Cleanroom Doors

Cronax Cleanroom Doors are designed to meet the stringent requirements of controlled environments, ensuring air-tightness, hygiene, and durability for industries such as pharmaceuticals, biotechnology, electronics, healthcare, and food processing. Engineered with precision, these doors help maintain the integrity of cleanrooms by minimizing air leakage, particle accumulation, and cross-contamination risks.

Manufactured using stainless steel, galvanized steel, or high-pressure laminate (HPL) panels, our cleanroom doors feature smooth, non-porous surfaces that are easy to clean and resistant to chemicals, microbial growth, and wear. They can be customized as single or double-leaf, hinged, sliding, or hermetic types, depending on the facility’s needs. With high durability and flush design that eliminates dust traps, they ensure maximum hygiene and operational safety. These doors are reliable solution for contamination-free environments, offering a perfect balance of functionality, safety, and long-term performance.

Control Interfaces	Touchless activation via infrared sensor, access control integration (RFID, code), or manual push panels with sealed enclosures.
Safety & Monitoring	Obstruction detection, safe soft reverse during closing, status feedback to cleanroom monitoring systems.
Emergency Override	Manual breakout capabilities in automatic doors for egress during emergencies; failsafe door brake ensures controlled closure.
Integration	Compatible with facility management systems, HVAC interlocks, fire alarms, and cleanroom pressure control systems.

Surface Finish	Seamless stainless steel (matte or mirror), anti-static HPL, or wipe-clean powder coatings in cleanroom color palette.
Color Options	Standard in cleanroom-friendly tones (white, light grey); full RAL or custom matches available on request.
Vision Panels	Flush-mounted tempered or safety glass with integral gaskets, flush trims, and zero-edge design to reduce particle collection zones.
Sealing Packages	Double-lip sealing with magnetic closure plus drop-down bottom seal for superior exclusion of dust and airborne contaminants.
Acoustic & Thermal	Optional acoustic-rated variants up to Rw 35 dB; thermal-rated variants available for conditioned zones.
Accessories	Touchless handles, antimicrobial push plates, pressure display units, kickplates, and hygiene-certified finishes.
