EVRSF

Controllers for refrigerated showcases, with touch-keys, in split version and which can be integrated into the unit
EVRSF 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.
They can be adjusted for low and high relative humidity and feature an adaptive defrost system and energy-saving strategies.
Installation is by back-panel, with double-sided tape (guarenteeing flush positioning) or from the front, with self-threading screws, double-sided tape and frame (the latter requiring a shallow depth).
