Welded Plate and Block Heat Exchanger

Alfa Laval Compabloc range is compact and designed for optimum performance and serviceability across a broad spectrum of industrial process applications. Standard pressure range up to 42 bar.

The Alfa Laval Compabloc is a breakthrough plate heat exchanger design that combines a whole range of technological advantages into one compact unit. The all-welded plate pack does away with all gaskets between plates, and makes it possible to operate with a wide range of aggressive media and at high temperatures and pressures.

Corrugated plate patterns generate high turbulence that results in overall heat transfer coefficients three to five times greater than a shell-and-tube heat exchanger. In addition to minimizing fouling, this makes it financially viable to use corrosion-resistant exotic metals.

This makes the Compabloc perfect for heat recovery in corrosive operating environments and for handling aggressive, high-temperature fluids of all kinds. The compactness of this all-welded unit means it can be installed virtually anywhere – as a condenser or reboiler for distillation and stripping columns, as a condenser on top of reactors and in a wide range of other heat exchanger applications.
