CAREL introduces a new driver for electronic expansion valves at ChillVenta (Hall 6, Booth 6-104). The new EVD EVOLUTION driver is the most advanced and versatile solution for superheat control with electronic expansion valves to achieve energy saving in the HVACR systems.

 

EVD EVOLUTION indeed represents the evolution of the EVD 400 range, and consists of a basic controller with LED signals plus optional backlit LCD with keypad, available in different languages, with help on the parameters and installation diagrams, useful as reference for installers. Special focus has been placed on usability: EVD EVOLUTION offers a new extremely easy and user-friendly programming method, making the expansion valve immediately operational. Using the auto setup function for the control parameters, only four parameters need to be configured: refrigerant, model of valve, type of pressure probe and application.

Another detail making it user-friendly is the graphic LCD, allowing simple and effective management of the operating parameters. The main system variables are represented in graphic form, thus instantly displaying the status of the system, a useful function above all during maintenance and commissioning. EVD EVOLUTION is available in the convenient stand-alone version for refrigeration units with compressor on board (for example, the display cabinets) and the high-performance version, integrated with the CAREL pCO series and µC2 controllers for chillers and precision air-conditioning units.

 

For more effective integration, CAREL control systems are available with the VPM commissioning tool (Visual Parameter Manager), commissioning and monitoring software with parameter configuration wizard, Modbus protocol, connection to the PlantVisorPRO supervisory system and the 1Tool software development package for the complete programming of the pCO sistema series controllers, reveals the company’s press release.
