Hermetic Doors
Cronax Hermetic Doors are specially designed to provide an airtight seal, ensuring controlled environments in critical areas such as operating theatres, ICUs, laboratories, cleanrooms, and pharmaceutical facilities. Built with precision-engineered mechanisms, these doors prevent the entry of contaminants, dust, and airborne particles, while maintaining the required air pressure differential inside the room. Constructed from high-quality stainless steel, galvanized steel, or HPL panels, our hermetic doors feature smooth, seamless surfaces that are easy to clean and resistant to microbial growth.
They are available in both manual and automatic sliding systems, with specially designed seals that ensure up to 99% airtightness when closed. With options for vision panels, lead lining (for X-ray protection), and fire-rated performance, Cronax Hermetic Doors can be tailored to suit diverse medical and industrial applications. Their silent and smooth operation, combined with durability and hygiene-focused design, makes them an essential solution for infection control and contamination-free zones.
