LED - Recessed Plenum Access Cleanroom Luminaire with Inset Doorframe

CRUi Plenum Access

CRUi Plenum Access Cleanroom Luminaire is a high-performance recessed lighting solution engineered for critical environments where illumination, cleanliness, and serviceability are equally important. Designed specifically for cleanrooms, laboratories, pharmaceutical facilities, healthcare spaces, biotechnology environments, and food processing applications, CRUi combines a fully integrated plenum access panel with certified cleanroom lighting performance. The recessed inset door design creates a smooth, sealed ceiling appearance while providing convenient access above the ceiling without the need for a separate access panel. Certified for ISO Class 3-8 cleanrooms and rated IP65, CRUi helps maintain environmental integrity in contamination-sensitive spaces.

The CRUi series is built with a precision-formed, seam-welded, hole-free housing that supports stringent cleanliness requirements and long-term durability. A triple-gasketed sealing system protects against dust, moisture, and contaminants, while the inset access door completely covers the fixture flange for a clean finished appearance. The sealed door is secured with captive stainless steel fasteners and chemical-resistant gaskets, helping facilities maintain compliance with demanding operational standards. Certified for wet locations and capable of withstanding washdown conditions up to 2500 psi, CRUi is well suited for environments that require frequent cleaning and sanitation procedures.

High-efficiency LED modules deliver consistent performance with excellent color control, long life, and energy efficiency. Available in 3000K, 3500K, 4000K, and 5000K color temperatures, the luminaire also offers tunable white technology ranging from 2700K to 6500K. For facilities requiring narrow spectrum lighting, optional red and amber LED arrays are available either independently or combined with white LEDs to support specialized applications and process-sensitive environments. With color consistency maintained within 3 SDCM and an L90 lifetime exceeding 60,000 hours, CRUi provides reliable illumination while reducing maintenance requirements.

Designed to simplify installation and maximize flexibility, the fixture accommodates both flanged ceiling installations and standard T-bar grid systems through its universal mounting design. Multiple housing materials, including painted steel, stainless steel, and aluminum, allow the luminaire to meet the requirements of corrosive, sanitary, and controlled environments. In addition to supporting plenum access, the fixture carries certifications including UL wet-location listing, NSF2 recognition, IP65 protection, ISO 3-8 cleanroom classification, suitability for Biosafety Levels 1-3, and compliance with CCEA requirements. Optional NSF Food Zone certification further extends its suitability for regulated food manufacturing applications.

By combining certified cleanroom lighting performance with integrated overhead access, the CRUi Plenum Access Cleanroom Luminaire helps reduce ceiling clutter, streamline maintenance activities, and support environmental compliance. It is an ideal solution for facilities seeking dependable illumination, contamination control, and practical access to building services above the ceiling while maintaining a clean, professional appearance.
