Retail Refrigeration Temperature Monitoring

A case controller is an intelligent device designed to regulate and optimize refrigeration cases and other cooling equipment. By continuously monitoring temperature, humidity, and other critical system parameters, case controllers ensure precise control over refrigeration performance, helping businesses maintain food safety, improve energy efficiency, and reduce operational costs.

The CC200 is a powerful retail refrigeration system for managing refrigerated display cases and cold storage applications. It integrates seamlessly into distributed refrigeration systems, providing real-time monitoring and automation to enhance performance and reliability. With advanced features like remote connectivity, alarm notifications, and adaptive control algorithms, the CC200 helps facility manager streamline operations while meeting stringent regulatory requirements.

Copeland’s CC200 case controller is made up of four main components: the main controller, the expansion module, the case display and our new Cold Chain Connect mobile app for Bluetooth connection. It is designed for controlling air temperature, superheat and evaporator pressure for refrigerated display cases and walk-in boxes. It can control low, medium, and dual temperature case designs and a variety of loads and valves. This controller is compatible with a variety of synthetic refrigerants and CO2.

The CC200 case controller’s solution supports control of up to three evaporator coils and one stepper EEPR valve, as a maximum. The expansion module is a valve driver with onboard input and output capacity to handle additional evaporators and valves that need to be controlled. Each expansion module comes with PWM and stepper valve outputs which allow addition of one additional expansion valve. The expansion module valve compatibility is the same as the CC200 main controller so any valve that is approved on the main controller can also run on the expansion module. The expansion valve is not a stand-alone component and must be used with the CC200 main controller.

When you achieve the precise temperature, superheat and pressure performance results while reducing time spent during system commissioning, without paying for labor to adjust TXV’s in every case or to tune evaporator pressure setpoints, it simplifies refrigeration system startup and maintenance post startup. Labor expenses are reduced, and startup complexity is reduced. With over 40 data points about evaporator and controller operation and 12 service commands available in one screen, diagnosing or simply checking system operation has never been easier.

For retailers and OEMs that want the capability to switch between fresh and frozen applications within the same display case, the CC200 case controller offers dual temperature case design support. Separate low- and medium-temperature setpoints for air temp and evaporator SST (when EEPR is used) make it easy to configure the CC200 for dual temperature operation.
