The Balston Cabinet Dryers are designed specifically for wash down areas in meat and dairy plants to eliminate moisture and condensation inside electrical control panels. The system includes a filter and a hollow fiber membrane module can effectively reduce the humidity inside the cabinet to 10% or less, minimizing the possibility of moisture. In contrast to other approaches (e.g. the use of light bulbs, heaters or vortex coolers), the dryer addresses the source of the problem condensation caused by high humidity inside a cold electrical enclosure. The units can withstand chemical wash downs and require no electricity and simple annual maintenance.
