Expansion Vessels

Our range of expansion tanks are available in three styles: horizontal, vertical and pipeline mounted. These tanks are designed to facilitate the pressurisation of hydraulic systems and enable a constant supply throughout the system on both heating and potable water systems.

Applications
The GLV range is suitable for many types of system:- domestic, commercial, industrial and agricultural. The membrane, made from food grade material (EPDM), is perfectly acceptable for use on potable water supplies and is approved by the WAC. With a temperature range of -10ºC to + 100ºC the tank may be used on domestic hot water supplies as an expansion vessel. Other typical applications include -water treatment, pressurisation systems, booster sets, reverse osmosis and as an aid to reduce water hammer.
