Dortek to supply FRP doors to the only training institute for biopharmaceutical processing in North America.

Dortek have been specified to supply and install our hygienic FRP doors to The Jefferson Institute for Bioprocessing (JIB) facility as part of a refurbishment.

The Jefferson Institute for Bioprocessing is a full-service development and training organization specializing in biopharmaceuticals and biologics. They offer early phase pre-clinical process development, product development, analytical, quality control, stability and release testing, world-class industry training, and strong credential programs through Thomas Jefferson University.

Located in Spring House Innovation Park in Lower Gwynedd, Pennsylvania, the JIB gives scientists, engineers and technicians access to a state-of-the-art bioprocessing training facility where they can practice complex bioprocessing procedures using industry-grade equipment. The Institute has received a $2 million grant to add nearly 40,000 square feet of additional academic and training space.

JIB partners with the National Institute for Bioprocessing Research and Training (NIBRT) in Dublin, Ireland. JIB training courses use the internationally recognised NIBRT curriculum and are certified by NIBRT.

Dortek supplied our specialist FRP door systems to the facility when it first opened in 2019. The institute is designed to simulate a GMP manufacturing plant where biologics are made so it was crucial the doors met GMP standards. Dortek supplied FRP doors in Stainless Steel frames, cleanroom windows and pass-through hatches. Dortek fiberglass doors have an inorganic, wood free construction which makes them ideal for biopharmaceutical facilities.

Novosprint Mono High-Speed Door

The Butzbach NOVOSPRINT Mono is a high-speed door with a sideways opening door leaf, specially designed for fast, unobstructed, and contactless traffic.

As it is a high-speed door with a single lateral opening, it offers many advantages compared to swing, stackable or sliding doors. It is the ideal solution for narrow passages or corridors, where there is limited space.

With a rebate profile depth of just 35 mm on the wall side, this installation variant makes almost the entire opening width available for use.

The side opening ensures no dirt gets from the ground onto workers or the goods being transported. Unlike vertically opening doors, dust or liquids can’t be pulled upwards with the closing edge before then falling or dripping down.

The NOVOSPRINT high speed door range is an investment that pays off, more efficiency, greater reliability and a long service life.

The Essential Role of X-ray Doors in Modern Healthcare Facilities

The world of healthcare has undergone rapid transformation in recent years, with technology and innovation at the forefront of these changes. One of the critical aspects of modern healthcare facilities is their ability to provide accurate and reliable diagnostic services. X-ray technology is an indispensable tool for this purpose and ensuring safety in these areas is of paramount importance. That’s where Dortek steps in with its cutting-edge X-ray doors.

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.

  1. Lead-lined protection: Dortek’s X-ray doors are equipped with lead lining, which effectively shields against radiation leakage, ensuring the safety of patients and healthcare professionals.
  2. Seamless, hygienic design: Our doors are designed with seamless edges and a smooth surface, minimising the risk of bacteria and infection spread. They are also easy to clean and maintain, making them perfect for the stringent hygienic requirements of healthcare settings.

Doors for ICUs

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.

Doors for Life Science Facilities

In life science facilities, doors play an important role in ensuring the safety and security of the people working within the facility and the research itself.

Choosing the correct door system is a critical part of the design within these facilities, as compliance with standards, ease of traffic movement, hygiene, fire regulations and balance of air movement will dictate the types of door being used or specified. In addition, doors must be seamless, waterproof, resistant to cleaning regimes and free of voids and organic material such as timber where bacteria could multiply.

The following are some of the key reasons to use specialist door types like hygienic GRP/FRP in research and life science facilities;

  • Doors should have a smooth, seamless hygienic construction, and must be designed to be easy to clean and keep clean.
  • The door and frame should be completely void free – there should be nowhere that moisture and bacteria can gather undetected.
  • Doors should be resistant to the commonly used cleaning and fumigation agents used in research facilities.
  • Doors should remain dimensionally-stable. Unlike timber-cored products, a GRP/FRP door leaf will not bow, warp, crack or deflect whatever the temperature or humidity.
  • Ledges should be minimised (windows should be frameless and completely flush to both sides of the door).
  • Doors should be lightweight, yet very strong. They should be easy to operate by facility users. They should have solid, yet durable finishes to prevent the formation of chips where micro-organisms can find egress.
  • Fire doors should be third party fire certificated to the appropriate UL, BS, EN, China, Singapore, Australia, and NZ standards.
  • Doors have the ability to be equipped with a range of access control systems and interlocking to prevent unauthorized entry.
  • Doors should have a self-closing system and, where required, air locking mechanisms to provide a tight seal and prevent the spread of hazardous fumes or materials.
  • Doors should be available with lead lining for radiation control.

By choosing the right doors for their life science facilities, facility and building owners can ensure the safety, security, and integrity of their research. Dortek have supplied our specialist doors to 14 of the top named research universities in the world.

Dortek’s Waterproof Doors

Dortek is a leading provider of hygienic doors, including waterproof doors. In this blog, we will explore why Dortek waterproof doors are specified by our clients and their benefits.

The benefits of Dortek waterproof doors

For wet or moisture-prone areas the design of a building becomes increasingly complex, with buildings needing to withstand both warm, humid conditions internally but also cold external conditions throughout the winter. Doors in these areas will need to be versatile in order to withstand severe temperature variations, damp conditions and the frequent use of chlorine/cleaning chemicals.

Choosing the correct waterproof doors is essential to maintaining good hygienic and longevity. In industries such as leisure, healthcare, food and pharmaceuticals, maintaining hygiene and cleanliness is of utmost importance. Waterproof doors are designed to resist moisture and prevent bacterial growth, making them an ideal solution for environments that require high levels of cleanliness.

Waterproof doors are designed to withstand exposure to water and moisture, making them more durable than traditional doors. They are less likely to warp, rot, or decay and they can withstand a wide range of temperatures, from extreme heat to extreme cold.


Dortek’s Waterproof Doors - GRP vs Timber.

The results of specifying the wrong door

Timber doors have an organic core with natural seams and crevices which makes them impossible to keep clean. These doors also soak up any moisture which will cause them to swell, warp, rot and decay. The door also knocks, chips and splinters easily, which in turn creates perfect breeding grounds for bacteria to grow.
