HydroMixer™ Motorized Temperature Mixing Unit - NA Market

The 167 series HydroMixer™ provides a modulating three-point floating type non-spring return motorized three-way mixing valve

to regulate the fluid temperature in heating and air conditioning systems in response to a separately-sourced outdoor reset controller. It comes complete with onboard three-speed or variable-speed pump, motorized three-way mixing valve, check valve, supply and return temperature gauges, secondary circuit shut-off ball valves and pre-formed insulation shell. Versions are available with either the three-speed Grundfos UPS 15-58 pump or the variable-speed Alpha 25-55U pump.

The unit can be ordered with supply flow and pump on the right or left side. The adjustable differential pressure by-pass valve, code 519600 and wall bracket code 165001 are optional.
