Product Introduction
This Zipper Insulated High Speed Door is an indoor high-speed door specially designed for cold storage scenarios. It adopts a core PU foam insulated curtain (total thickness about 10mm) composed of three layers of 0.8mm base material and two layers of filler, paired with zipper-type patented track technology. It achieves high airtightness and extreme energy saving, with a door opening speed of up to 2.4m/s and closing speed of 1.2m/s. The high airtightness effectively reduces the exchange of cold and hot air inside and outside the cold storage, minimizing cold loss. It supports multiple intelligent opening modes (manual button, geomagnetic induction, radar, remote control, linkage interlock), and is widely used in cold chain logistics, food processing, pharmaceutical refrigeration and other cold storage scenarios.
