Thermostatic regulator

Thermostatic regulator 605

The COMAP hot-water thermostat is a central thermostatic temperature regulator for distribution of domestic hot water. It is installed after the water tank or boiler if the internal temperature is greater than 60°C.

It is used to provide water at a given temperature from hot and cold water sources.

Benefits of the thermostatic regulator

  • Saves hot water
  • Used to separate the temperature of stored hot water from that distributed
  • Increases the volume of hot water distributed
  • Low pressure drop permitting high flow rates
  • Foolproof fitting
  • Protected from contamination by non-return valve
  • Lockable handle
  • Can be fitted in all positions
  • Long-lasting installation

Applications of the thermostatic regulator

  • Max. pressure: 10 bar
  • Max temperature: 100°C
  • Output temperature: 605: 40 to 60° C; 605 S: 35°C to 55°C
  • Size: 3/4"

Applications and uses of the thermostatic regulator

  • The thermostatic regulator provides water at the desired temperature using hot and cold water sources.
  • For use in systems with 16 water outlets or fewer, because of coincidence factors.
  • For non-residential uses, the regulator can supply a maximum of 4 showers (for example, in communal showers).
  • It is often necessary to fit hot water regulators in parallel in order to use additional outlets.

Installation recommendations of the thermostatic regulator

  • The recommended water supply pressure is between 2 and 5 bar, with a maximum flow velocity of 1.5 m/s.
  • The regulator should be located just after the hot water generator.
  • The cold water pressure should always be about 0.2 bar greater than the hot water pressure.
