CLIMASET srl offers CAREL EVD driver for managing every electronic expansion valves, from CAREL or from other manufacturers.
These drivers keep overheating to the desired value and can manage a great variety of refrigerants, from small domestic heat pumps to big industrial aero-evaporators, passing to precision conditioning units or process and conditioning chillers.
CAREL EVD drivers drivers offer high efficiency, configuration semplicity and advanced functions for compressor protection.
EVD Evolution
The EVD Evolution series is the last stage of development of CAREL drivers for overheating management. The device has a new easier user interface: a programming procedure permit to start the regulation by selecting the refrigerant in use, valve model, pressure vale type and the application type (if you use the device for controlling CAREL valves, you just have to select three parameters).
Other features are:
- Overheating regulation with auxilliary protections for high pressure, low pressure and low overheating,
- Usage of low-power ratiometric low-pressure transducer with a 4…20 mA output (shared also with more than one driver),
- Second digital input for thawing, possibily to use backup probes.
With CAREL ExV series electronic expansion valves, the EVD driver allow for optimizing the working of the evaporator and achieving big energy savings.
EVD Evolution
EVD Evolution Twin it he control composed by two drivers for bipolar step-step for indipendently managing two electronic expansion valves.
It is predisposed to be mounted on DIN rail and has extractable screw terminals. Every driver allows for regulating overheating refrigerant and for optimizing the yield of the refrigeration circuit: it is compatible with various refrigerant types and valves, in applications with chiller, conditioning and refrigerators, these last one also with subcritical and transcritical CO2.
- Overheating regulation with auxilliary protections for high pressure, low pressure, low overheating;
- Special regulations as the hot gas by-pass, EPR evaporator pressure regulation and command of downstream gascooler valve in transcritical CO2 circuits;
- Optimization of the overheating regulation dedicated to conditioning units that are equipped with Digital Scroll compressor, if embedded with specific CAREL controller via pLAN, with the possibily of starting one or more sintonization procedures (tuning);
- Starting of the assisted procedure with only 4 parameters (if you use the device for controlling CAREL valves, you just need 3 parameters);
- Use of low-consumption ratiometric pressure transducer with a 4…20 mA output (this last one can be shared up to 5 drives), useful with channeled applications.
EVD ICE
EVD ICO manages electronic proportional expansion valves CAREL ExV, it may also be installed on the evaporator for refrigerated rooms or other applications, it is engineered for using also with low temperatures. EVD ICE is suggested for factory installations becaused is equipped with all precabled accessories, including the electronic expansion valve and all sensors needed. EVD ICE is capable of working with regulation and thir-pary supervision or in standalone mode.
