Horizontal type Hydropneumatic Tanks basically contains both water and air under pressure. These Hydropneumatic Tanks allow the compressed air to act as a cushion that can exert or absorb pressure as required. These Hydropneumatic Tanks help to regulate proper system pressure range, both necessary for the efficient operation of a water supply system. Horizontal type Hydropneumatic Tanks are widely used in large capacity pumping systems as buffer tanks as well as in water systems and fire protection systems.
