Explanation of the combination of industrial doors and inflatable door seals1

1. System composition and function
(1). Core equipment
◦ Industrial doors: Commonly used types include electric sliding doors, fast rolling doors or hydraulic lift doors, which are responsible for quickly opening and closing the door openings to ensure logistics efficiency.
◦ Inflatable door seal: It is composed of top and both sides of the airbag, blower, PVC cord (or polyester fiber shading) and control system, and is sealed by inflating and expanding the truck bed
◦ Auxiliary equipment: It is necessary to match the loading and unloading platform (adjust the height difference between the carriage and the warehouse) and the wheel guide rail (to position the vehicle) to form a complete loading and unloading system.

(2). Principle of synergy
◦ Loading and unloading process:
◦ Vehicle in position: The truck reverses to the door seal area, and the wheels are fixed by the guide rails.
◦ Airbag inflation: The blower is activated (about 40 seconds), and the airbag expands close to the surrounding area of the cabin, forming a confined space
◦ Job completion: After loading and unloading, the airbag is deflated and contracted, the vehicle leaves, and the door seal is reset.
◦ Sealing mechanism: The airbag is mostly made of wear-resistant Cordura fabric (tensile strength > 290N/mm²), and is combined with polyurethane foam door panel to block the convection of internal and external air and prevent cold air leakage and dust/insect infestation

2. Key application scenarios and advantages
(1). Cold chain logistics
◦ Thermal insulation and anti-condensation: the door seal blocks the external hot air from entering the cold storage, maintains the ambient temperature of -35°C~70°C, and avoids frost in the loading and unloading area
◦ Energy saving and consumption reduction: reduce the loss of cold air, reduce the load of refrigeration equipment, and save more than 30% of energy consumption
(2). Dustproof and anti-pollution environment
◦ In scenarios such as precision electronics and pharmaceutical warehousing, the sealing design effectively isolates dust, rain and foreign matter
(3). Severe weather adaptability
◦ It can still operate normally in rain, snow, wind and sand, and the tear resistance of the airbag ensures long-term durability

Q1: What are the main benefits of combining industrial doors with inflatable seals?

A1: The key benefits include:

• Enhanced sealing performance - Creates an airtight barrier against dust, insects, and air leakage

• Improved energy efficiency - Significantly reduces thermal transfer in temperature-controlled environments

• Better environmental protection - Prevents contamination in cleanrooms and food processing areas

• Increased durability - Reduces wear on door edges and frames

Q2: How does the inflation/deflation mechanism work with industrial doors?

A2: The system operates through:

1. Automatic inflation when the door closes, using built-in air compressors

2. Instant deflation when opening to allow smooth door operation

3. Pressure sensors that maintain optimal seal tightness

4. Quick-response valves for rapid inflation/deflation cycles

Q3: What maintenance do inflatable door seals require?

A3: Maintenance involves:

• Regular cleaning of seal surfaces

• Periodic inspection for wear or damage

• Lubrication of moving parts (if applicable)

• Air system checks for compressor performance

• Visual inspections of the seal's inflation pattern

Q4: Can inflatable seals be retrofitted to existing industrial doors?

A4: Yes, in most cases they can be added to:

• Roller shutter doors

• Sectional overhead doors

• High-speed doors

• Swing doors Retrofitting requires professional assessment of door structure and operating mechanism.
