Cooling coils may be a viable solution when chilled water is already available at a site or when the operator requires a greater degree of cooling than is possible with evaporative coolers. Pneumafil offers integrated systems that include coils, housings, structural verification, supply and return piping and installation.

Some points to consider:

• For every degree F that the engine’s compressor inlet temperature is lowered, power output increases by about 0.33%.

• Typically, coils can provide up to 45 degrees F of air cooling, even in high-humidity environments where evaporative coolers do not work well.

• Coils require a source of chilled water

• Coils add more pressure drop to the system than do evaporative coolers.

• Coils condense large amounts of water that must be drained from the system.

• Like evaporative coolers, coils systems require eliminators to prevent water carryover.

• Coils add weight and may require structural enhancement of the support system.
