Expansion Tank


Expansion Tank for Cars, Trucks and Heavy Vehicles

Elbostany has developed an excellent reputation for delivering high quality products for hot or chilled water HVAC systems. Every part that goes into our products is tagged and is traceable throughout the life of the product. To ensure international standards of quality, we have a team of certified professionals. As a result, we’re recognized for delivering a wide breadth of high quality pressure vessels that are cost competitive and delivered on a timely basis.
An expansion tank or expansion vessel is a small tank used to protect closed (not open to atmospheric pressure) water heating systems and domestic hot water systems from excessive pressure. The tank is partially filled with air, whose compressibility cushions shock caused by water hammer and absorbs excess water pressure caused by thermal expansion.
An expansion tank is also used in the cooling system of most internal combustion engines, to allow the coolant, the antifreeze and the air in the system to expand with rising temperature and pressure.

Pressure stabilization in water based mechanical systems such as booster installations, boiler systems, and chiller plants.
Product Description
Elbostany Expansion Tanks are designed to reduce tank sizes by up to 80% over standard designs. Expansion tanks use compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools.
Diaphragm or bladder tank designs isolate the expanded water from the pressure controlling air cushion – which is pre-charged at the factory and can be adjusted in the field to meet final system requirements.

Our Product Features

  • Lowest footprint
  • Space saving design for up to 80% reduced footprint over standard tank designs.
  • Low operating cost and risk.
  • Eliminates air ingress and dampens pressure transients (water hammer) for reduced system corrosion and stress, ultimately extending service intervals and overall system life.
  • Stabilizes system pressure, maintaining optimum levels of a critical operating parameter.
  • Reduces need for chemical treatment.
