EVK231
Digital controllers for static refrigerated units
management
The EVK products are a controllers line able to manage static refrigerating units by the control of compressor and defrost. Multicolour function icons allow to understand, with a fast look, the refrigerator status; display composed by 3½ digits allows to show decimal point value also below -10°. Defrost management is made by stopping the compressors except for the models EVK202 and EVK212 where the defrost management is made by temperature/time. EVK241 and EVK251 thanks to the control of condenser temperature allow to signal clean/maintenance needing on plant or allow to lock the system to avoid compressor damage.Moreover, EVK242 model is able to manage two independent compressors (in two different cabinets) thanks to the presence of two independent cabinet probes. Excluding EVK201, the EVK line has by request a serial port
with ModBus communication protocol for the connection to RICS supervision software and for the connection of EVKEY quick-setting system, alarm buzzer and output for EVT100 remote repeater connection (this last for EVK211, EVK221, EVK241, EVK202, EVK212 and EVK242 only).
