Cleanroom Doors

Choosing the correct door system is a major factor in maintaining the delicate balance of a cleanroom environment. If a cleanroom door does not function correctly, the cleanroom could fail to meet the relevant standards and be exposed to a high risk of contamination.

Cleanroom doors are a crucial part of cleanrooms and are responsible for sealing the controlled environment. We offer cleanroom swing doors, cleanroom sliding doors and cleanroom hermetic sealing doors.

The ISO standard 14644-1 defines a cleanroom as: “a room in which the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimise the introduction, generation, and retention of particles inside the room and in which other relevant parameters, e.g. temperature, humidity, and pressure, are controlled as necessary”.

The cost of air control in a cleanroom can be comparatively high. The energy requirement of HVAC systems usually amounts to 50-75% of electricity consumption in a clean production space, due to the high airflow rates needed for particular ISO classes. However, when a door is opened, a significant exchange of air (with that of the outside air) will take place. This can affect the cleanliness of air within the room until such time that the HVAC can recirculate and clean the air again.

Cleanrooms that have hermetic sliding doors can give consistent and fully predictable sealing and air leakage control over long periods. Hermetic sliding doors have a frame mounted seal that, along with special indentations in the track, uses the door’s own weight to seal perfectly against the frame and also the floor.

Hygiene, secure sealing, minimising pressure drops, protecting against contaminants and drafts, reducing energy costs, improving user safety and ease of cleaning; these are just some of the key issues that address.
