The image above shows an electrical panel located over a belt press machine.  Belt press machines can be used in a variety of mechanical separation applications, from juice manufacturing to de-watering of grains, and even algae extraction.  The use in this application, however, was to assist in the removal of liquid from styrene via multiple “wedge zones” which force the styrene between an upper and lower belt, applying increasing pressure and forcing the liquid from the styrene roll.

The Plant Manager of the facility which uses this cabinet contacted EXAIR in search of a solution to provide cooling for this enclosure, and wanted to know if we could also provide some means to provide a constant ventilation as well.  We discussed the merits of the Cabinet Cooler in terms of cooling power, and also discussed our Non-Hazardous Purge Cabinet Cooler systems which provide a constant feed of 1 SCFM of compressed air into an enclosure.  This slight airflow into the cabinet provides a slight positive pressure which further helps to prevent any dust from entering the cabinet.  For older cabinets with potentially weakened seals, these systems can provide an added level of protection against harmful dust in the ambient environment.

After sending a Cabinet Cooler Sizing Guide and determining the proper model number (NHP4825), the customer asked about lead time.  They said that the machine was intermittently shutting down and they needed something FAST.  I informed them that EXAIR Cabinet Coolers ship from stock and we can even ship UPS Next Day Air if need be.

Knowledgeable engineering support coupled with a shoe-in solution and on-the-shelf availability got this application under control quickly.  If you’re having a similar experience with your electrical control panels, contact EXAIR’s Application Engineering department for a similar solution experience.
