Simply Cool and Smart
Peace of Mind
With our CO₂ scroll technology, we enable worry-free solutions tailored to your needs and ensure your peace of mind.
Refrigeration with CO₂ depends on a refrigeration system that operates in a reliable, efficient, and self-contained manner. Therefore, we developed a new generation of scroll compressors equipped with innovative injection technology. You can count on it.
For a refrigeration system to operate perfectly, it is crucial that the refrigerant is injected, compressed, and circulated accurately at exactly the right time. Our new generation of scroll compressors equipped with innovative injection technology for flash gas management are designed to do exactly that. A suite of intelligent electronics optimizes system performance. At the heart of the technology is the new Copeland XC Pro CO₂ scroll controller – designed specifically for booster applications and refrigeration units.
Fewer Components Reduce Complexity
The application of Dynamic Vapor Injection (DVI) allows for flash gas to be directly injected from the economizer or the flash gas tank into the compressor by a dedicated valve. While the controller adjusts the injection pressure to optimize the system performance. This eliminates the need for parallel compression and therefore enables the cooling circuit to be operated with less system components such as parallel compressor with inverter drive. Thanks to DVI, the refrigeration system operates at high efficiency regardless of the climate. And with less components reducing its complexity dramatically.
Higher System Efficiency
The suite of intelligent electronics is managed by the new dedicated Copeland XC Pro CO₂ scroll controller with smart control logic. It monitors, analyzes, and optimizes the different system components to deliver high system efficiency, safe compressor operation and enables lower pressure design.
Inteligencia y seguridad
La digitalización del circuito de enfriamiento ayuda a los técnicos de servicio a realizar el diagnóstico correcto en caso de que haya problemas en el sistema.
Muchas mejoras
La digitalización es clave cuando se trata de aumentar el rendimiento del sistema. Es un medio para registrar, analizar y evaluar los datos de los componentes del sistema y su funcionamiento. La conexión de nuestro controlador de sistema inteligente a un sistema de gestión de edificios (Building management system, BMS) proporciona ventajas de digitalización como el diagnóstico remoto, el mantenimiento predictivo, el análisis del rendimiento y el análisis exhaustivo de datos: una gestión holística de la tienda inteligente y la capacidad de extraer conclusiones de los datos para una mayor optimización de los procesos.
