Air, from the air compressor, passes through the oil reservoir/separator,
where the oil is removed from the air stream. The air then passes from the
reservoir to the air injection point on the foam manifold. Air is also provided
to an auxiliary outside air powered accessory, if supplied.
Stainless-Steel X-type mixers provide a Hale-exclusive, superior mixing
action that combines the water, foam concentrate, and air inside the mani-
fold. The Hale CAFSPro provides quality foam right from the discharge
valve.
A water-to-oil heat exchanger provides the required cooling for the air com-
pressor lubricating oil. This cooler is fed from pump water, therefore you
must maintain pump water circulation in order to avoid overheating the air
compressor and/or pump. During operation, this is normally handled by
partially opening the tank-fill valve, or pump cooler valve. A thermal relief
valve is included with every CAFSPro system to warn against pump over-
heating.
Finally, a Stainless-Steel CAFS and foam solution piping manifold is
designed to give years of corrosion-resistant use. Manifolds are designed
for high flow, low pressure drop, and precision air and foam proportioning.
System controls are condensed into two easy to use push button operator
control display units:
❑ The Hale FoamLogix display (black), controls the foam concentrate
injection
❑ The Hale CAFSPro display (blue) controls the compressed air injection.
4.3 HALE CAFSPRO OPERATION
Flowing Compressed Air Foam
To make the operation of your Hale CAFSPro as easy as possible, Hale has
reduced the number of steps needed to create Compressed Air Foam.
When you first engage the fire pump, the tank-to-pump valve automatically
opens allowing tank water to flow into the fire pump. This water serves to fill
the pump and cool the air compressor, while removing one more steps for
the pump operator. The normal pump priming process may need to occur,
should the pump discharge gauge read zero (0), indicating a no-prime
condition.
Also, the foam and compressed air control system displays activate and
automatically turn ON the foam proportioner and readies the air compressor
to send air into the CAFS manifold.
