EXPANSION SYSTEM

The Weiss Expansion System is mainly used with larger heating systems and district heating systems.

The expansion system is supplied as a complete system, consisting of vessels and control system, to maintain the operating pressure of the heating system.

A diffusion-tight plastic membrane prevents internal corrosion in the system. By protecting the water in the container from the effects of air and oxidation, corrosion is prevented.

A removable aluminum cover protects the membrane from dirt and debris and allows inspection of the expansion system during operation.

The container is equipped with clear plexiglass to display the water level. On the water level glass there are 4 level switches that control the automatic water filling. On the opposite side of the water level glass there is an overflow tube.

The safety equipment consists of a level control (water breakthrough protection).
