CRL & CRR Recessed Cleanroom, Inset Door


The Tri-Seal CRL is designed to meet the toughest requirements in clean room and BSL applications. For use in horizontal or non-laminar air flow rooms, the enclosed and gasketed housing and one-piece door protect against infiltration of airborne bacteria. Die-formed edges on the door frame and the hole-free design of the housing prevent air exchange between the fixture and the plenum, allowing for re-lamping without contaminating the area. One-piece gaskets are included on lens and on door edge for easy replacement. The CRL is suitable for 9/16-inch, 1-inch and 1-1/2-inch T-Grid ceilings. It is UL/cUL listed for wet locations and IP 65 rated and manufactured in accordance with ISO 14644, NSF and Federal Standard 209E in a certified ISO 9001:2000 facility.
