Crysalisâ„¢ controllers and sensors are designed for the control, supervision, and networking of commercial refrigeration, HVAC, and lighting systems for supermarkets and other retail facilities. According to the manufacturer, the company has brought together the best of two worlds - its line of commercial refrigeration controllers and equipment and Invensys' line of HVAC and lighting controls. The CWeb Web services gateway enables multiple users to monitor and supervise refrigeration, HVAC, and lighting controllers over an intranet or the Internet via a Web browser. The product family is backward-compatible with the company's line of existing system components, including the 4K, 4K2e, and 4500 refrigeration controllers.
