TM50/TM200/TM300SOLAR

Thermostatic mixing valve with scald protection for solar installations

Product specification sheet

TM50SOLAR

TM200SOLAR

TM300SOLAR

Construction

The thermostatic mixing valve comprises:

•Housing

•Connection fittings (not in TM50SOLAR)

•Adjustment knob

•Thermostat

•Protective cap to fix the set mix water temperature (not in TM50SOLAR)

Materials

•Dezincification resistant brass housing, nickel plated

•Dezincification resistant brass connection fittings, nickel plated (not in TM50SOLAR)

•Moving parts of high-quality, scale-resistant synthetic material

•High quality-synthetic material adjustment knob

•Stainless-steel spring

•Protective cap made of transparent plastic (not in TM50SOLAR)

Application

Thermostatic mixing valves of this type are used for central regulation of the water temperature in solar-powered, bivalent water heaters.

A cold water break can be fitted in the circulation line in water heater systems, which prevents cold water from mixing at the extraction point via the circulation line.

Special Features

•Highly sensitive thermal element with good all-round watertemperature sensing, even at low flow rates

•Simple setting of the required water temperature

•Scald protection - the hot water inlet is automatically cut off if the cold supply fails provided that the hot water inlet temperature is at least 10 K higher than that of mixed water setting

•The cold water inlet is automatically cut off if the hot supply fails

•Meets KTW recommendations for potable water

•Inner components are of scale-resistant materials

Method of Operation

Thermostatic mixing valves of this type are used for central regulation of the water temperature in solar-powered, bivalent water heaters.

The highly sensitive thermal element located in the outlet of the valve controls a plug which regulates the flow proportions of cold and hot water in relation to the mixed hot water setting selected. Soft seatings are fitted to both hot and cold water inlets.

They provide:

•A positive hot inlet shutoff if the cold water supply is interrupted, provided that the hot water inlet temperature is at least 10 K higher than that of the mixed water setting.

•The cold water supply is cut off if the hot water supply is interrupted.
