The two termination components of the HSM serve as the basis of the modular product concept, as they allow for the integration of many additional functions with their four connection options each. Tedious sealing, additional piping or bulky attachments to the heating system are now a thing of the past. The AFRISO plug-in system turns the entire process into a snap: loosen the clip with a screwdriver, remove the plug, insert the desired accessory and reinsert the clip – done!

In this way, for example, a temperature sensor, automatic quick air vent, the boiler safety group assembly KSG, the differential pressure bypass valve or the diaphragm expansion vessel MAG can be connected in practically no time. Even for conversion to the hydraulic separator function, it is sufficient to replace the integrated sealing plug with a blind plug.
