Modular white room vs. Conventional construction: when to choose each
The white room or clean room concept, as it used to be called when they appeared at the end of the 19th century, we associate it with operating rooms, pharmaceutical industry, nuclear, etc. But the truth is that every day it is more implemented in different sectors such as food or cosmetics. White rooms should ensure that no contaminating particle enters the room, so the door interlocking system is essential. At Labsom we tell you all about how to properly close doors for clean rooms.
The White rooms They are controlled spaces and designed to maintain minimal levels of contamination inside. They are isolated spaces that are actively cleaned, avoiding contamination of particles and biological materials or vaporized particles such as dust and that are transported by air. The doors of a clean room are therefore fundamental, since they guarantee, that the number of these particles that can access the interior is as little as possible. Therefore, the care of the environment, the materials and the accesses to these spaces must be rigorously controlled.
At Labsom we work with compliance with the ISO regulations and GMP (Good Manufacturing Practices), named in the international arena. They are good manufacturing standards that must be complied with by the manufacturers of products, medicines and many other sectors, with the main objective of obtaining the proper guarantees of quality and quality. This, of course, also applies to doors for clean rooms and, specifically, the different systems that exist for the interlocking of the doors.
The white room door interlocking system is one of the primary systems that we offer at Labsom and that are fully integrated into our cleanroom doors and Pass-Box or Pass-Trolley equipment. This system is made up of two doors, both with a red/green traffic light, an emergency release button, an electric lock and a control unit.
The purpose of the door locking system is to avoid communication between two different spaces at the same time. That is, the two doors cannot be open at the same time, since the entry of polluting particles could occur. When the two remain closed, all traffic lights will be shown in green and one of them can be opened. At the moment when a door opens, the opposite traffic light will change to red, blocking this door through the electric lock and equalizing the pressures of both rooms. That is why the two doors of the clean room may not be open at the same time, being necessary to close one door to enable the other to open.
the emergency mushroom
In an emergency, what we call emergency mushroom comes into play. The emergency mushroom is the button located next to the traffic light, it allows you to force the system and open the door, even when the traffic light remains red. The emergency mushroom, although in principle should not be necessary, is essential because it should be used in the event of an emergency and it is necessary to force the system.
As we have pointed out before, each door has a traffic light and an aperture sensor connected to each other. These are installed perfectly flat on the door jambs of the clean room and there are different types for each type of door to complement the door locking system.
easy prox: Proximity sensor, allows the opening of the door locking system with the approach of a hand to the touch sensor.
Easy Lights: traffic light with button. This type of access is made up of a red/green LED light and with a central emergency release button.
easy code: Access with alphanumeric code, for access entries using an alphanumeric code programmed on the keyboard.
Easy Badge: Autonomous proximity plate reader, for authorized entries through the exclusive use of personal cards. In addition, it has a platform and software for remote access control in real time.

In addition to door interlocking, we know that there are other systems that are equally important to guarantee the specific conditions that must occur within a room of this type. For example, the ventilation system in clean rooms is vital to maintaining minimum levels of contamination, but there are more factors that we must take into account.
Now that you know the importance of these spaces, Labsom is placed at your entire disposal for any questions that may arise about what the interlocking systems are and what they are used for in the clean rooms. Don’t hesitate to Contact usyes!
If we want to guarantee that the environment within a clean room meets the conditions of asepsis and level of polluting particles established by the regulations, it is essential that the doors of the room are prepared with a door interlocking system that guarantees safety.
Cleanroom materials must meet certain requirements to maintain a level of cleanliness and safety throughout the product handling and transfer process. The most important thing in a clean room is hygiene, so without a doubt the most important thing when we talk about the material of the doors is that it is easy to clean and that it will allow to be cleaned in depth.
There is no type of traffic light that is better than another. The main difference between them is the process to allow the door to open, but they all work correctly in ensuring that the doors are correctly closed and that the level of particles from the entering from the outside is the least possible.
We handle the design, installation, management, and maintenance of cleanrooms, prioritizing safety and offering customized solutions. We will also contact you to discuss your project and prepare a quote tailored to your needs.
