HOFFMAN A-16P16SS Stainless Steel Enclosure 406×406×152mm

The nVent HOFFMAN A-16P16SS is a 316L stainless steel NEMA 4X / IP66 enclosure measuring 406 mm × 406 mm × 152 mm (16" × 16" × 6"), engineered for the protection of electrical components, instrumentation, and control equipment in corrosive, washdown, and coastal environments. Fabricated from 316L austenitic stainless steel — the marine-grade alloy containing 2% molybdenum for superior resistance to chloride pitting corrosion — the A-16P16SS carries a 2000-hour salt-spray test rating per ASTM B117, making it one of the few commercially available enclosures certified to survive the chloride-rich coastal atmosphere of Saudi Arabia's Arabian Gulf coast and Red Sea shoreline installations. The NEMA 4X rating guarantees protection against windblown dust, rain, splashing and hose-directed water, and corrosive agents, covering all outdoor installation scenarios encountered in Saudi Arabia's industrial and coastal environments.

The coastal industrial facilities of Saudi Arabia present some of the world's most demanding enclosure corrosion environments. Along the Eastern Province Arabian Gulf coast — where ARAMCO's Ras Tanura, Jubail, and Al Khobar facilities are located — the combination of high humidity, salt-laden sea breeze, and hydrogen sulphide from gas processing operations creates an atmospheric corrosion environment classified as Category C5-M (very high marine) under ISO 9223, the most aggressive corrosion class defined by the standard. Standard galvanised or mild-steel enclosures in this environment exhibit visible rust within weeks and structural corrosion within 12–18 months; 304 stainless steel performs better but pitting corrosion from chloride ions penetrating the passivation layer limits its service life to 5–10 years without maintenance. The HOFFMAN A-16P16SS's 316L alloy and 2000h salt-spray certification specifically addresses this challenge, providing documented evidence of corrosion resistance that satisfies ARAMCO vendor approval requirements and SABIC material qualification standards for coastal site installations.

For NEOM's coastal infrastructure — particularly the linear city The Line's utility corridors, Sindalah island resort, and Aqaba Gulf-facing installations — where seawater proximity and high humidity are permanent conditions, the HOFFMAN A-16P16SS is the go-to specification for junction boxes housing field instrument terminals, motor starter combiner panels, and ELV system interface cabinets. The enclosure's standard mounting feet and DIN rail mounting kit allow rapid installation of terminal blocks, miniature circuit breakers, and signal conditioners in a weatherproof field enclosure without custom fabrication. Desalination plants at SWCC's Jubail facility and MARAFIQ's Yanbu operations specify HOFFMAN 316L enclosures for their seawater pre-treatment and post-treatment chemical dosing control panels, where brine mist and chlorine off-gassing rapidly attack standard enclosure finishes.

Razz Middle East stocks the HOFFMAN A-16P16SS along with a comprehensive range of HOFFMAN stainless and GRP enclosure accessories including back panels, DIN rails, cable entry plates, padlocking handles, and window kit inserts. We supply complete enclosure solutions — configured, drilled, and fitted with internal components — reducing on-site installation time for instrument loops and junction panel applications. Our engineering team provides enclosure selection guidance aligned with IEC 60529 IP and NEMA ratings required by ARAMCO, SABIC, and NEOM electrical specifications, and we prepare vendor data documentation packages for project material requisitions.
