Blower

When a refrigerated or freezer truck is opened at the loading dock, a significant temperature difference arises within seconds between the warehouse air and the vehicle interior. The result: moisture condenses into water droplets, ice forms on doors and goods, and temperature-sensitive cargo suffers from thermal stress. Our blower efficiently solves this problem: it is mounted next to the industrial door on an adjustable arm and creates a directed air curtain that gently channels warehouse air into the cargo area—or vice versa—to equalize temperature differences in a controlled and gentle manner.

Although the unit is simply called a “blower,” it operates on the principle of a mobile air curtain: it generates a wide, uniform airflow that acts like an invisible barrier. Unlike fixed systems installed above the door, our blower is flexibly positionable—ideal for the dynamic workflow of loading and unloading. The airflow is precisely directed toward the open truck door, ensuring that air exchange occurs exactly where needed—without affecting the broader warehouse environment.

Thanks to the blower, there’s no need to wait slowly for temperatures to naturally balance. Instead, equalization happens in parallel with the loading process—without downtime, yet with significantly reduced risk of condensation, icing, or quality loss. This is especially crucial in food, pharmaceutical, or chemical logistics, where it provides a clear advantage for quality assurance and compliance. Even with frequent loading cycles, product integrity remains intact, as sudden thermal shocks are avoided.

Without active equalization, the warehouse climate control system must expend large amounts of energy after each loading cycle to restore indoor conditions. Our blower minimizes this effect: by exchanging air only where necessary, the rest of the warehouse climate remains stable—and your heating or cooling costs decrease over time. This targeted climate management has a measurable impact on operational expenses, especially during periods of high loading frequency or extreme outdoor temperatures.

The blower is designed as a standalone unit and is mounted beside the door on an adjustable arm. It requires no connection to the door control system and can be easily installed on standard industrial doors—making it ideal for retrofitting in existing facilities. Manual adjustment of the arm allows quick adaptation to different vehicle sizes and loading scenarios. Operation requires no special training and can be intuitively handled by truck drivers or warehouse staff.

As part of our accessory range for industrial doors and loading docks, the blower precisely complements your technical equipment wherever climate control and process reliability must go hand in hand. Weglehner offers you this practical tool as a durable solution for daily use—custom-fit, functional, and manufacturer-independent. It is particularly well-suited for distribution centers, food logistics, pharmaceutical warehouses, or any facility where temperature-controlled goods are regularly loaded or unloaded.

With this blower, you not only enhance the quality of your logistics processes but also contribute to energy efficiency and workplace safety at the loading dock—all without costly retrofits or complex additional systems.
