Single Door Stainless Steel Enclosure

NEMA TYPE 4,4X,12,13

Water and Dust Tight Stainless Enclosure



Ralston’s EWSS series enclosures are designed to provide protection indoors and outdoors, against dust, dirt, oil, and water for items such as: electronic and electrical controls, instrumentation systems, pneumatic, hydraulic and machine controls. The EWSS is designed for use in such areas as dairies, breweries and the food industry where they are subject to frequent high pressure hosing and generally wet conditions (Not submersible).



All EWSS enclosures are made from 1.5mm and 1.9mm #304 or #316 stainless steel. All seams are continuously welded and ground to a smooth finish. Each enclosure comes complete with grounding studs, and a removable 2mm galvanized back panel mounted on M8 weld nuts.


The 130° opening door is easily removed by pulling the removable hinge pins from the hidden hinges to allow right or left hand opening. The door is sealed with an extruded one-piece polyurethane gasket and is secured closed with chrome plated 3mm DIN type quarter turn latches.



Outer body and door of the EWSS has a 240s pre-grained (average 0.5 micron) fine finish for less attachment of chemicals and bacteria to the enclosure surface.  Interior mounting plate is galvanized.



The EWSS is built to the requirements of IP66, NEMA Type 12 for industrial use, 13 for oil and dust tight and to 4,4X for water tight and corrosion resistance.

The EWSS is CE, UL and CSA for Canada and the USA.
