Proven cooling
Efficient heat removal
Multi‑pass cross‑finned tubes maximize surface contact, rapidly lowering discharge temperatures for dependable drying.
Durable
Built for heavy duty
Rugged metal construction and proven thermal design ensure stable performance even in tough industrial environments.
Versatile
Wide range coverage
Models from 2.2 to 140 Nm³/min cover small workshops to large plants, ensuring consistent air cooling at any scale.
Cross finned cooling technology
At the core of the AT‑A series is KyungWon’s multi‑pass cross‑finned tube heat exchanger. This configuration increases surface area and directs air across multiple cooling stages, resulting in rapid temperature reduction and effective moisture condensation. Combined with a wide thermal operating range and stable pressure handling, this technology ensures consistent cooling performance even under fluctuating compressor loads and high‑temperature conditions.
Why the AT-A series stands out
The AT‑A series is designed to deliver dependable cooling across a wide range of compressed air installations. With broad capacity coverage, robust heat‑exchanger technology, and compatibility with various compressor configurations, it ensures stable air temperatures and enhanced protection for downstream equipment. Durability, flexibility, and proven performance make the AT‑A series a reliable solution for long‑term industrial operation.
