Pharmaceutical and medical grade cleanroom several features that make them unique from prototypical cleanroom doors. Particularly, Terra Universal is one of the few cleanroom construction companies that self-manufacture doors specifically for installation in controlled environments, cleanrooms, and bio-pharmaceutical labs. Terra can provide a wide range of outfitting and engineering services to support virtually any facility or compliance requirement. When comparing hygienic versus sterile cleanroom door styles, each model and product family is designed to meet a specific fit and function.
In critical production facilities, entry and exit doors ensure a physical barrier between a controlled indoor environment and the outside world. In the most hygienic of operations, special considerations are required when selecting an appropriate door to maintain a specific air quality classification and to support frequent chemical treatments needed during cleaning, sanitation, and disinfection regimens.
Are all medical-grade doors hermetically sealed? The simple answer: no. Hermetically sealed doors imply that the door creates a sealed air barrier between two environments on a shared wall. In contrast, hygienic doors are designed to reduce air transfer and air leakage from a cleanroom, but are not designed to entirely prevent air from flowing under and around the door gaps.
Simply, a hermetic door typically includes all of the same cleanliness characteristics as a hygienic door, but only hermetic doors are designed for precise control and containment of airflow between partitioned rooms in containment or isolation scenarios.
Terra Hygienic Doors imply that the entire door entry system is designed with smooth, impervious, and minimal cracks and crevices for easy cleaning. Hermetic doors share these same features, but have additional air lock features to ensure that the door system creates and maintains air pressure once engaged. Terra offers numerous styles of doors to meet virtually any environmental requirement. For those in need of air sealed doors, Terra Universal is an authorized Dortek hermetic door dealer.
Hermetic Sealing Hinged Doors by Dortek prevent air leakage in cleanrooms, BSL3 / BSL4 labs, and pharmaceutical manufacturing. A unique wrap-around frame incorporates a neoprene seal that resists chemical treatment, warp, rot, swell or rust. GRP doors are made of glass reinforced plastic, which is a strong and durable material that is resistant to weather and UV rays, which makes it a robust and reliable choice that is easy to clean and will not harbor bacteria.
Hermetic Sealing Sliding Doors are perfect for environments where hygiene and air leakage control are critical. Dortek's hermetic cleanroom doors have a patented track system that creates a perfect seal between the floor and frame (independently tested to be over 99% effective). Door construction encompasses a 60mm thick panel with a hard plastic laminate finish, and a smooth sliding action that reduces air disturbance and mitigates airborne contaminant dispersion. Terra is an authorized Dortek distributor and offers several models in single or bi-parting styles with configurable manual hardware controls and hermetic openers.

Terra's automatic cleanroom doors facilitate maintained differential pressure inside a cleanroom. A fully concealed drop-down gasket seals the bottom gap, to minimize air leakage and maintain room pressure values. Programming the door after installation is designed for simplicity, and does not require special equipment nor a certified field technician. Stainless steel construction supports a broad spectrum of chemical compatibility and will not shed particulates. Flush mount window panes simplify cleaning and eliminate cracks and crevices between the door frame and viewing the panel to simplify cleaning. Finally, electromagnetic door interlocks ensure that only one door in a room or partition can be at a time. Interlocks prevent nearby doors from opening simultaneously, which would otherwise result in a turbulent transfer of air between dirty and clean air from juxtaposed spaces. enter the room at the same time from different doors. The product is also Leak Rated by UL to maintain cleanroom pressure gradients.
Terra's recessed automatic doors feature a touchless motion opening that arrives pre-assembled as a complete unit for easy installation. The 304 stainless steel, ANSI compliant doors are well suited for room partitions or to support a larger door when passing through high-volume foot or wheel traffic.

Flush mount dual-pane window design simplifies cleaning. Terra's BioSafe Door viewing windows are constructed of two 1/4” tempered glass panes that are factory-mounted, bonded, and encased in a durable stainless steel frame.
Electromagnetic door interlock systems reduce cross-contamination by ensuring specific doors never open simultaneously. The central control module connects to electronic maglocks, allowing up to 6 interlocking doorways. Maglocks engage with 600lb of holding force and can be easily disabled in case of an emergency.
Terra cleanroom door assemblies are leak-rated by UL for a tight seal to maintain cleanroom pressure gradients. Unless specifically noted, doors are not hermetically sealed and not intended for spaces mitigating operator exposure to biohazards, chemicals, or nauseating odors
Manual Swing Doors are typically placed between partitions that separate two adjacent spaces of different air pressure, or when a single door separates a clean area or corridor from dirtier adjacent spaces.
The aluminum and stainless steel pre-hung doors use the same knock-down steel U-frame design. Frames are customizable to various wall thicknesses, and the U-Frame will arrive assembled and fit on stud frame walls. Note, installation does require two or more people to safely and effectively install the door. Before starting installation, make sure the frame opening is the correct width and is perfectly vertical, square and level. If the opening is not correct, it can cause issues with the door fit as well as hardware function.
Terra's aluminum pre-hung automatic doors are pre-assembled to a frame for quick and easy installation, and come with either stainless steel push or pull handles and heavy-duty stainless steel flush-mounted mortise hinges for added durability. To ensure stability and security, all hardware locations are reinforced with internal steel backing plates.
