Model AS Series - Aqua Saver Closed Loop Cooling Systems

From

0

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 90oF the unit can only cool down to 90oF.

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.
