Cooling Water Requirements; Water Cooled Condenser Table - Aircel VF-10 Installation And Operation Manual

Cooling Water Requirements (water cooled
condensing units)
Cooling water is required for water-cooled
refrigerant condensers (scfm rated model 100 and
up). The user is responsible for piping the water
to and from the condenser. The required water
flow rate depends on the water temperature. A
water-regulating valve (supplied with the dryer)
automatically adjusts the flow to compensate for
variation in water temperature, water pressure,

Notices:
• Water cooled condensers are pre-set at the factory for city water usage.
• Water regulating valve may need to be adjusted to other water supply conditions. Contact technical
support for assistance.
• Minimum water pressure is 25 psig for city water and 35 psig for tower water. Cooling water
pressures less than these minimums may reduce dryer drying capacity.
• Maximum water pressure is 125 – 150 psig.
