Expansion Tanks & Pressurisation Systems

Control of the internal pressure within heating, cooling and HVAC systems is critical to their efficient operation and longevity. Traditional expansion tanks allow air to become dissolved in the water which has implications on corrosion and sludge accumulation. Duraflex expansion tanks and pressurisation systems work differently, a diaphragm seals the interface between the two phases and prevents any interchange while maintaining control over the pressure and expansion. For high pressure or larger volume systems, the pressurisation is achieved using a separate expansion vessel and providing highly accurate control with any pressure changes kept to an absolute minimum.
