Freezer high speed doors are specialized rapid doors (What are the types of fast doors?) designed for use in refrigerated and frozen environments, commonly found in logistics and storage facilities. These doors offer the ability to open and close quickly, equipped with specially designed curtains that minimize the exchange of air and heat between the inside and outside. This feature is crucial for maintaining stable indoor temperatures, significantly reducing energy consumption and operational costs.
For those seeking enhanced insulation, we also offer dual-track, dual-curtain cold storage high speed doors, providing superior thermal performance.
Cold storage high-speed doors consist of several key components: tracks, door curtains, fittings, heating wires, motors, and control boxes. These parts work in unison to ensure optimal insulation and energy efficiency during operation.
The tracks are installed vertically on either side of the door frame. Their primary function is to guide the door curtain's movement while securing it in place. Typically made from 1.5mm thick galvanized or stainless steel, tracks are designed to withstand the rigors of cold environments. Stainless steel is recommended for areas with high humidity or corrosive chemicals due to its superior corrosion resistance, although it comes at a higher cost.
The curtain is constructed with an insulated PVC layer, featuring excellent thermal insulation properties. Made of 0.8mm thick PVC fabric, it is durable and filled with high-density rock wool, achieving a total thickness of 20mm. This design effectively blocks the flow of hot and cold air while also reducing noise, enhancing the comfort of the indoor environment. The curtain is connected to the tracks via zippers, ensuring secure installation and ease of removal for seasonal maintenance or cleaning.
The various fittings, including rollers, screws, zippers, and support brackets, connect and secure the components tightly. The curtain's design incorporates zippers along both sides for a snug fit with the tracks. The motor box is securely mounted to the solid shaft connecting to the curtain, ensuring all components work seamlessly for efficient operation.
YUOU freezer high speed doors feature motors from “Baojiu,” a leading brand in the Chinese motor industry. These motors utilize Italian servo technology, ensuring quick response and stable operation in low-temperature environments. Various power options—0.75KW, 1.5KW, and 2.2KW—are available to accommodate different door sizes and weights, with the motors installed at the top left or right of the door.
The control box is designed specifically for the corresponding motor, enabling commands such as opening, closing, and emergency stops. It allows for speed adjustments and supports remote control functionality for added convenience.
Heating wires are installed within the tracks to prevent ice formation due to low temperatures. In cold storage environments, condensation can lead to ice buildup, obstructing door function. These heating elements maintain an optimal track temperature, ensuring smooth operation even in extreme cold conditions, thereby enhancing efficiency and safety while reducing maintenance needs.
When the control box or remote sends an open or close command, the motor receives the signal and begins to operate. The motor's action causes the connected roller shaft to rotate, moving the door curtain along the tracks. The balance system ensures that the door operates smoothly during this process. Integrated heating wires remain active in cold conditions to prevent ice on the tracks, ensuring efficient performance even at low temperatures.
In the event of a power failure, there’s no need to worry. Our cold storage high speed doors come equipped with a manual chain system. Simply pull the chain to operate the door manually, allowing for access without electricity. This feature ensures that your facility remains accessible even during unexpected outages. The design of the emergency chain system is user-friendly, allowing for continued operation until power is restored.
Regular maintenance is essential to prolong the lifespan of cold storage high-speed doors. The door curtain, made of PVC, is water-resistant, fire-retardant, and oil-resistant. Its soft material also offers excellent impact resistance. We recommend regularly checking the curtain for wear and cleaning it with a damp cloth. The tracks and housing are constructed from corrosion-resistant materials, so it's important to protect these components from impacts. Regular inspections for corrosion and wear are advised, along with proper cleaning. Taking good care of your cold storage high-speed doors will extend their lifespan and help lower costs, ultimately boosting your profits.
The installation of a cold storage high speed door typically follows this sequence: installing the left and right tracks, roller shaft, curtain, motor, sensors, and any additional accessories like radar. Detailed installation instructions are available in our instructional videos.
