 Expansion system
Application
Expansion system is an automatic
device for maintaining the pressure in the warm and hot water system of heating.
The device enables the reception of water surplus, which appears during the water warming
in the installation of central heating. It also enables replenishment of central heating
installation during cooling or water shortages in the installation because of the system
losses and bottom blow of boilers or heat exchangers.
The device can be applied in the systems of
the warm and hot water installation of the central heating with capacity goes from 350 kW
up to 24 MW in 11 sizes and 14 designs with operating pressure 5 bar.
In accordance with the DIN 4751
requirements, Part 2 for installation of capacity more than 350 kW the expansion system of
this type is obligatory for use.
Device characteristics:
- automatic work
- reliability in operation
- noiseless
- small dimensions
- easy installations
- simple for transport
- minor costs of maintenance
- guarantee is valid 12 months after putting
into operation or maximum 15 months after delivery date.
Production range
