ATEX453816SS61

Overview

The Hoffman ATEX453816SS61 is a stainless steel enclosure designed for hazardous area applications. It features an IP66 degree of protection and is constructed from AISI 316L stainless steel. The unit includes a hinged cover with a quarter-turn fastener mechanism and pre-installed mounting rails. Certified for use in Zone 1 and Zone 2 gas environments, it supports Ex d IIB+H2 and Ex tD A21 classifications. The enclosure measures 450 mm in height, 380 mm in width, and 160 mm in depth, providing substantial internal volume for component integration while maintaining structural integrity under harsh industrial conditions.

Feature Summary

• Constructed from corrosion-resistant AISI 316L stainless steel for durability in aggressive environments
• Certified for explosive atmospheres including gas and dust zones
• Provides IP66 protection against dust ingress and powerful water jets
• Features a hinged cover design with secure quarter-turn fasteners

Applications

• Installation in Zone 1 hazardous areas with explosive gas atmospheres
• Deployment in Zone 22 hazardous areas with combustible dust
• Protection of electrical components in offshore oil and gas facilities
• Enclosure for instrumentation in chemical processing plants

Procurement Notes

Verify that the specific order includes all necessary certification documentation, such as the EU-Type Examination Certificate and Declaration of Conformity, required for compliance in designated hazardous zones. Confirm that the cable entries and gland fittings selected are compatible with the IP66 rating and the specific ATEX/IECEx marking requirements of the installation site. Ensure the internal mounting configuration matches the intended component layout before finalizing procurement.

Selection Notes

Select this model when high corrosion resistance is mandatory due to exposure to saltwater or chemicals. Choose this enclosure for applications requiring certified protection against both explosive gases and dust. Consider the internal dimensions and available mounting rail space to ensure compatibility with the target electronic modules. Verify that the thermal dissipation requirements of the internal components can be managed within the sealed stainless steel environment.

Part Context

This part belongs to the Hoffman ATEX series of explosion-proof enclosures manufactured by Hammond Manufacturing, now operating under the Hoffman brand. These units are engineered specifically for the petrochemical, marine, and pharmaceutical industries where safety standards demand rigorous containment. The series utilizes heavy-gauge stainless steel to withstand mechanical impact and environmental corrosion while maintaining certified flamepath integrity.
