The EVD evolution series of controllers for electronic valves is the latest step in the development of the famous CAREL drivers for superheat control. Compared to the standard EVD, this instruments adds advanced functions and a new user interface that makes it even easier to use and configure. The new TWIN version can independently control two electronic expansion valves, and represents the ideal solution for two circuit units or different control function (i.e. superheat and hot gas bypass). A new graphic display and a simple programming procedure allow the controller to be started by selecting just 4 parameters:   - refrigerant used; - model of valve; - type of pressure probe; - application (chiller, display, cabinet, etc.), selected from the multiple choice menus. EVD evolution is complete with LEDs for controlling the main functions, and can house a removal LCD display for the configuration and monitoring of all the variable. EVD evolution can be...

Carel electronic expansion valves E2V with proportional modulation and excellent technical and functional characteristics, allow an efficient control of refrigeration and air-conditioning units , and consistent energy saving performance. The flow of refrigerant is modulated by nozzle coupled to a torpedo shaped aperture, measuring more than 15 mm long, over a wide operating range. The internal mechanism is fitted on a calibrated spring with ball bearings and guarantees a stable and reliable regulation reducing the risk of failures. E2V is completely manufactured using laser-welding techniques on high-quality materials (AISI 316L), as well as technopolymers. Carel has paid special attention to the smallest details in designing E2V to ensure very high reliability for operations up to 35 bars of differential pressure and up to 45 bars of absolute pressure. Other features include exclusive axial motion of the nozzle aperture and seal gasket in the closing position. By install...

Ultracap is the new emergency power supply device for electronic valves , the natural completion of the EVDEvo, both single and twin versions, ensuring complete closing of the valves even when there are mains power failures. Exploiting ELDC (Electric Double Layer Capacitor) technology, Ultracap can supply immediate, reliable and clean emergency energy, representing a major step forwards compared to conventional battery-based systems, including as regards disposal of used materials. Ultracap has been designed to give 10 years trouble-free silent operation, without requiring periodical checks or having to replace batteries. Ultracap means immediate energy: just 5 minutes (4 minutes for Carel valves) after power is restored, the system is already recharged and active (in practical terms the same time the compressor takes to start...). The extreme reliability of Ultracap combined with the exceptional tightness of Carel valves , eliminates the need for solenoid valves even in the m...
