RECO hydro-pneumatic tanks are designed to store both water and compressed air. Without an internal bladder to separate the two, the compressed air is in direct contact with the stored water and acts to either absorb or exert pressure on the water.
NOW IN STOCK: HYDRO-PNEUMATIC TANKS SIZES 1,000 – 5,000 GALLON. READY TO SHIP AT TIME OF ORDER. Custom pressure ratings and tanks available up to 35,000 gallons
RECOhydro-pneumatic tanks are used in well water systems, fire protection systems, or as buffer tanks in large pumping systems to improve system performance in several ways. For pressurization the RECOhydro-pneumatic tanks maintains a minimum positive pressure throughout the system. This enables a rapid response to demands for water without having to continuously run the system pumps. The RECOhydro-pneumatic tanks also dampens pressure fluctuations and any hydraulic shock (water hammer) caused by pump cycling or rapid valve closures. This helps extend the life of those components.
The RECOhydro-pneumatic tank can also serve as a back-up safety device, supplying water for critical needs during unplanned power outages. All tanks include (2) connections for a sight glass and separate relief valve, air, inlet, vent, and drain connections at no additional charge. A 12” x 16” manway is also included as standard.
RECOhydro-pneumatic tanks are designed for horizontal use, above or below grade, with storage capacities from 1,000 to 35,000 gallons. Their interiors are epoxy lined as standard to prevent corrosion, and they work best with an air cushion of about ¼ of the tank volume.
