🔍 Product Overview

The cold storage thermal insulation zipper door is a specialized energy-saving internal fast door designed for cold chain logistics. It effectively reduces air convection, saves energy, and minimizes noise. Equipped with heating and antifreeze devices, it ensures smooth operation in extremely low-temperature environments.

Freezer Door Overview
⭐ Key Advantages
Door Details
Door Mechanism
  • Superior Thermal Insulation: 3mm curtain with thermal PU foam layer (14mm total thickness after processing).
  • High Air Tightness: Advanced top and bottom seals isolate air pressure convection effectively.
  • Wind Resistance: Reaches National Standard Level 8 through precision-matched guide components.
  • Antifreeze System: Integrated heating mechanism prevents guide rail freezing during frequent operations.
  • Rapid Operation: Opening speeds up to 1.2m/s, fully adjustable for efficiency.

❓ Frequently Asked Questions
Q1: What is the lowest temperature this freezer door can handle?
The door is specifically designed for cold storage, operating efficiently in temperatures ranging from -28°C to -1°C, with built-in heating mechanisms to prevent icing.
Q2: How fast does the door open and close?
The maximum opening speed is 0.6-1.2m/s, and the closing speed is no less than 0.6m/s. Both speeds are fully adjustable via the control system.
Q3: What safety features are included?
Standard safety configurations include infrared sensors, pressure airbags, and warning lights. Additional options like safety light curtains and safety edges are also available.
Q4: Does the door lose its position limit after a power failure?
No. Thanks to the full-range absolute value encoder technology and power failure memory function, the door maintains its limit settings even if operated manually while the power is off.
Q5: What are the material specifications for the frame and track?
The door frame is constructed from high-quality Stainless Steel 304, and the tracks are made from specialized polymer materials for high wear resistance and smooth operation.
Q6: How is the door packaged for international shipping?
We use qualified plywood cases for LCL (Less than Container Load) shipments and qualified cartons or pallets for FCL (Full Container Load) to ensure seaworthy protection.
