A high-speed door is bought for one reason — to be open for the shortest possible time while a forklift passes, and closed the rest of the day. In cold storage that means less ice on the floor and lower compressor load; in pharma it means pressure and particle control. Here is what to put in the specification.
Activation. Radar for people and vehicles approaching, induction loops for forklifts, and pull-cords or push-buttons as back-up. For cold rooms we prefer loops or long-range radar so the door opens before the forklift reaches it and closes behind it.
Curtain. PVC curtain with a vision panel so drivers see across. Ask for a self-repairing curtain — if a forklift clips it, the curtain pops out of the guides and re-feeds itself on the next cycle instead of tearing. For freezer rooms the door needs an insulated or double curtain and heated side guides so it does not freeze shut.
Motor and speed. SIE servo and gear motors (SIE40 to SIE100 class) give opening speeds that match the traffic without hammering the door. Specify the number of cycles per day — a dispatch door doing 1,000 cycles needs a different drive from a lab door doing 50.
Safety. Photocells and a light curtain across the opening, a soft bottom edge, and a brake that holds the curtain if power fails.
Hygiene and compliance. Stainless or powder-coated frames that tolerate wash-down, flush surfaces without dust ledges, and for pharma an interlock so two doors in an airlock cannot open together. We supply the material certificates and interlock logic your audit file needs.
Installation is usually one day per door once the opening is ready. Send us the opening size, the temperature on each side and the number of cycles per day for a specification and budget.
