Air-cooled Screw Chiller
Understanding the Technology

What is an Air-Cooled Screw Chiller? Simple Explanation

First, let's understand what an Air-cooled Screw Chiller actually does. Simply put, it's like a giant air conditioner that works both ways. During summer, it removes heat from your building. However, in winter, it pumps heat into your building.

Unlike traditional systems, our Air-cooled Screw Chiller uses outside air to work. Therefore, you don't need expensive cooling towers. Additionally, you don't need a special machine room. As a result, installation becomes much easier and cheaper.
