Product Description
The CRC-2052 Digital Cold Room Controller Panel is designed for single compressor cold rooms operating in negative temperature ranges, suitable for capacities from 7.5 HP to 10 HP. It provides complete system control and protection for low-temperature refrigeration applications such as freezers and deep cold storage.
This controller operates on a single set point with differential control logic, ensuring precise temperature maintenance. It supports both heater-based and hot gas defrost systems, allowing efficient frost removal while maintaining system stability.
The CRC-2052 is equipped with multiple safety features including high/low pressure protection, compressor overload and underload monitoring, and fault detection systems. It also includes alarm indication with buzzer alerts for temperature deviations or system faults, ensuring safe and reliable operation.
With advanced programmable parameters, the controller allows configuration of defrost timing, differential values, compressor delay, and alarm limits. It also supports optional RS485 communication for remote monitoring and integration into BMS systems, making it suitable for modern industrial refrigeration setups.
