Hydropneumatic Tanks

Hydropneumatic tanks are ASME and non-ASME vessels that hold water and air under pressure. To provide efficient water supply, hydropneumatic tanks regulate system pressures to quickly meet system demand. The compressed air creates a cushion that can absorb or apply pressure as needed. Typical applications include booster pump, well water, sprinkler or irrigation application, or any application where a continuous flow of water is needed while regulating pump cycles. In a booster pump application, it can provide water to the system during periods of a no flow shutdown of the booster pump or it can provide water to replace leak loads. In a well water application, it can provide the desired volume of water required between the pump shut down pressure and the pump turn on pressure. In a sprinkler or irrigation pump application, the tank may provide a cushion to maintain necessary pressure so the jockey pump will not short cycle.

Bladder Hydro-Pneumatic Tanks - ASME

AAtanks ASME-code bladder and diaphragm style hydro-pneumatic tanks will be smaller in size than the plain steel hydropneumatic tank design and thus require less floor space. AAtanks designs utilize a heavy-duty butyl rubber barrier between the air and water which prevents water logging. The pre-charged hydro-pneumatic tank is virtually maintenance free.

Bladder Hydro-Pneumatic Tanks - Non-ASME

FX bladder style tanks are non-ASME code design. FX tanks will be smaller in size than the plain steel hydropneumatic tank design and thus require less floor space. The heavy-duty butyl rubber replaceable bladder is a barrier between the air and water which prevents water logging. The pre-charged hydropneumatic tank is virtually maintenance free. Sizes from 2 to 528 gallons. Standard design working pressure 150 PSI.

Heat Exchangers

AAtanks offers three heat exchanger designs: Plate and Frame, Brazed Plate and Shell and Tube. Flow rates range from 30-10,000 gallons per minute. Heat exchangers are manufactured to efficiently transfer heat between two fluids (gas or liquid) while keeping them separate. In typical HVAC installations, steam or hot water primary loops distribute heat from a central energy source out to secondary loops. Heat exchangers transfer heat from a system’s primary and secondary loops and can also serve as a separation device to reduce system costs. Applications include domestic water heating, radiant heating, district heating, pool heating, condensate cooling, air conditioning, snow melting, and more.

Separators

AAtanks offers 3 distinct groups of separators: Air Separators, Air & Dirt Separators and Solid Separators. Air separators are used to separate entrained air in water through forced flow patterns. Air & dirt separators are designed to eliminate entrained air and separate debris associated with start-up and maintenance of any hydronic system. Solid Separators are designed to remove entrained solids from a liquid system.
