FAQ

What is the difference between a PVC roll-up, zipper, spiral and freezer high speed door?

PVC roll-up doors use a flexible curtain and suit frequent internal traffic at the lowest cost. Zipper doors have a curtain that re-enters the guides after an impact. Spiral doors use aluminum slats that coil without contact, for exterior and security openings. Freezer doors use a ~30 mm insulated curtain and heated side rails for cold rooms.

Which type should I use for a cold room or freezer?

The LESHO freezer high speed door: working temperature −35°C to 65°C, sizes up to 6000×6000 mm, ~30 mm insulated curtain, heated side rails, IP55, about 1.8 m/s open and 1.6 m/s close.

How many cycles per day should a high speed door be sized for?

Size the door by your peak cycles per hour and expected cycles per day, and include these figures in your quote request so the motor and controls can be matched to your traffic.

How is a high speed door priced?

Price depends on opening width × height, door type, curtain or slat material, motor and controls, safety devices and quantity. Send these details to LESHO for a free quote.

What do I need to send for a quotation?

Opening width and height, indoor or outdoor use, temperature, traffic per hour, power supply (voltage/phase), activation method and quantity.

What warranty and lead time apply?

LESHO offers a 1-year warranty and a normal lead time of 15–20 days. Certification details are available on request.
