Carel EVD Evolution Twin refrigerant control valves and drivers

Carel has expanded its EXV sistema range of refrigerant control valves and drivers for capacity from 1 to 2000 kW.

The EVD Evolution series control drivers have been enhanced with new functions, with the introduction of the Twin version. EVD Evolution Twin can be considered as two independent drivers in one instrument: two valves can be controlled independently using just one 4DIN module.

This is an effective and compact solution for superheat control on twin-circuit units. Features offered by this Twin driver (now also available on the single valve version) involve autotuning or self-adaptive algorithm, a battery module with minimum charge signal and the proprietary algorithm for superheat control on units with Digital Scroll compressor.

The EVD Evolution Twin driver features a user-friendly graphic display for simple and effective management of the evaporator operating parameters. The driver is available in both stand-alone version for refrigeration applications such as cold rooms and in the high-performance integrated solution with Carel pCO series controllers for chillers, heat pumps and close control air-conditioning units.
