EVF

Controllers for refrigerated showcases, with touch-keys, in split version and which can be integrated into the unit
EVF is a range of elegantly designed controllers for the management of refrigerated showcases.
They are available in split version and can be integrated both mechanically and aesthetically in the unit; the user interface consists of a custom display of above average size (with decimal point and function icons), six touch-keys and guarantees an IP65 protection rating, for easy cleaning.
The controllers have a 30 res. A @ 250 VAC electromechanical relay for the direct control of high power compressors, avoiding the use of contactors and with direct load connection.
Some have the real time clock (to store the HACCP alarms); all can operate with low or high relative humidity percentages and have adaptive defrost management and energy saving strategies.
Installation is by back-panel, with double-sided tape, guarenteeing flush positioning.
