LED Recessed Cleanroom Top Access Walkable with Overlapping Door Frame

CRTA

The CRTA series is a recessed cleanroom lighting solution rated for 800lbs static load, delivering exceptional strength for demanding environments. Designed for installation in walkable composite ceilings, this fixture ensures durability and reliability where structural integrity is critical. Its overlapping gasketed door frame and sealed lens prevent dust, liquid, and vapor penetration, making it ideal for cleanrooms, laboratories, and controlled spaces that require stringent contamination control.

With its top access walkable design, the CRTA troffer allows maintenance from above without disrupting cleanroom operations. Reinforced structural brackets and TIG-welded corners provide the strength needed for ceiling walkability, while convenient lift handles simplify handling during installation and servicing. Tested to ASTM-E72 and E2322 standards, this fixture guarantees superior load resistance and long-term performance.

The CRTA fixture is optimized for cleanroom lighting applications, meeting ISO Class 3–8 standards. Its high-diffusion acrylic lens ensures uniform illumination, while LED modules maintain color consistency within 3 SDCM. Available in multiple color temperatures (3000K–5000K) and CRI options (80 or 90), the fixture supports rigorous cleaning practices thanks to its IP65 rating and NSF2 certification. With recessed mounting and no roomside hardware, the design minimizes contamination risks and simplifies compliance with cleanroom protocols.

Advanced LED technology powers the CRTA series, delivering high efficiency and a lifetime L70 exceeding 60,000 hours. A programmable, dimmable driver (0–10V) ensures precise control and energy savings, while emergency battery backup options provide added security. The fixture’s gloss white antimicrobial finish enhances hygiene, and optional stainless steel doorframes offer durability in harsh conditions. Whether for pharmaceutical, biotech, or electronics manufacturing, this solution delivers reliable, high-performance recessed lighting tailored to critical environments.

Every CRTA fixture is ETL-certified for wet locations, IP65-rated for dust and water resistance, and backed by a 5-year limited warranty. Its robust construction and cleanroom compliance make it a trusted choice for facilities prioritizing safety, efficiency, and longevity.
