AquaSavers

Aqua Saver series closed loop cooling systems

AS = Aqua Saver closed loop cooling systems

Pioneer's Aqua Saver Closed-loop systems eliminate water loss by evaporation and algae & bacteria problems. The Aqua Saver uses the ambient temperature to lower the the fluid temperature. If the ambient temperature is 90^oF the unit can only cool down to 90^oF.

AquaSaver Specifications

The packaged, single-skid, closed-loop system shall include…

Air-cooled Heat Exchanger

High-efficiency heat exchangers shall cool larger water flows with minimum pressure drop by using atmospheric air as the cooling medium. The cooling capacity to HP ration shall be maximum.

Multi-circuit design shall have minimum pressure drop.
Coil design shall allow even air distribution and therefore minimum pressure drop.
For longevity materials shall be:
Coil: aluminum fins, copper tubes
Legs: galvanized steel
Housing: aluminum
Motors shall be direct-drive, amply sized to handle designed load conditions.

Specially designed heavy-gauge aluminum blade fans shall be statically and dynamically balanced for vibration-free operation. Fans shall be protected with coated safety guards. Number of fans shall be _______, each _______ H.P. Fans shall cycle to save energy and provide temperature control. All connections shall be factory wired to the junction box on the housing exterior or to the control panel. The heat exchanger shall be Pioneer model___________

Simplex Pumping Station

Unit shall include a pump, expansion tank, starter, NEMA 1 control panel, power-on light, on/off switch, water-out pressure gauge, and water-out temperature gauge. The pumping station shall be Pioneer model__________

Trim Cooler

The Trim Cooler shall be tube and shell design. Tubes, shell and baffles shall be of rust-free materials: copper and/or brass. The trim cooler shall be Pioneer model______________

Options:

· Duplex Pumping Station (in lieu of Simplex)

Unit shall include two pumps, an expansion tank, two check valves (one for each pump), starters, NEMA 1 control panel, power-on light, on/off switch, water-out pressure gauge and water-out temperature gauge. Additionally, each pump shall be piped with two isolation valves, one on the suction side and one on the discharge side, so that either of the pumps can be removed from the piping system and replaced without having to shut down the system. All components shall be prepiped, wired and mounted on a skid.

The Duplex Pumping Station shall be Pioneer model _________________
