Enclosure Drains

If an enclosure is not protected from moisture penetration, condensation can accumulate on the components inside the enclosure. Outdoor enclosures can be the most vulnerable to condensation, because they are often installed in environments that have high ambient humidity levels. Condensation can cause damage to electrical components, as well as to the enclosures themselves. Some potential hazards include: corrosion, short circuits, premature breakdown, mold and water drainage issues. Installing devices such as heaters, fans, air conditioners and dehumidifiers can help to manage an enclosure’s internal temperatures. These devices are typically regulated by thermostats and hygrostats, which automatically trigger the fans and heaters when ambient conditions reach a certain temperature or humidity level.

Hazardous location enclosures are specifically designed to isolate electrical components from hazardous locations. Hazardous locations are classified as areas where there is the possibility of explosion or fire because of the presence of ignitable or combustible gases, vapors, liquids, fibers or dust. Electrical equipment can be a potential source of ignition through sparks, equipment failure and high temperatures. Hazardous location enclosures are constructed to eliminate the potential for ignition of the atmosphere.

Hoffman Hazardous Location Breather Drains prevent moisture build-up within hazardous location enclosures while maintaining the UL Type rating. Drains are to be used when an enclosure is subject to fluctuations in temperature which can lead to the formation of condensation and a subsequent moisture build-up. The drains allow air within an enclosure to breathe with the surrounding atmosphere, preventing condensation and any potential damage to electrical equipment.

Hoffman H20MIT Vent Drains allow accumulated water to drain out of the bottom of an enclosure. They also function as an air pressure equalizer, reducing the harmful effects of temperature-induced vacuums that could pull moisture and water into the enclosure.
