coolroom doors FAQ
1. How does the zipper design improve the insulation of this cold storage doors manufacturer model?
The zipper lock creates a virtually airtight seal between the curtain and track, eliminating air convection, which is the most significant source of heat gain and energy loss in coolroom doors.
2. What is the benefit of the dual-shaft technology over traditional doors?
Traditional high-speed doors rely on bulky counterweights. Our patented dual-shaft drive eliminates the need for weights, reducing mechanical complexity, lowering maintenance, and allowing for much faster, smooth cycling.
3. Does the curtain self-repair if hit by a forklift?
Yes, the insulated zipper curtain is designed to release upon impact and automatically re-insert itself during the next opening cycle, significantly reducing downtime and repair costs.
4. Is the IP65 rating suitable for washdown environments?
Yes, the IP65 rating on the drive and control components makes them highly resistant to water jets from any angle, making this door ideal for food processing facilities and other washdown areas.
5. Can this industrial freezer door handle hundreds of cycles per day?
Absolutely. It is specifically built for high-frequency use in demanding coolroom doors applications, featuring a rugged drive and motor designed for thousands of daily cycles.
