Product Introduction

The explosion-protected cleanroom luminaire encloses the LED driver and connection terminals within a robust cast or fabricated metal body. A thick glass or impact-resistant lens is retained by a bolted sealed frame, and incoming power passes through a matching threaded hub. The room-facing surfaces are simplified and coated or stainless so the fixture can be cleaned without exposing flame-path or electrical joints.

Key Features

A rigid metal body protects the driver and terminal chamber from impact and enclosure distortion.

Threaded cable hubs maintain the intended protection at each wiring entry.

The retained lens frame resists accidental opening during cleaning.

External cooling fins are minimized or positioned away from the primary wipe face.

Color-coded terminals and a separate wiring chamber simplify controlled servicing.

Customer Product Concerns

Hazardous-area protection and cleanability can conflict when deep cooling fins, open glands or rough castings face the controlled room.

A general industrial Ex light has deep fins that are difficult to sanitize.The selected cleanroom configuration presents a simplified smooth room-facing enclosure.

An unmatched cable gland compromises the protected connection chamber.Threaded entries use glands selected for the cable and enclosure arrangement.

Thin lens frames distort when bolts are tightened unevenly.A rigid retained frame distributes clamping load around the thick optical window.

Maintenance can mix power wiring with the optical chamber.A segregated terminal compartment limits access to the connection area.

Typical Applications

Solvent-handling cleanroomsHazardous compounding suitesBattery manufacturing dry roomsFine-chemical controlled areas
