Thermax distribution system DN20 K31/K32 servomotor SR2 2x GF UPM3 Auto L 15-70

The modular distribution system Thermax is a pre-assembled fitting group for heating circuits. It consists of a Thermax modular distributor, two Thermax heating circuit modules and a design insulation with optimised function. Thermax can be directly wall-mounted or by means of distant pieces at a distance of 100 mm. This means that additional flow lines to the boiler can be installed behind the Thermax. Complete hydraulic separation between the connected circuits and the boiler is possible. The adjustable bypass (0 - 100%) of Thermax guarantees forced circulation in the boiler when the bypass is open.
Thermax distribution system consists of:
1 x K31 direct heating circuit, 1 x K32 mixed heating circuit
