FULL OF FEATURES

High‑temperature resilience and integrated filtration

High‑temperature resilience - This feature clearly distinguishes the range. All KWD‑BH models maintain efficient drying performance even when inlet temperatures reach 80 °C. This capability is enabled by proven refrigerants, reinforced heat‑exchange components, and stable cooling‑cycle control, ensuring continuous protection and effective humidity management under high thermal loads.

 

Integrated filtration - Each unit includes an internal 5/1 µm filtration configuration to enhance air purity before distribution. This filtration stage captures moisture and particulates, reducing stress on downstream equipment and minimizing component wear. The integrated design simplifies installation and maintenance by eliminating the need for separate pre‑filter housings in many applications.

Why the KWD-BH series stands out

The KWD-BH series is the preferred choice for industries that require reliable performance at high inlet temperatures. Its optimized refrigeration system, integrated filtration, and high mechanical durability ensure consistent drying quality with reduced maintenance. With capacities suitable for a wide range of installations, it protects equipment and improves air system reliability, making it a highly versatile and safe choice for harsh environments.

MORE FEATURES

Different refrigerants and easy condensate control
