Aluminium and aluminium with epoxy coating.

The Heatex Model L exchanger is characterized 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. The open plate design allows condense water to easy drip off the plates to assure full air exchange.

In- and outlet guides improves the air distribution over the surface and strategic insulation minimize possible temperature conduction within the metal. This way the whole exchanger is utilized to maximum performance for all variation of thermal conditions.
