Cold curtains

Cold air curtains - an effective barrier against energy losses

Cold air curtains are an irreplaceable solution in commercial and industrial facilities.   They create an invisible air barrier separating the interior from the outside. As a result, they effectively prevent heat loss in winter and cold in summer. At Onninen, we offer a wide selection of cold air curtains from renowned manufacturers.

Our experience shows that a properly selected curtain can significantly reduce energy costs. We often come across questions about the criteria for selecting these devices. The key parameters are the width of the door and the height of the installation. The power of the device and the air flow are also important.

Types of cold air curtains available at Onninen

Our offer includes cold air curtains from leading brands. These are primarily Flowair and Sonniger products. Each of them has its unique features and advantages.   Flowair curtains are distinguished by their modern design and high efficiency.   Sonniger, on the other hand, offers compact solutions ideal for smaller spaces.

Among the available models we can distinguish:

• Cold door curtains for horizontal installation
• Air curtains for vertical installation
• Curtains with heating module (optional)
• Curtains with manual or automatic control

The selection of the appropriate type depends on the specifics of the facility and the client's expectations. Our consultants will be happy to help you choose the optimal solution.

Cold air curtains - how to choose the right model?

There are several key factors to consider when selecting a cold air curtain.   The most important are the dimensions of the door opening and the installation height.   The width of the curtain should be greater than the width of the door. This will ensure full coverage of the opening with the air flow. The mounting height affects the required power of the device.

Other important parameters are:

• Air flow (m3/h)
• Air velocity at outlet (m/s)
• Noise level (dB)
• Possibility to adjust the air flow direction
• Available control options

In everyday practice, we see that the right selection of these parameters is crucial. It allows for achieving optimal efficiency while maintaining user comfort.

Practical applications of cold air curtains

Cold air curtains work well in many types of facilities.   We most often encounter them in stores, shopping malls and office buildings. They are also irreplaceable in production halls and warehouses. Here are a few examples from our experience:

We recently completed a project for a large shopping center. We installed Flowair curtains above the main entrances. The effect was immediate - heat loss decreased significantly. Customers stopped complaining about drafts at the entrance. The owner of the center noted a 15% decrease in heating costs.

Another interesting case was the production hall. Large entrance gates caused problems with maintaining a constant temperature. We used vertical Sonniger curtains there. This allowed forklifts to move freely while limiting heat loss.

In the case of office reorganization, we most often recommend curtains with a heating module. They provide not only an air barrier, but also an additional source of heat. This is an ideal solution for receptions or open spaces with high traffic.

Cold air curtains are an investment that pays off quickly.   In many cases, the payback period does not exceed 2-3 years. Given the rising energy prices, this saving becomes increasingly significant.

At Onninen, we offer not only the devices themselves, but also comprehensive support. Our specialists will help you select, install and configure the curtains. We also provide full after-sales support and service. This gives you the certainty that the selected solution will operate optimally for many years.
