The EXV sistema range of refrigerant control valves and drivers, including trans-critical CO2, has been expanded to include refrigerating units with capacity from 1 to 2,000 kW (0.25 to 560 ton). Series EVD Evolution control drivers have more functions, including a twin version that can be considered as two independent drivers in one instrument: two valves can be controlled independently using just one 4DIN module. This provides an effective, compact solution for superheat control on twin-circuit units.
