Key Features Specifiers Look For

A cleanroom door is part of the controlled envelope: it must close reliably, seal consistently, and stay hygienic after thousands of cleaning cycles.

Flush, Hygienic Surfaces That Stay Clean and Repairable

Cleanability starts with geometry. Euwoo designs door leaves and frames with flush faces, minimal seams, and smooth transitions at vision panels and hardware cutouts. This reduces dust traps and makes wipe-down faster, especially in corridors that must be sanitized multiple times per shift. Surfaces can be supplied in brushed stainless steel or durable powder-coated steel, with edge protection options to reduce damage from carts. Optional antimicrobial coating systems and HPL skins can be considered where chemical compatibility and long-term color stability are critical.

Repeatable Sealing Performance for Controlled Pressure Regimes

Airtight performance is mainly about repeatability. We build sealing systems around continuous perimeter gaskets, consistent latch compression, and threshold strategies that match your airflow design. In positive-pressure cleanrooms, a stable seal reduces uncontrolled leakage paths and helps maintain room-to-corridor differentials. For airlocks, predictable closing and sealing supports interlock logic and minimizes contamination transfer during door cycling. We offer EPDM or silicone gasket materials, optional drop seals for the bottom edge, and frame profiles that support clean, continuous gasket contact.

Flush Vision Panels Designed for Hygiene and Safety

Vision panels improve safety and flow, but they can become contamination points if the glazing is proud, cracked, or difficult to clean. Euwoo uses flush glazing approaches where the glass and surrounding bead are designed to minimize ledges on both sides of the door. This supports hygienic cleaning, reduces particle accumulation, and improves durability under repeated disinfectant exposure. Choose clear, frosted, or tinted glass depending on privacy needs, and size the panel based on sightline requirements and door strength.

Interlocks, Access Control, and Automation That Remain Serviceable

Many controlled environments rely on airlocks, segregation, or directional flow. Our cleanroom doors can be prepared for electric strikes, maglocks, card readers, and door position sensors, enabling integration with access control systems and BMS. For airlocks, we support mechanical and electronic interlock solutions, including signal-ready wiring routes, indicator light provisions, and fail-safe planning for emergency egress. Automation options such as swing operators or automatic sliding drives can reduce touchpoints and improve compliance with process flow.

Material and Finish Choices Matched to Your Cleaning Chemistry

Material choice should follow cleaning method and corrosion risk. Stainless steel (commonly 304, with 316 available for higher chloride environments) performs well where wet washdown, aggressive disinfectants, or humidity are routine. Powder-coated galvanized steel can be cost-effective for many ISO 7-8 corridors and support areas, provided coating chemistry is selected for the cleaning agent set. Share your cleaning chemicals, frequency, and temperature exposure, and we will recommend the material and finish approach that protects lifecycle cost.

Submittal-Ready Engineering Support

Projects are approved on documentation, not marketing claims. Euwoo supports contractors and specifiers with a submittal-oriented process: drawings that reflect wall thickness and handing, a clear hardware set list, and options mapping that avoids scope gaps. We can provide material certificates for stainless grades, finish references such as RAL color, and QC checkpoints aligned to your inspection plan. Packaging and labeling can be customized for phased deliveries, reducing site confusion and speeding installation.

Hygienic cleanroom door surface detail

Sealing and Hygiene Design

In controlled environments, the details at the perimeter decide performance. Euwoo focuses on sealing repeatability and serviceability so the opening can be maintained over years of operation.

Perimeter Gasket Strategy

Continuous gaskets are only effective when compression is consistent. We coordinate gasket selection with frame profile, hinge positioning, and latching points so gasket contact is even around the opening. EPDM and silicone are common choices, selected based on cleaning chemicals and temperature exposure.

Bottom Sealing and Thresholds

The bottom edge is often the weakest point in a cleanroom door system. Threshold choices are driven by cleaning method, cart traffic, and accessibility needs. Options can include low-profile thresholds, sweep and drop-seal approaches, and detailing that supports sanitation without creating trip hazards.

Frame-to-Wall Interface

Even high-quality door leaves cannot compensate for poor frame-to-wall sealing. We provide detailing guidance to help installers achieve continuous seals at the frame perimeter, including coordination for wall thickness, panel systems, and sealant compatibility.

Flush Glazing and Hardware Transitions

Vision panels and hardware cutouts create geometry changes that can trap particles if not handled correctly. Flush glazing options minimize ledges, while hardware selections are coordinated to avoid unnecessary protrusions.

