Hydro-pneumatic tanks are used to store potable water. When properly sized, these tanks are designed to maintain a potable water system within a specified pressure range. Typically used in water well systems, pressure booster packages, and industrial water accumulation applications.
Materials = Steel Shell, Heavy Duty Butyl Bladder
Maximum Pressure = 150 PSIG
Maximum Temperature = 200oF
Finish = Blue Powder Coat Exterior
Factory Pre-charge = 30 PSIG
Bladder tanks are required in a closed loop heating or chilled water HVAC system to absorb the expanding fluid and limit the pressure within a heating or cooling system. A properly sized expansion or compression tank will accommodate the expansion of the system fluid during the heating or cooling cycle without allowing the system to exceed the critical pressure limits of the system. The expansion or compression tank uses compressed air to maintain system pressures by accepting and expelling the changing volume of water as it heats and cools. Some tank designs incorporate a diaphragm or bladder to isolate the expanded water from the pressure controlling air cushion. As water is expanded, it is contained in the bladder preventing tank corrosion and water logging potentials. The pressure controlling air cushion is pre-charged at the factory and can be adjusted in the field to meet critical system requirements. This design and operation of this style of expansion tank allows the designer/specifying engineer to reduce tank sizes up to 80%.
Bladder tanks have a totally replaceable bladder. This tank must be equipped with large service openings and also allow the bladder to be replaced without having to remove the tank from its mounting.
Wessels type FX-Series Tanks are non-ASME replaceable bladder type pre-charged hydropneumatic tanks for residential and commercial well and water systems, booster systems, irrigation systems, etc. They are designed to deliver water under pressure between pump cycles to provide sufficient flow to meet demands. The water is contained in a butyl bladder. The exterior has a baked epoxy finish.
