HYAC hybrid air coolers

Combining traditional air cooling and closed-loop evaporative cooling, Alfa Laval hybrid air coolers (HYAC) offer reliable and effective cooling for a range of industrial applications. By switching cooling modes to match the natural temperature cycles of the ambient air, an Alfa Laval HYAC takes advantage of the cooling possibilities offered by nature on any given day to optimize water and electricity consumption, while maximizing cooling capacity.

Built for sustainability and performance

  • Fully customized to your operating conditions and requirements
  • Robust, industrial-grade equipment with outstanding performance over time
  • Exceptional cooling performance and minimal water consumption
  • Compact size, making it possible to upgrade cooling capacity even where available space is limited
  • Low energy consumption

Alfa Laval HYAC systems offer compact and sustainable cooling for plants requiring high cooling capacity and low water consumption. A robust and straightforward design ensures stable operation for many decades and minimal maintenance, keeping total cost of ownership low.

These systems are ideal for liquid and gas cooling, as well as condensing duties, in industries such as oil & gas, refinery, petrochemicalssteel, pulp & paper, thermal power and renewable power.
