Altecnic 116 Thermostatic Regulator for Hot Water Recirculation
The Altecnic thermostatic regulator for domestic hot water re-circulation systems automatically maintain the specified water temperature.
The thermostatic regulator is intended to be installed in the return pipe of each re-circulation circuit, automatically maintaining the specified water temperature. The regulator controls the flow rate in accordance with the inlet water temperature by means of a dedicated internal thermostatic cartridge. When the water temperature approaches the set value, the obturator progressively closes and reduces the flow passage reducing the amount of water re-circulating.
The water supplied by the re-circulation pump is available to be distributed to other branches in the system, resulting in effective automatic thermal balancing.
