Expansion vessel for central heating systems
Composite Expansion Vessels for Heating Systems
Technical characteristics
- Expansion vessel for central heating systems
- Approved in accordance with pressure equipment guidelines 2014/68/EU
- Pressurized gas chamber
- Replaceable membrane
- Dimensions of top and bottom connectors may be changed on request
- Flow-through available on request
- With threaded connection, made from corrosion-resistant steel
Plastic-composite type expansion vessels are designed the way the water expands inside the membrane without contact with the vessel’s walls. There is also an air space between the membrane and the vessel which is acting as a thermal insulator. It can be designed in flow-through type on request.
- Up to 60%, fewer heat losses compared to diaphragm types, due to the minimized contact surface between warm water and vessel.
- Low heat losses due to minimum captured quantity of warm water.
- Low heat losses due to thermal inertia of a plastic-composite reservoir.
- No stagnant warm water - contamination prevention.
- Maintenance-free
- Limitless installation application; It can be installed in a moist environment, near the seaside, in basements, industrial space.
- The heavy-duty butyl membrane does not support the build-up of nutrients key to forming biofilms.
- Extended membrane lifetime. Lower elongation of our membrane provides less stress during operation.
Achieved benefits for end users
- Low energy bill
- Minimized maintenance costs
- Efficient system performance
- Clean and safe fresh water
- Prevention of Legionella or other bacteria
- Highly reliable heating system
- Smooth and safe operation