Commissioning and Maintenance Readiness

Seal performance depends on installation quality and ongoing adjustment. We recommend commissioning checks that confirm door closing, latch engagement, seal contact, and interlock function. We design for replacement of gaskets and wearable parts without complex disassembly.

Pre-Install Coordination

Confirm wall thickness, clear opening size, handing, and swing clearance. Verify hardware schedule and any interlock or automation requirements before frames are fixed.

2

Frame Setting and Anchoring

Set frames plumb and square, maintaining consistent reveals. Use anchoring methods appropriate to wall type and ensure interface remains accessible for sealing.

3

Frame-to-Wall Sealing

Apply sealing methods compatible with wall system and hygiene requirements. The goal is a continuous, cleanable interface without gaps that trap residue.

4

Leaf Hanging and Hardware

Install hinges, closers, and latching hardware to achieve reliable closing and consistent compression at the gasket line. Adjust closing speed and latch action as needed.

5

Bottom Detail and Threshold

Install threshold or bottom sealing strategy aligned to flooring build-up and cleaning practices. Confirm cart traffic needs and accessibility requirements.

6

Cleanroom Door FAQ

Common questions from contractors and project teams about sourcing cleanroom openings.

What makes a door suitable for a cleanroom?
A cleanroom door is evaluated on hygiene, sealing consistency, and serviceability. Hygiene comes from smooth, cleanable surfaces with minimal seams. Sealing consistency depends on gasket selection, reliable latching compression, and a bottom-edge strategy that matches flooring and cleaning practices. Serviceability matters because gaskets, closers, and locks wear over time and must be replaceable without damaging the door.
How do I specify an ISO cleanroom door?
Start with the room classification and pressure regime requirements. Then define hygiene detailing (flush surfaces), sealing strategy (perimeter gasket and bottom detail), and operational needs (vision panels, access control, interlocks, automation). Include wall thickness and construction type so frames can be designed correctly, and require submittal drawings that show all cutouts and interfaces.
Can your doors be used in GMP facilities?
Yes, Euwoo supplies door packages commonly specified for GMP-regulated facilities. Selection focuses on smooth surfaces tolerant of frequent disinfectant wipe-down, sealing coordination for pressure control, and operational features such as airlock interlocks. We support the process with configuration discipline and documentation.
Should I choose swing or sliding doors for airlocks?
Both can work. Swing doors are common and have straightforward maintenance but require swing clearance. Sliding doors reduce collision risk in tight corridors and support automation well but require planning for operator service access. For airlocks, the interlock system is often more critical than the leaf type.
Do you support interlock systems for airlock doors?
Yes. Airlock doors can be prepared for mechanical or electronic interlock solutions. Electronic interlocks typically use door position sensing and controlled locks to prevent simultaneous opening. We help coordinate wiring routes, hardware cutouts, and service access so the interlock remains maintainable after handover.
What material is best: stainless steel or powder-coated steel?
Stainless steel is preferred where wet cleaning, high humidity, or aggressive disinfectants are routine. Powder-coated galvanized steel can be cost-effective for many controlled corridors, but coating chemistry should be aligned to cleaning agents. In both cases, edge detailing and hardware compatibility matter to avoid corrosion initiation points.
How do you handle different wall thicknesses and panel systems?
We request wall thickness and construction details early so the frame profile, anchoring method, and frame-to-wall sealing approach can be coordinated. For modular panel systems, the interface must remain cleanable and continuous. We provide drawings that show how the frame sits in the wall system.
How are flush vision panels designed to stay hygienic?
Flush glazing reduces ledges where residue can accumulate. Hygienic performance depends on glazing bead design, edge protection, and how the panel is integrated so it remains stable under cycling and cleaning. We focus on minimizing seams and coordinating panel size to maintain door strength.
What do you need to quote a cleanroom door project?
We typically need a door schedule (sizes, quantities, handing), wall thickness and construction type, and required options such as vision panels, access control, interlocks, and automation. Finish requirements and chemical exposure information help avoid re-specification later. If the project includes airlocks, define the interlock logic.
What is the typical lead time and how do you support export delivery?
Lead time is typically 25-45 days after drawings and option mapping are confirmed. We support export delivery with packaging that protects finishes and edges, clear labeling aligned to door schedules, and documentation such as packing lists. For phased projects, labeling and batching reduce site confusion.
