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/stops 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
