Auxiliary Condenser Fan
Commonly used in applications with high ambient temperatures, auxiliary condenser fans serve as a back up in the event of a failure of the primary condenser fan.
Because all of Specific Systems units incorporate a dual refrigeration circuit, the compressor, coils, and refrigeration lines are all built to be redundant. This allows the unit to operate at half capacity even if one refrigeration circuit fails. Similarly, the auxiliary condenser fan module is meant to back up the primary fan module.
Auxiliary condenser fan modules are available only on the 600 series InPac units. Units larger than these have condenser sections containing 2 or more fans, and it is improbable that all fan motors would fail simultaneously.
Specific Systems’ auxiliary condenser fans can be installed in a separate module or as part of a filtration package. The module will consist of the same fan and fan motor as the standard condenser fan.
The auxiliary fan will be configured in an opposite flow from the primary fan. In most cases, this will position the auxiliary condenser fan as a draw-through fan. The module itself consists of a housing, plenum, fan, and fan motor. The housing will be manufactured using the same 16-gauge steel as the main section of the unit with a matching coating, unless otherwise requested.
