Cleanroom Swing Doors

Posted on by Dortek

Cleanrooms are tightly controlled environments used in various industries, such as pharmaceuticals, biotechnology and healthcare. The key objective of cleanrooms is to minimize particulate contamination and maintain specific levels of cleanliness. To achieve this goal, every component within a cleanroom must be carefully designed and specified, including the doors. Cleanroom swing doors play a vital role in maintaining the integrity of cleanroom environments by preventing the entry of contaminants while allowing access for personnel and equipment.

Specialized cleanroom doors are designed with meticulous attention to detail, considering factors such as air leakage prevention, durability, ease of cleaning, and compliance with stringent industry standards.

Key Features of Cleanroom Swing Doors

Cleanroom swing doors offer a range of key features and benefits that make them an ideal choice for controlled environments. Firstly, these doors are designed with airtight seals, ensuring minimal air leakage and maintaining the desired level of cleanliness within the cleanroom. This helps to prevent contamination and maintain sterile conditions. Furthermore, cleanroom swing doors are constructed using materials that are resistant to chemicals, making them highly durable and long-lasting.

Their smooth surfaces also make them easy to clean, reducing the risk of particle accumulation. Additionally, these doors can be equipped with interlocking systems to control access and enhance security. Another advantage of cleanroom swing doors is their ability to provide excellent sound insulation, minimizing noise pollution in sensitive work areas. Moreover, they are available in various sizes and configurations to suit different requirements.

Types of Cleanroom Swing Doors Available

Cleanroom swing doors are an essential component of controlled environments, ensuring the highest level of cleanliness and preventing contamination. Various types of cleanroom swing doors are available, each designed to meet specific requirements and standards. Firstly, flush cleanroom swing doors are widely used for their sleek appearance and seamless integration into the cleanroom walls. These doors have a completely flat surface without any protrusions or ledges, minimizing particle accumulation and facilitating easy cleaning.

Secondly, fire rated cleanroom doors provide an added layer of safety by offering fire resistance for a specified duration. These doors are constructed with special materials that can withstand extreme temperatures and prevent the spread of fire within the cleanroom. Moreover, double-leaf cleanroom swing doors allow wider access points while maintaining cleanliness standards. These doors consist of two independent leaves that can be opened simultaneously or individually, providing convenience in high-traffic areas.

Factors to Consider When Choosing Cleanroom Swing Doors

When selecting cleanroom swing doors, several crucial factors need to be taken into consideration. First and foremost is the door’s material. The chosen material should be compatible with the cleanroom environment, ensuring easy cleaning and preventing particle contamination. Secondly, the door’s design and construction must provide an airtight seal when closed, maintaining the desired pressure differentials inside the cleanroom. Additionally, considering the frequency of use is important as it affects durability and maintenance requirements.

Swing doors should be designed for smooth operation and withstand constant opening and closing without compromising cleanliness levels. Another factor to consider is the size of the door. It should be appropriately sized to accommodate equipment or personnel traffic while minimizing air exchange during entry or exit from the cleanroom. Furthermore, compatibility with access control systems may also be crucial, enabling secure entry while preventing unauthorized access.

Dortek’s range of door sizes and thicknesses are designed to integrate into all cleanroom modular panels. Our unique frame design offers a completely flush finish to any cleanroom wall panel of choice.

Considerable care and quality control goes into every Dortek door blade to ensure the smoothest possible finish. The fiberglass door blade is designed to have no sharp edges or 90-degree angles for ease of cleaning. Our frames are seamless, smooth, with round edges and seamless mitres with no crevices or dirt gathering areas.

We are constantly developing innovations to our product offerings to enhance the hygienic performance of our products. Small, but critical, features including flush fitting frames, recessed hinges, vision panels, lock keeps and receivers have all been continuously re-designed to minimise and eliminate dirt gathering areas in cleanrooms.

 

A Case Study From When We Supplied Cleanroom Swing Doors

We’ve collaborated with The Jefferson Institute for Bioprocessing in the United States on a couple of occasions. Initially, when they were inaugurated in 2019, we provided them with our cleanroom swing doors. In 2023, they had a similar requirement, and we were pleased to supply them with the same once again as well as a few other products like cleanroom windows and pass-through hatches.

In this blog post, we will discuss the vital role that X-ray doors play in healthcare facilities, the features that make them indispensable and why Dortek’s X-ray doors are the ideal choice for medical establishments.

The importance of X-ray doors in healthcare facilities

X-rays are a powerful tool for medical professionals, enabling them to diagnose and treat a wide range of conditions. However, as beneficial as they are, X-rays also emit ionising radiation that can pose a risk to human health if not adequately shielded. Consequently, it is essential to have proper protection in place for both patients and staff, that’s where X-ray doors come into play.

These specially designed doors offer a protective barrier against ionising radiation, ensuring that exposure levels remain within the acceptable limits outlined by the relevant regulatory authorities. By investing in high-quality X-ray doors, healthcare facilities can maintain a safe environment while providing top-notch diagnostic services.

Doors for ICUs

Posted on by Dortek

ICU door in a hospital environment.

What is an ICU?

Intensive care units (ICUs) provide around-the-clock care for people who are critically ill. Patients in ICU units are severely ill and require much more hands on care than in normal wards which makes them more susceptible to HAI’s. This is why the design of ICU facilities has become an essential part of preventing HAI’s and improving both patient safety and infection control.

ICU doors need to meet strict requirements in ICUs as they’re in such a critical environment. ICU doors can be a major source of contamination due to the fact they are the piece of furniture which is touched the most by patients and staff. This is why it’s critical that the correct doors are specified for ICU facilities.

 

We’re experts at providing specialist doors for ICUs

In hospital environments, safe and efficient patient care requires the versatility, durability and safety features of Dortek ICU doors.

Dortek doors have a hygienic flush surface which is easy to keep clean. Our large glass door blades are strong and durable and help to maximise vision and light, even when the doors are shut. Our glass doors can also be provided with x-ray rated glass, blinds or smart glass for patient privacy.

Doors can be automated to provide hands-free entry and further reduce the risk of infection. Dortek uses an intelligent automation which is key for user safety. Our door automations react to the smallest obstruction and photo sensors stop the door from closing onto passing traffic. We also provide a range of access control systems, locking and interface with BMS (Building Management Systems) for extra security.

Our doors are designed for intensive care units, but they’re also ideal for laboratories, surgical suites, waiting areas and diagnostic imaging areas. We have an extensive range of case studies from across the globe where we have fitted & supplied our specialist healthcare doors. You can find them here.

 

Hermetically Sealing ICU Doors

Dortek’s hermetically sealing sliding glass doors are designed specifically to help cut the spread of airborne infection.

The door has a unique patented track system so it seals perfectly against the floor and frame.  The efficiency of the seal has been officially tested and results show it to be over 99% effective thus helping to reduce air handling costs, the incidence of wound infections and cross contamination.

Guiding and sealing cams are fitted outside the clear opening eliminating the requirements for a floor track, allowing free unrestricted access for wheeled traffic. This is enables trouble free access for beds and other medical equipment required in intensive care units.
