Closed Loop Fluid Cooler And Pumping Station
Our Water Saver Closed Loop Cooling System significantly reduces energy costs by removing heat from water cooled machinery. The process reduces temperatures to slightly above ambient, eliminates corrosion and contamination, and eliminates need for an outside water supply and sewer. This can produce significant increases in production efficiency and significantly lower your costs by cutting water usage. The closed-loop system eliminates the possibility of corrosion and contamination, and our system can be custom designed to your application for quick and easy installation and commissioning. It requires little or no maintenance.
Typical process cooling fluid (water with varying proportions of glycol) is circulated through the closed loop system by using pumps. Ambient air is sucked from the bottom of the Water Saver. This results in a steady flow of air around the tubes carrying the cooling fluid. With the use of thermally activated valve (optional) and an additional trim-cooler, temperatures very close to ambient and below can be achieved.
Next Air & Gas provides the choice of either a Single (PSS Series) or a Double (PSD series) pumping station. The typical pumping station package includes the pump, the starter, your choice of NEMA enclosure along with monitoring lights and On/Off switch. The entire unit is pre-piped and mounted on a skid. The PSD series comes with 2 pumps and separate control valves. These units come with standard of 230/460 voltage. Optional voltages are also available upon request.

- All units are UL & CUL and MEA – listed.
- All units are constructed of heavy-gauge, corrosion resistant galvanized steel for maximum casing rigidity. Multiple fan units are separated by full width baffles to prevent air bypass.
- This provides additional casing reinforcement.
- To enhance the tube life, all end panels, center supports, and partitions have collared tube holes.
- The fluid coils are constructed using seamless copper tubing on a staggered pattern. Tubes are mechanically expanded into continuous full-collared plate-type aluminum (or optional copper) fins for permanent metal-to-metal contact.
- Headers come equipped with vents and drains.
- All coils are factory pressure and leak tested at 400 PSI.
- Aluminum fans with painted steel hubs are dynamically balanced and factory tested before shipping to ensure quiet operation.
- Fan guards are designed from heavy-gauge, close-meshed steel wire with vinyl coating for maximum rigidity, long life and attractive appearance.
- Fan motors are heavy duty PSC or three phase open drip-proof type with permanently lubricated ball bearings and built-in overload protection. All motors are factory wired with leads terminating in a weather-tight enclosure located opposite the header end of the unit.
