The Cold Storage High Speed Door is built for chilled environments where every open cycle risks warm-air ingress, condensation and ice build-up. Fast cycling plus tight sealing limits air exchange, while heated frame/track and bottom-edge options keep guides and seals ice-free in sub-zero conditions.
Cold-storage rapid doors are rated by operating temperature. For reference, Seppes lists its zipper-track and brush-track cold-storage doors for use above 0 C and its fold-up freezer door for 0 C to -25 C. RAX products are tested from -30 C cold storage to +50 C desert; RAX confirms the temperature rating, heating package and sealing for your room per project.
As a pure manufacturer, RAX builds each cold-storage high speed door to your exact opening and RAL color – from prototype to container-load delivery order – with wiring diagrams and English manuals for your local installers.
Sources & honesty: RAX-company facts on this page (materials, 100,000-cycle fatigue testing, certifications held, warranty, lead time) are from RAX Door Technology’s approved brand brief. Industry benchmark figures (typical opening speeds, cycle-life ranges, EN 12424 wind classes, ISO 14644-1 cleanroom classes, competitor reference points) are drawn from our sourced category research (research/high-speed-doors.md) and are marked as industry-typical or attributed to the named manufacturer. RAX’s own measured speed, U-value, wind-class certificate and cleanroom class are confirmed per project by test – we do not publish them as generic figures. Fire resistance (EN 1634-1) and ATEX suitability are project-specific capabilities, not blanket certificates.
Curtain and seals rated for chilled duty; RAX products tested from -30 C cold storage to +50 C desert.
Heated frame/track and heated bottom edge options prevent ice build-up and keep seals flexible below 0 C (industry-standard practice for sub-zero doors).
Rapid operation plus peripheral sealing limits warm-air ingress and condensation at the opening.
Closed-loop servo or VFD – both manufactured in-house by RAX; servo motor backed by a 5-year warranty.

| Order | Custom engineered to your exact opening, specification and RAL color |
Provide clear opening width x height, headroom and side room – or site photos. We produce the confirmation drawing and confirm the feasible span against wind class.
Cycles per day, operating temperature range, wind exposure, and clean / cold / washdown / hazardous-area duty.
Target speed, thermal (U-value), wind (EN 12424), fire (EN 1634-1), acoustic or cleanroom class – we match the applicable standard and confirm by test.
Servo or VFD drive, sensing (radar / geomagnetic / light-curtain), safety edges and any safety-interlock or smart (WiFi/RS485) control needs.
Fast, tight doors for 0 C to moderate sub-zero chilled zones.
Hygienic, draught-limiting doors in cold production environments.
Buffer and corridor doors in distribution cold stores.
Temperature-stable openings with tight sealing for sensitive stock.
RAX supports full private-label production of the Cold Storage High Speed Door: custom RAL panel colors, operator matching, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds, Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.
Product standard for industrial, commercial and garage doors – the harmonized basis for CE marking. Covers mechanical and power-operated safety, wind-pressure and water-penetration resistance, thermal (U-value) and air-permeability performance, with technical documentation retained 10 years.
Safety in use of power-operated doors – operating-force limits and entrapment protection, and the test methods behind our operator safety data.
Wind-load resistance classification (Class 0-5) and the test method for doors. Class 0 denotes no declared wind performance; Class 5 (‘Exceptional’, above 1000 Pa) is set by special maker-buyer agreement.
Any opening size within the High Speed Doors range – large industrial doors from prototype to container-load, full flexibility on order quantity. Share your opening width x height (or site photos) and our engineers confirm the feasible span, wind class and drive sizing, then produce technical drawings.
Cold-storage rapid doors prioritize fast, tight cycling to limit warm-air ingress rather than maximum speed; market rapid doors broadly span ~0.6-2.0 m/s by type (industry synthesis). RAX confirms the travel speed and sealing for your room in the quotation.
Below 0 C, moisture freezes on guides and seals, so RAX offers heated frame/track and a heated bottom edge to keep the door running and the seals flexible – this is industry-standard practice for sub-zero rapid doors. RAX products are tested from -30 C cold storage to +50 C desert, and we confirm the temperature rating and heating package for your specific room.
We are a pure manufacturer and do not provide on-site installation. Every order ships with an English installation manual, wiring diagrams for your local installation team; operators are pre-set and tested before dispatch.
RAX holds ISO 9001:2015 and CE to EN 13241 (industrial door) and EN 12453 (operator safety), with SGS material reports and product liability insurance. Fire resistance (EI60/EI120) and an EN 12424 wind-load class are project-specific capabilities we test and certify per order against the matching standard – we do not overclaim a blanket rating.
Yes. RAL panel colors, operator matching, packaging printing and manual translation (EN/ES/FR/AR/RU) are all supported, from an OEM sample to container-load branded production, under strict NDA.
