Regular washdowns are a must for many different kinds of facilities. From food service to livestock processing to manufacturing, cleaning with pressurized water is a standard way to keep facilities clean and sanitary. However, sensitive electrical components can be easily damaged by hose-directed water, potentially leading to equipment problems and unsafe situations.
To prevent damage to electrical components during a washdown, it’s important to have these components protected by a washdown enclosure. Polycase offers numerous waterproof enclosures rated to protect against washdowns, including models that also guard against corrosion and submersion.
First, let’s take a look at the protective features a washdown enclosure should offer. Then, we’ll talk about the easiest way to tell if an enclosure is rated to protect against washdowns–by looking at its NEMA or IP ratings. Finally, we’ll examine some of the many options that Polycase offers to protect your most sensitive electrical equipment.
When shopping for a washdown enclosure, there’s one feature to look for above all others: a waterproof gasket seal. Gasket seals, located inside the enclosure, are typically made from silicone or other durable rubber materials. They close the tiny gaps of the enclosure’s seams, keeping out water and other liquids (along with dust and dirt). Many different designs for gasket seals exist, but the most important thing is that they meet NEMA or IP specifications (described in the next section).
Although gasket seals are the most critical feature to look for, other design elements can also improve an enclosure’s performance in washdown conditions. These include:
To learn whether an enclosure is designed to keep your electrical components safe from pressurized water jets, look at its NEMA or IP rating. These rating systems are both designed to keep enclosure buyers informed about an enclosure’s protective features, including whether it’s safe for use in facilities that have regular washdowns.
When examining an enclosure’s ratings, look for the following:
