Modules and components for water boilers

Modules and components for water boilers:

Feed/return flow switch
Return water temperature maintenance module
APH air heating system

Feed/return flow switch VL/RL

Supply flow connector

Flange connector containing safety equipment for closed systems. The backflow connector is installed with a level limiter, manostat pipe with shut-off valve, shut-off valves (with drain, test function), pressure display, shut-off valve with maximum pressure limiter.

Backflow connector

Flange connector with additional temperature sensor (1/2″ x 90 lg.) and connection for safety expansion pipe.

Return water temperature maintenance module RTH

All components, such as the flow coupler with fittings to protect the flow and return elements, the circulation pump and the three-way jumper with motor, are built into the RTH module. Installation time is reduced to a few hours.

Air heating system APH

The combustion air is preheated with hot feed water and therefore less fuel is needed. At the same time, the cooled feed water lowers the boiler’s flue gas temperature.
