LED - Recessed Plenum Access Cleanroom Luminaire with Overlapping Doorframe

CRUo-Plenum Access

The CRUo Plenum Access LED luminaire is a recessed lighting solution designed for environments that demand precision and reliability. Engineered for cleanroom applications, this fixture combines durability with advanced performance, making it ideal for ISO Class 3–8 spaces. Featuring an overlapping doorframe and triple gasket system, the CRUo ensures a secure seal for wet locations while maintaining IP65 certification. Its plenum access capability allows convenient above-ceiling entry without compromising the integrity of the cleanroom, offering unmatched flexibility for maintenance and installation.

Built for critical environments, the CRUo delivers exceptional lighting quality with narrow spectrum options available for specialized needs. High-efficiency LED modules provide consistent color performance across a range of color temperatures, including tunable white from 2700K to 6500K. With a lifetime rating of L90 beyond 60,000 hours, this luminaire minimizes downtime and reduces long-term costs. The design incorporates a smooth, impact-resistant acrylic lens sealed with RTV silicone, ensuring easy cleaning and contamination control. Combined with a robust housing of cold-rolled steel or optional stainless steel, the CRUo stands up to rigorous conditions such as 2500 psi washdowns and chemical exposure.

Installation versatility is another hallmark of the CRUo series. Compatible with 1" and 1.5" T-Bar grid systems and flanged ceilings, it supports universal mounting brackets for secure placement. The fixture meets NSF2 standards for splash and non-food zones, with optional certification for food zones. Electrical performance is equally impressive, featuring a programmable, dimmable driver with 0–10V control and optional DALI or Lutron compatibility. Emergency battery pack options and circadian technology further enhance adaptability for specialized environments. Every component is designed for serviceability from the room side, ensuring minimal disruption during maintenance.

For facilities prioritizing cleanliness and compliance, the CRUo offers a comprehensive solution. It is UL listed for wet locations, cleanroom classified, and compliant with CCEA requirements. Whether in pharmaceutical labs, biotech facilities, or healthcare settings, this luminaire delivers superior illumination while meeting stringent regulatory standards. With plenum access and advanced sealing technology, the CRUo is more than just lighting—it’s a critical component in maintaining controlled environments.
