Hermetic Sliding Door — RAX Door Technology
01 · Overview

Airtight Sealing for Controlled Environments

Hermetic sliding doors are engineered for environments where airtight sealing is critical — clean rooms, pharmaceutical facilities, food processing plants, and controlled atmosphere storage. Unlike standard industrial doors that allow air exchange, hermetic doors feature multi-layer sealing systems that prevent air, dust, and contaminant transfer between zones.

RAX manufactures hermetic sliding doors with smooth stainless steel or aluminum panels, multi-layer EPDM sealing systems, and servo motor drive. Opening speeds up to 1 m/s minimize exposure time during each opening cycle. Airtight sealing maintains positive pressure differentials and clean room classification.

These doors are essential for pharmaceutical clean rooms, food processing facilities with strict hygiene requirements, controlled atmosphere storage, and any environment where air exchange must be minimized.

02 · Key Features

Engineered for Airtight Sealing

Multi-Layer Sealing System

Multiple EPDM seals on all four sides create airtight barrier. Perimeter seals, inter-panel seals, and bottom seals work together to prevent air exchange. Maintains positive pressure differentials between zones.

Smooth, Cleanable Surfaces

Stainless steel or aluminum panels with no crevices or seams where contaminants can accumulate. Easy to clean and sanitize. Suitable for clean room and food-grade environments.

High-Speed Operation

Opening speeds up to 1 m/s with servo motor drive. Frequency converter for smooth acceleration/deceleration. Minimizes exposure time during each opening cycle.

Positive Pressure Maintenance

Fast operation + airtight sealing maintains positive pressure in clean rooms. Critical for preventing contamination ingress. Supports ISO 14644 clean room classification.

Hygienic Design

Smooth surfaces resist bacterial growth. No sharp corners or crevices. Suitable for washdown environments. Compliant with HACCP and GMP requirements.

Smart Control

PLC-based control with LCD display. Integration with clean room monitoring systems. Remote operation and diagnostics. Programmable speeds and delay times.

Where Hermetic Doors Excel

Pharmaceutical Clean Rooms

GMP-compliant environments require strict contamination control. Airtight sealing maintains positive pressure. Smooth surfaces easy to clean and sanitize. Fast operation minimizes exposure time.

Food Processing Facilities

HACCP-compliant hygienic design. Airtight sealing prevents cross-contamination between zones. Smooth surfaces resist bacterial growth. Fast operation maintains temperature zones.

Controlled Atmosphere Storage

Modified atmosphere packaging and storage require airtight environments. Hermetic doors maintain gas composition. Fast operation minimizes atmosphere loss during access.

Biotechnology Laboratories

BSL-2 and BSL-3 laboratories require strict containment. Airtight sealing prevents pathogen escape. Smooth surfaces easy to decontaminate. Fast operation supports workflow efficiency.

Semiconductor Manufacturing

Clean room environments for chip manufacturing. Airtight sealing prevents particle ingress. Smooth surfaces minimize particle generation. Fast operation supports production throughput.

Hospital Isolation Rooms

Negative pressure isolation rooms require airtight sealing. Hermetic doors prevent pathogen spread. Smooth surfaces easy to disinfect. Fast operation supports emergency access.

06 · Compliance

Applicable Standards

EN 13241:2003+A2:2016

Core CE product standard for industrial, commercial, and garage doors. Covers both manual and powered doors. Requires Declaration of Performance (DoP) under CPR 305/2011.

EN 12453:2001

Safety requirements for powered doors. Specifies force limiting, safety devices, and control system requirements.

ISO 14644

Clean room classification standard. Hermetic doors support clean room classification by maintaining positive pressure and preventing contamination ingress.

CE Marking

Mandatory for export to EU/UK markets. RAX provides CE technical file and Declaration of Performance with every shipment.

What makes a door “hermetic”?

Multi-layer EPDM sealing system on all four sides creates airtight barrier. Perimeter seals, inter-panel seals, and bottom seals work together to prevent air exchange. Maintains positive pressure differentials between zones.

Are hermetic doors suitable for clean rooms?

Yes. Smooth stainless steel or aluminum panels with no crevices. Multi-layer sealing maintains positive pressure. Fast operation minimizes exposure time. Supports ISO 14644 clean room classification.

What is the opening speed?

Up to 1 m/s opening speed, 0.8 m/s closing speed. Speed is adjustable via PLC control system. Servo motor with frequency converter ensures smooth operation.

Can hermetic doors withstand washdown?

Yes. IP65 sealed motor housing protects against water ingress. Stainless steel hardware resists corrosion from cleaning chemicals. Smooth surfaces easy to clean and sanitize.

Do you provide installation?

No — RAX is a pure manufacturer. Doors ship with English installation manuals, wiring diagrams, and remote support.

What is the lead time and warranty?

Standard configurations: 12–20 days. Custom first order: 20–35 days. Repeat orders: 15–20 days. Warranty: panels 10 years, motor and control 5 years.
