Varimix Pro VAR 20
Mixing Pump module

Features

• VARIMIX Pro VAR 20 is a pre-assembled group of Brass and Stainless-Steel fittings for temperature control of heating and cooling circuits. The circulator can be conveniently maintained by isolating it, using the ball valves and mixing valve.
• The VARIMIX Pro VAR 20 should be mounted on a modular VARIMIX PRO VAR 30 distribution manifold.
• The VAR 20 mixing module with floating action 3-way valve diverts and mixes radiant return water to the radiant loop manifolds.
• In conjunction with a separately sourced electronic reset control and direct drive actuator it regulates the fluid temperature in hydronic heating and cooling Systems. Two thermometers display the temperatures of the supply and the return, providing a way to monitor system’s function.
• The integrated check valve avoids unwanted circulation/ heat migration. The insulation shell prevents heat energy loss during heating operation. During cooling operation, the insulation reduces possible condensation.
• The standard unit comes with supply on the left and can be ordered with supply flow and pump on the right or can be field modified to accommodate changing installation requirements.
• The adjustable differential pressure bypass valve, P/N 550635LNA is optional.  The unit comes with male G1 thread connections (upgradable to G1-1/2” ) which require G-Union fitting kits (sold separately).
