Alfa Laval - Compabloc


With over 30,000 units handling tough duties worldwide, Compabloc is the market champion when it comes to heat transfer. It is engineered for superior reliability and performance under challenging conditions, with 3-5 times the thermal efficiency of traditional shell-and-tube solutions – along with a compact design that is easy to install and service. For higher pressure demands, the Compabloc+ secures all of these benefits on top of safe operation at up to 60 bar.
