with six buttons. It guarantees IP65 frontal protection.
The controllers use two relays, rated load 30 res. A @ 250 VAC, for direct control of high-power compressors and of the evaporator fan, thus avoiding the use of contactors.
They can be adjusted for low and high relative humidity and feature an adaptive defrost system and energy-saving strategies.
Some models have a thermal-magnetic circuit breaker, a clock for memorising HACCP alarms and include a driver for unipolar stepper-type electronic expansion valves.
The controllers are designed to be wall-mounted, with fixing screws and plugs.
