Caleffi ThermoProtec™
boiler protection high-flow thermostatic mixing valve
The ThermoProtec™ boiler protection high-flow thermostatic mixing
valve is used in hydronic heating systems with non-condensing boilers,
including solid fuel, biomass, gas, LP or oil-fired. It can be installed with
steel, cast iron and copper tube style boilers, automatically controlling
the return water temperature, preventing condensation of the water
vapor contained in the flue gas. The 280 series ThermoProtec™ valve
mixes by-pass flow from the boiler with return flow from the system,
sending a fixed temperature flow to the boiler which protects against
corrosion from condensation occurring when a minimum flue gas
temperature is not otherwise maintained.
Changeable thermostatic sensor cartridge changes valve temperature
setting. The thermostatic sensor cartridge can easily be removed for
maintenance or to change the valve set temperature, with out removing
the valve body from the piping.
