Tight-Sealing Freeze Door Technology
Rapidor® Freeze 2 fabric roll up doors combine fast cycling with high-energy insulation and sealing. The result is improved efficiency, lower energy cost and increased safety. Freeze 2 has two curtains that roll simultaneously creating a controlled air space when closed, the side frames are heated and minimize condensation on the door. Ideal for temperatures down to -20 °F (-28.9 °C) with no more than a 70 °F (21°C) temperature difference across the door. For use in indoor applications.
The door curtains are fabricated of reinforced PVC, with flexible weighted soft-bottom edges. The edge of the curtain has injection-molded teeth that move up and down in a self-lubricating polyethylene track attached to structural galvanized side frames. The drum and shafts are made of galvanized steel. Both the drum and the motor have galvanized covers. The standard motor is IP 54 2HP, with an incremental encoder mounted to the drum shaft to provide precision motor and door opening feedback.
An infrared photocell NPN, IP67 is installed on the inside of the side guide and detects the presence
of a pedestrian or vehicle. A bottom edge detector reverses the door when it hits an obstacle during the closing cycle. This detector can be either a wireless safety edge or a sensor that determines if the fabric can unroll properly. All hardware has protective coating against corrosion.
Safety
The curtain can withstand forklift impact, which minimizes maintenance and downtime while maintaining a tight seal over the life of the door. Additionally, the reduction in frost build up improves safety on the floors for maintenance and production workers. The use of vision panels provides added safety in high production environments. A bottom edge detector reverses the door when it hits an obstacle during the closing cycle.
