Operation

4.Air flow rate: Reducing air flow through the fluid cooler causes the cold process fluid temperature to rise. This is the recommended method by which to control leaving process fluid temperature.

If your fluid cooler is equipped with a single-speed motor, the motor may be shut off when the process fluid temperature becomes too cold. This will cause the process fluid temperature to rise. When the fluid temperature then becomes too warm for your process, the motor can be restarted.

Caution

When operating in this mode care must be taken not to exceed a total

fan acceleration time of 30 seconds per hour.

Fan cycling limits: From a dead stop, determine the number of sec- onds it takes the fan to arrive at full speed. Divide this number into 30 to determine the allowable number of starts per hour. Considering the normal fan and motor sizes utilized on MH Fluid Coolers, anticipate that approximately 4 to 5 starts per hour are allowable.

If your fluid cooler is equipped with a two-speed motor(s), you will enjoy greater opportunity for process temperature control. When the process fluid temperature becomes too cold, switching the fan to half- speed will cause the cold process fluid temperature to rise—stabiliz- ing at a temperature a few degrees higher than before. With a further reduction in fluid temperature, the fan may be cycled alternately from half-speed to off—subject to the same constraint of 30 seconds of allowable acceleration time per hour as outlined above.

Wintertime Operation:

The Marley film-fill system used in the MH Fluid Cooler has air entrance louvers that are molded as an integral part of the fill. This feature makes these fluid coolers very forgiving of cold weather operation, even at the low temperature and reduced load conditions encountered in low temperature applications. Nevertheless, during operation in subfreezing weather the op- portunity exists for ice to form in the colder regions of the fluid cooler.
