Sloped Top Enclosures


EST SERIES
NEMA TYPE 4X,12,13

Water and Dust Tight Stainless Steel Sloped Top Enclosure

 

Application


Ralston’s EST 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 EST series 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).

 

Construction

 

All EST enclosures are made from 1.5mm #304 stainless steel. All seams are continuously welded and ground to a smooth finish. Each enclosure comes complete with grounding studs, and  a removable 2mm (EST) galvanized back panel mounted on M6 weld nuts.

The 120° 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.

 

The top of the body is equipped with a sloping roof with a slope of between 8° and  30°, giving a 20mm  overhang to remove liquids away from the door opening.  The sloped top does not allow liquid pooling on the top of the enclosure, eliminating a potential dangerous situation of water dropping into the enclosure once the door is opened.

 

Finish


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

 

Standards


The EST are 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 EST is CE, UL and cUL for Canada and the USA.
