166 series HydroMixer
The 166 series HydroMixer™ provides a fixed temperature flow to
low temperature secondary heating circuits (such as floor radiant
panels), complete with onboard three-speed or variable-speed pump,
thermostatic three-way mixing valve with built-in temperature sensor,
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, and the unit is field reversible to accommodate changing
installation requirements. The adjustable differential pressure by-pass
valve, code 519600 and wall bracket code 165001 are optional. The
unit comes with male union connections which require separately
purchased, 1 inch sweat or NPT, top outlet and bottom inlet fitting
kits.
