AISI 316L Stainless Steel Enclosures for Explosion Hazard Zones

Terminal boxes made of electropolished AISI 316L stainless steel are designed for safe use in environments at risk of explosion. Their construction meets stringent international standards such as ATEX and IECEx, ensuring resistance to explosions and the ability to prevent ignition of explosive atmospheres. Stainless steel AISI 316L provides exceptional corrosion resistance, making these enclosures an ideal solution for challenging industrial conditions.

Elimination of Ignition Sources in Ex Junction Boxes

These boxes are equipped with grounding, eliminating the risk of electrification. Additionally, the precise selection and arrangement of components inside the enclosure prevent heat generation, which is key to ensuring safety in Zones prone to explosions. Each box model is designed and manufactured to order, allowing for customization to meet individual client needs.

Resistance to Mechanical Damage

Technical solutions preventing mechanical damage have been applied in the enclosures, increasing their durability and reliability. The body and cover of the boxes, with a thickness of 1.5 mm, guarantee high mechanical strength, and the available options for mounting Ex connection clamps allow for their flexible use in various industrial applications.

Application of Ex Stainless Steel Enclosures

HTB1S terminal boxes are widely used in various industrial sectors, including lighting control, as battery enclosures, alarm centers, or control boxes. They are ideal for operation in challenging conditions, such as in the chemical or pharmaceutical industry, due to their corrosion resistance and adaptability to specific technical requirements.
