- For potable water, pressure booster systems with or without flow-through
- With threaded connection, made from corrosion-resistant steel
Plastic-composite expansion vessels for potable water
Potable water systems must be supported by expansion/pressure vessel that stabilizes the hydronic system operation, and must assure water cleanness. The flow-through type is the best option in this case. Bladder type of potable water expansion vessels are also available.
- Reduces start/srtops of the driving pump , saving energy, maintenance costs and improving lifetime of the pump.
- Ensures constant water flow, even in case of pressure fluctuations.
- Water just flows through this vessel, without stagnation, and keeps its primary quality.
- Absorbs water hammers
- Ensuring smooth operation, protecting other system components.
Achieved benefits for end users
- Efficient system performance
- Clean and safe fresh water
- Prevention of Legionella or other bacteria
- Highly reliable hydraulic system
- Smooth and safe operation
