Product details
Product Description
The CRC-2020 Digital Cold Room Controller Panel is designed for single compressor cold rooms operating in positive temperature ranges, suitable for capacities from 7.5 HP to 10 HP. It provides complete control and protection for refrigeration systems, ensuring stable cooling performance in commercial and industrial applications.
This controller operates on a single set point with differential control logic, maintaining precise temperature conditions. It supports time-based defrost functionality, where the compressor is stopped during defrost cycles, allowing efficient frost management and system reliability.
The CRC-2020 includes advanced safety features such as high/low pressure protection, compressor overload and underload monitoring, and fault detection inputs. It also provides alarm indications with buzzer alerts for temperature deviation or system faults, ensuring safe operation.
Equipped with multiple control and monitoring parameters, the controller allows configuration of defrost timing, differential settings, compressor delay, and alarm limits. Optional RS485 communication enables remote monitoring and integration into building management systems (BMS).
