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.”
From Emerson:
- 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.
