Counterflow
 
Aluminium and aluminium with epoxy coating.

The Heatex Model M exchanger is characterised by the fact that the plates, made of raw or epoxy coated aluminium, are corrugated. Heat transfer is improved by the surface creating turbulence.

The increased turbulence occurs without any filth erecting stagnation points and speed changes. This way the whole exchanger is utilised to the maximum. Model M may be built according to customers request with either double L-flow, double U-flow or L+U-flow configuration.
