Expansion Tanks & Pressurisation Systems

Expansion Tanks, Pressurization, and Backflow Prevention Systems play a critical role in hydronic heating and cooling systems.

Some key benefits include:

Maintaining optimal performance and longevity of the system.
Preventing corrosion and other gas-related problems.
Providing accurate control of pressure changes in large volume and/or high-pressure systems.
Ensuring a fully closed system, preventing the diffusion of pressured gas into the water.
Backflow prevention meets safety and regulatory requirements by preventing backflow of contaminated water into the potable water supply.

Expansion Tanks

Duraflex diaphragm expansion vessels are available in different pressure ranges and nominal volumes. Flat or cylindrical tanks are available depending on the application with a fixed diaphragm or replaceable bladder. These tanks require no electrical power for operation, making them a reliable and cost-effective solution.

Pressurisation Systems

Pressurization stations are an advancement of traditional diaphragm expansion vessels used in large volume and high-pressure systems. The key difference is the addition of a control unit that facilitates the transfer of expansion volume to a separate vessel. This precise control ensures minimal pressure fluctuations within the system.
