Airwall provides cold insulation

Airwalls increase efficiency of cold insulation

Air-conditioning is energy-intensive: according to the U.S. Energy Information Administration, about 10 percent of the total electricity consumption in the US is used for cooling. In addition to the high electricity consumption, doors and gates are often left open for the expensively cooled air.

Depending on the operation, however, entrances cannot remain permanently closed. Employees have to get to other parts of the production facility, trucks are unloaded and process cooling has to be available all year round. So how do you separate cooled indoor air from warm outdoor air? With a precise barrier of air.

Why cold insulation is important

Heat and warmth can become decisive cost factor: Excessively high working temperatures stress employees, can impair the service life of machines and air-conditioning systems have to work under load to counteract. Building service operating costs rise as a result, while the actual cooling effect evaporates. Refrigeration causes about ten per cent of global CO2 emissions.

So keeping warm air outside by cold insulation is not only advisable for reducing operating costs, it also helps achieve sustainability goals.

More efficient air conditioning and cooling systems are only one key to success. Likewise, consistent insulation is essential to maintain the desired room temperature. However, even the best insulation is of little help if doors or gates have to be open due to ongoing operations, causing cooled air to heat up.

Airwalls: a custom-fit solution for every passageway

There are several ways to insulate against cold. Often, plastic strip curtains are used to reduce an outflow of cool air to the outside. While the curtains are a cost-effective solution, the bulky plastic pieces are often in the way, difficult for vehicles to pass and fundamentally inefficient at sealing.

Airwalls offer custom-fit solutions for every door and gate. Our systems accelerate air and can thus precisely separate layers of air from each other. The airwall keeps cooled air in the building, but at the same time allows unhindered passage of employees and vehicles. Optionally, our airwalls can also be equipped with cooling coils so that they themselves become an integral part of a cooling concept. Even trucks with refrigerated boxes can be effectively protected against heat with our Airwall Move.

What our airwalls can do:

  • reduce energy consumption
  • keep heat in the places where it is needed
  • seal access points without making them impassable for employees
  • increase well-being in the workplace
  • can themselves become part of the heating system with heating registers

What is an airwall and how does it work?

Airwalls are systems that accelerate air to high speeds with the help of fans and compress it into a thin jet via a patented nozzle (pressure linear module). The generated air jet prevents layers of air from mixing. Our units can be mounted on the side of gates or above doors. The air jet then separates the air over the entire height. This keeps cold air outside in winter, for example, and does not cool the air indoors. Airwalls are modular and therefore have a lot of planning freedom. They can therefore also be retrofitted without any problems.
