EVBOX1 three-phase defrost

EVBOX1 three-phase defrost

Eletrical controllers for single-phase cold rooms with three-phase defrost heaters management
EVBOX1 three-phase defrost is a range of switchboards 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 A @ 250 VAC, for direct control of high-power compressors and the evaporator fan, thus avoiding the use of contactors. They can also be connected directly to the load.
They can be adjusted for low and high relative humidity and feature an adaptive defrost system and energy-saving strategies.
Some models have a clock for memorising HACCP alarms; all have the three-phase defrost heaters management.
The controllers are designed to be wall-mounted, with fixing screws and plugs.
