Alfa Laval HYAC hybrid air coolers save water and increase cooling capacity. On nature’s terms. Alfa Laval HYAC DZ is uniquely designed with both dry and wet zone cooling. Process fluids are pre-cooled in the dry zone, followed by final cooling in the wet zone where drenching water is sprayed over the tubes initiating the evaporative cooling effect to achieve the final process outlet temperature. Alfa Laval HYAC DZ, with two cooling zones allows for hotter process- inlet temperatures while still achieving low outlet temperatures. This is accomplished by finned tubes in the dry zone and bare tubes in the wet zone. And provides plume mitigation on the evaporative cooling zone which will reduce ice buildup in the surrounding area. Alfa Laval HYAC hybrid air coolers save water and increase cooling capacity.
