HARDO explosion-proof terminal boxes are an excellent alternative to well-known global manufacturers. They are certified for use in zones 1, 2, 21 and 22. We supply all control stations with accessories according to the investor’s requirements.

Electro-polished

Manufactured from high quality stainless steel that is electro-polished for a highly corrosion resistant “Chromium enriched“ surface. This multi certified enclosure is available in different sizes and depths, each with the facility for many configuration possibilities for a multitude of applications. Using the highest quality materials, unique design benefits and precision manufacturing the N-TB range is the benchmark in heavy-duty gauge enclosures of its class. An integral drainage channel prevents liquids or other solids contaminates from running in or falling into the enclosure when the door is opened, and to minimise gasket path contamination.

Degree of protection

The high integrity „one piece“ sealing gasket for superior ingress protection (IP) of 66 and excellent recovery and re-sealing properties for continuous environmental protection. There is an option for the mounting of up to four 3 mm thick gland-plates on each side in 4 possible combinations of 1, 2, 3 or 4 gland-plates. All units are sealed to IP66 by a high integrity Silicon gasket and secured by stainless steel bolts into blind inserts.
