I. Product Name

Double-acting Impact Door

II. Product Introduction

Double-acting Impact Door (also known as a free door or impact door) requires neither manual operation nor motor drive. It opens bidirectionally upon impact from external forces such as personnel, forklifts, or goods, and automatically returns to its closed position after release. This door occupies no entry/exit space and is easy to operate, making it the ideal solution for cold storage facilities, cold chain workshops, and logistics warehouses where goods are frequently moved and forklifts operate continuously. It significantly enhances operational efficiency and prevents traffic congestion.

The door panel features integrated high-density polyurethane foam, offering exceptional thermal insulation that effectively prevents heat loss. Available in standard thicknesses of 100mm, 150mm, and 200mm, it can be flexibly selected according to the required temperature range for various cold storage applications, including fresh-keeping, refrigeration, and freezing systems.

The panel is available in materials such as 304 stainless steel or color-coated steel plate. The door frame undergoes anti-corrosion and low-temperature treatment, offering resistance to moisture and aging, making it suitable for the specialized environment of cold storage facilities while balancing durability and practicality. Customization options are available as needed.

The dimensions are customizable, with standard door openings available in 1.2×2.1m,1.5×2.2m, and 1.8×2.4m sizes. Both single and double doors can be customized to fit various cold storage door openings, meeting the requirements for forklift and cargo access.

III. Product Features

1. Collision safe reset for efficient passage: Bidirectionally open automatically without manual operation; forklifts and goods can pass immediately upon impact. Automatic reset upon release eliminates waiting time, significantly enhancing cold storage operational efficiency and making it ideal for high-frequency access scenarios.

2. Sealed insulation for energy efficiency: The door body fits precisely with the door frame, equipped with low-temperature resistant sealing strips that ensure tight closure, effectively minimizing cold leakage, stabilizing warehouse temperature, and reducing cold storage energy consumption.

3. Durable and impact-resistant with long service life: Featuring high-strength door frames and thickened door panels, equipped with a premium spring reset system, it exhibits exceptional impact resistance, allowing rapid restoration without deformation after impacts; the hardware components are treated with anti-corrosion and low-temperature protection, making them suitable for humid and low-temperature environments in cold storage facilities, ensuring superior durability.

4. Safe and convenient, maintenance-free: Free from complex drive mechanisms, featuring simple operation and requiring no dedicated maintenance personnel; designed without sharp edges and equipped with cushioning devices to prevent injuries to personnel, cargo, and the door structure during impacts, ensuring enhanced safety.

5. Flexible customization with broad adaptability: Dimensions, panel materials, and door thickness can be customized according to requirements, making it suitable for cold storage facilities in various industries such as food, pharmaceuticals, and cold chain logistics, while balancing practicality and compatibility.
