Emerson has introduced the CC200 case controller. This is a stand-alone controller for virtually any type of refrigeration display case or walk-in box and all required loads. The Cold Chain Connect app was designed as a solution to communicate with the controller and provide streamlined start-up and commissioning, advanced connectivity and troubleshooting for original equipment manufacturers, end users and contractors. The microprocessor-based controller enables OEMs to manage all loads in a refrigerated case. This includes lighting, fans, defrost heaters, liquid line solenoid valves, unipolar steppers, bipolar steppers, pulse width modulation, expansion valves and electronic evaporator pressure-regulating valves. All of this takes place inside of a stand-alone unit. This controller also improves energy savings, store health scores, system reliability and food quality.
“We basically went back to a blank slate on all of our software,” said Chris Denney, a senior engineer at Emerson. “Some of what we developed for the CC200 controller was a ground-up rebuild for us. We totally rethought the way we were doing it and redesigned everything to optimize the software for the electronic valves that are used in the industry today.”
- The CC200 controller’s hardware and software have been designed, engineered and tested for low-, medium- and dual-temperature applications. Powered by advanced algorithms that deliver a connected solution, these controllers enable the coordination of refrigeration case lineups with support for up to eight cases.
- The main refrigeration controller includes an auto-tuning superheat control that reduces the time needed to pinpoint ideal settings, enabling faster commissioning. The CC200 features a new algorithm for learning and automatically selecting the optimal superheat setpoint for each evaporator. This allows the controller to balance all air temperatures in a refrigeration circuit close to the target setpoint, even for multi-coil display case designs.
- A new hardware design that maintains compatibility with Emerson sensors enables quicker system upgrades, allowing OEMs to purchase and install fewer components in the control tray than ever before.
- By adding plug-in expansion modules, the CC200 controller’s modular design can accommodate up to three evaporator coils per display case. The main controller, expansion modules and display operate on a single power source, simplifying wiring and reducing labor costs.
- Expansion modules plug directly into the CC200 controller’s side expansion port connector, eliminating the need to run separate wiring for power and communication. Color-coded analog inputs and intuitively labeled output and valve connectors allow fast and efficient installation and easier troubleshooting.
