Wet surface air coolers
Alfa Laval Wet Surface Air Coolers (WSAC®) are custom built, closed-loop cooling and condensing systems that combine high performance, low operating costs, compact size and reliable operation. Renowned for their robust design and high efficiency, Alfa Laval WSACs are used in a large number of demanding industries. Their low water consumption and high cooling capacity have made them a popular choice in applications where low temperatures are required for process improvements.
- Lowest possible process fluid outlet temperature thanks to evaporative cooling
- Minimal water consumption – cooling water can be re-circulated and the makeup water can be of low quality
- Low energy consumption
- Compact size and lowest lifecycle cost
- Well-proven technology and long service life
Alfa Laval WSAC systems are engineered-to-order, closed-loop cooling and condensing systems. Thanks to Alfa Laval’s WetSurface technology, these units provide maximum cooling in a compact unit and use a minimum of water and electric power. The robust and simple design brings stable thermal performance and low maintenance requirements. An Alfa Laval WSAC is a closed loop system, meaning there is no risk of contaminants entering the process stream.
Our WSAC systems can be fully customized to your requirements, for example they can be designed to withstand corrosive media, cool several process streams in parallel or with the ability to run in both dry-cooling and wet-cooling mode.
