Nicab Due® and Nicab Maxi® Valves

The Nicab Due ballvalve for secondary refrigerant systems is a development from the Nicab STANDARD, specially designed to handle low temperatures and different types of secondary refrigerants like Glycol, Freezium, Hy-Cool, Temper and Tyfoxit. The valve is ON/OFF type, the ball in the 3-way valve has a special drilling which gives a secure and stable flow through the valve even when the valve is shifting port, for example in defrosting. The valves are manufactured as both 2 and 3 way depending on system design. The same type of actuator is used for all valves regardless if it’s 2 or 3 way. On the top of the actuator there are two LEDs that indicates cooling and defrosting. To control the valve you can use a thermostatic control with an open/close contact. The voltage is 230 V or 24 V depending on design. There is also two potential free contacts on plint to receive a signal back from the micro switch.

Nicab Maxi is a motorised ballvalve for control of secondary refrigerant systems down to -15 °C. The valve function is ON/OFF and it is compatible with most secondary refrigerants including Glycol, Freezium, Hy-Cool, and Temper. The actuator is equipped with two LEDs that indicate cooling or defrosting and two potential free contacts for extern signal or feedback.
