Altecnic has introduced a new thermostatic regulator for domestic hot water recirculation.
The 116 thermal balancing valve is intended to be installed in the return pipe of each recirculation circuit, automatically maintaining the desired water temperature. The regulator controls the flow rate in accordance with the inlet water temperature using a dedicated internal thermostatic cartridge. When the water temperature approaches the set value, the amount of water recirculating is automatically reduced.
If a temperature higher than 65˚C is reached, a second thermostatic sensor controls the disinfection process, allowing circulation independent of the action of the first thermostat. This ensures a flow of hot water through a special bypass as the temperature increases to 70˚C. If the temperature rises above this, the flow through the bypass circuit is reduced to allow thermal balancing during the disinfection process. Should the temperature reach around 75˚C, the regulator ensures minimum flow rate so that water does not circulate at too high a temperature.
Among the accessories available for the 116 thermostatic regulator is a thermo-electric actuator, a 24V or 240V electric actuator and a cartridge for use with the electric actuator.
