WITA®UNI-Compact Heating circuit group


The WITA UNI-Compact fitting is a heating fitting made of grey cast iron. It can be used to control either the flow or return flow temperature. Its intelligent design allows it to be used with almost all threaded heating circulation pumps on the market with lengths of 130 mm to 180 mm. A mainten ance-free brass mixing head, sealed with two O-rings and virtually 100 % airtight, allows flows
from all directions. The fitting can be automated using the SM 4 and SM 44 series of WITA servomotors or other models with the appropriate assembly kit. Centre distances of 120-125 mm are avail-able upon request, as are left or right flow and return flow directions and 1 ½” or
2″ connection threads.
