Cleanrooms Inter Lock Door Systems

Interlocking systems are designed to provide a safe, efficient and convenient means of opening and closing doors in a controlled environment such as a cleanroom. In cleanrooms designed with multiple entry points or interconnected rooms, the doors can be equipped with an interlock door system to prevent a sudden loss of positive pressure and the resulting influx of air due to personnel inadvertently opening too many doors at once.

When one of the interlocked doors is open, all other interconnected door locks will prevent personnel from opening any of the other doors. This feature will prevent cross-contamination in high-volume production facilities that utilise multiple cleanrooms with varying levels of cleanliness.

An interlock door system prevents loss of pressure and allows the ventilation and air purification systems to operate optimally.

At Total Clean Air, we are leaders in the design and manufacture of state-of-the-art interlock systems for cleanrooms as well as any other critical area that requires door access control. Our interlock door systems are available for installation as part of a door package or separately, to existing doors. Our designs are cost-effective and will provide safe, functional and user-friendly control to any facility.

How Interlock Door Systems Operate in a Cleanroom Environment

Interlock door systems for cleanrooms are used in a variety of industries worldwide. An interlock can take many forms. In its simplest form, an interlock comprises two doors, each opening into a separate space, with an airspace between them.

The functional concept of an interlock is to prevent two doors from being opened at the same time, therefore preventing air from passing from one space directly into the other. Interlocks are typically used in cleanroom environments and manufacturing areas to preserve air quality and prevent outside airborne particulates from entering process areas.

The interlock system will arrive pre-programmed at your premises, and the status of the interlocked doors can be monitored using a display located on the cleanroom control panel.

In the event of an emergency or power outage, the interlocks will be deactivated and the sliding doors will swing open if pushed forcefully outward. Common areas in cleanroom and production environments using interlocks are personnel entrances and exits, gowning and de-gowning areas, and material transfer airlocks.

Benefits of Interlock Door Systems

An interlock door system is one of the most secure methods of access control for controlled environments. In its simplest form, an interlock door system is composed of two doors electronically connected so that one cannot open until the other has closed. Its mechanism is similar to that of an airlock.

  • Automated doors are particularly suitable for areas with high volumes of traffic, as they reduce contamination by removing the need to touch the door surface.
  • Automated doors sustain less damage and wear from trolleys and other aggressive traffic, thereby increasing the life of the doors and reducing maintenance costs.
  • In controlled environments, particularly where rooms are operating under air pressure, using interlocks will provide a smooth effortless operation.
  • Interlocking doors provide one of the highest levels of entrance control and access management available which is critical for controlled environments.
  • It provides intrusion protection as it is resistant to ballistic and blast attacks.
  • Interlocking doors are often fitted with a range of different detection systems which enable them to detect and prevent multiple and unauthorised entries.
  • Interlocking doors are ideal for use in cleanrooms from pharmaceutical and food manufacturing to microelectronics and aviation industries.
