HDW0553921

Overview

The nVent HOFFMAN HDW0553921 is a wall-mount enclosure constructed from 304 stainless steel, featuring hygienic design principles for sanitary environments. It measures 552 mm in height, 390 mm in width, and 210 mm in depth. The unit provides IP66, IP69, and IP69K ingress protection ratings alongside NEMA 4X, 12, and 13 classifications. A 30-degree sloping roof facilitates liquid drainage, while surfaces are self-draining to prevent pooling.

Feature Summary

• Hygienic design with self-draining surfaces and a 30-degree sloping roof for effective liquid management
• Constructed from 304 stainless steel with pre-grained finish for durability in corrosive or washdown settings
• Sealed by a one-piece removable blue silicone gasket with molded corners to ensure environmental integrity

Applications

• Sanitary and washdown applications in the food industry
• Environments requiring high-pressure cleaning protocols
• Installation where corrosion resistance and hygiene standards are mandatory

Procurement Notes

Verify that the specific order matches part number HDW0553921, as the HDW series includes multiple dimensions and material variants. Confirm that the required ingress protection rating aligns with site conditions, noting this model supports IP66/69/69K. Ensure mounting infrastructure accommodates the specified 552x390x210mm footprint and weight. Check if additional accessories like DIN rails or internal components are included or require separate procurement based on project specifications.

Selection Notes

Select this model when hygienic compliance and robust corrosion resistance are primary requirements. The 304 stainless steel construction offers superior performance compared to carbon steel alternatives in wet or chemically exposed areas. The sloping roof design specifically addresses liquid accumulation risks common in washdown zones. Consider this option over standard enclosures if regulatory standards mandate seamless, cleanable surfaces without crevices for bacterial growth.
