February 26, 2013 – Rittal’s newly redesigned rain hoods allow fan cooling in any environment, boasts the company, including harsh chemical and washdown locations. The hoods are available in powder-coated carbon steel offering NEMA 3R and NEMA 4 protection. The powder-coated versions are RAL 7035 (light grey), blending in with colour and texture of Rittal’s line of industrial enclosures. The stainless steel version offers NEMA 4X protection. The surface of the rain hood is a #4 brushed surface matching the surface of Rittal’s stainless steel enclosures. Rittal’s Top Therm fans and filters provide CSA-certified NEMA 12 protection right out of the box, says the company. With the addition of a standard fan and filter rain hood, this protection can be increased to NEMA 3R, 4 or 4X.
