Introduction
In today’s logistics, cold chain, and industrial warehousing, maintaining energy efficiency and safety during loading and unloading is more critical than ever. Dock shelters play an indispensable role in reducing air leakage, protecting goods, and ensuring workplace safety. Among the various options, the Inflatable Dock Shelter (IDS) has become increasingly popular due to its superior sealing, adaptability to different truck sizes, and long-term cost savings.
Unlike conventional fixed or foam dock shelters, inflatable models use high-strength air bags to expand and form a tight seal around the truck body. This innovative design ensures maximum insulation and minimizes energy loss.
This article explores the design, working principles, updated technical specifications, key advantages, application scenarios, and why NHentrance is a trusted manufacturer of inflatable dock shelters.
Product Overview
An Inflatable Dock Shelter is a flexible sealing solution designed for loading bays, warehouses, and cold storage facilities.
- Installed at the dock entrance, the shelter inflates to tightly seal the gap between the building and the truck.
- Suitable for a wide range of truck heights and widths.
- Provides excellent insulation for temperature-sensitive goods.
- Retracts when not in use, protecting the inflatable cushions from wear and tear.
How Does an Inflatable Dock Shelter Work?
Working Principle
- The truck reverses into the docking position.
- Once in place, the inflatable cushions are activated by an electric blower (0.75kW output).
- Cushions inflate within 20–30 seconds around the truck body, creating an airtight seal.
- During loading/unloading, conditioned air (hot or cold) inside the warehouse is preserved.
- After operations, the cushions deflate automatically.
