Modular heating circuit K31 DN25 unmixed

The modular heating circuit K31 is suitable for both the modulating of temperature heating systems and for boiler charging.

Properties:
The connections of the heating circuits have an internal thread of 1". Large ball valve handles facilitate the operation and clearly indicate the closed position. The modular heating circuit is equipped with function-optimized design insulation made of durable elastic EPP, which insulates the fittings 100%. Additionjally, the system provides a ventilation duct to cool the pumps.
Free access to the pump head is ensured by simply removing the front insulation shell.

The heating circuit has gravity brakes (can be opened, 200 mm water column, spring-loaded) in the return pipe to prevent noise generation when using electronically-controlled pumps. The modular heating circuit is suitable for horizontal and overhead installation.

The flow is pre-installed by default on the right, flow and return line can be changed though. All the water-bearing parts of the heating circuit are made of brass. The modular heating circuit is assembled with flat gaskets. The all-metal thermometer as handle in the ball valve can be pulled off and is equipped with an integrated immersion sleeve. The pump used can be fully shut off so that the modular heating circuit need not be drained in case of maintenance work.
