Door Structure and Design for Food Cold Storage

The semi-recessed structure allows the door leaf to align closely with the cold room

The door leaf is filled with flame-retardant polyurethane insulation with a density of 40kg/m³ ±2, providing excellent thermal resistance for food cold chain storage. Multiple door thickness options, including 75mm, 100mm, 120mm, and 150mm, allow the door to be matched precisely to different temperature zones.

This insulated freezer door is suitable for environments ranging from chilled storage to ultra-low temperature freezer rooms down to -45°C, ensuring reliable performance even in demanding food storage conditions.

Product Specifications

Door Panel and Food-Grade Surface Materials

The door panel is constructed using PVC plastic profiles with a smooth and hygienic surface, making it suitable for food storage environments where cleanliness is critical. For higher hygiene standards or frequent washdown areas, optional 304 stainless steel facing is available.

Additional surface options such as color steel or embossed aluminum plates provide durability and corrosion resistance for different food cold storage applications.

Heated Door Frame and Anti-Freezing System

The aluminum alloy door frame can be equipped with three-sided or four-sided heating to prevent ice buildup and door freezing in low-temperature food cold rooms. This heating system ensures smooth door operation and minimizes downtime caused by icing.

For ultra-low temperature or high-humidity environments, an optional heated threshold can be added to further improve reliability in frozen food and blast freezer applications.

Sealing and Airtight Performance

High-quality EPDM sealing strips combined with PVC magnetic sealing ensure tight closure and excellent airtight performance. This sealing system effectively reduces cold air leakage, moisture infiltration, and frost formation, helping maintain consistent storage conditions and protect food quality.

Hardware and Safety Configuration

The door is equipped with low-temperature-resistant hardware made from zinc alloy, stainless steel, and nylon components, ensuring stable operation in freezer environments. An internal push rod and emergency release handle allow safe exit from inside the cold room, meeting safety requirements commonly required in food cold chain facilities.

Typical Applications in Food Cold Chain Storage

The semi-recessed cold room door is commonly used in frozen food and ice cream cold storage rooms, meat and poultry freezer rooms, seafood and aquatic product storage, dairy product cold rooms, food processing and packaging facilities, and cold chain logistics and distribution centers.

Key Advantages for Food Cold Chain Facilities

This door design helps improve temperature stability, reduce energy consumption, and lower long-term operating costs in food cold storage facilities. The flush-mounted structure supports hygiene management and easy cleaning, while the heated frame and reliable sealing system ensure consistent performance in high-use and low-temperature environments.

Frequently Asked Questions

Is a semi-recessed cold room door suitable for food cold storage?
Yes. Its insulation performance, airtight sealing, and hygienic surface options make it ideal for food cold chain applications.

What door thickness is recommended for frozen food storage?
For frozen food and freezer rooms, 100mm or thicker door panels are recommended to ensure sufficient insulation.

Is a heated door frame necessary for food freezer rooms?
For temperatures below -18°C, a heated door frame is strongly recommended to prevent icing and ensure smooth operation.
