CROSSFLOW FEATURES

All Heatex crossflow heat exchangers share these features:

  • Extruded aluminum corner profiles (stainless steel is optional).
  • Double-sealing concept to avoid leakage and contamination, which means both gluing and a mechanical fold.
  • Heatex’s corrugation pattern increases turbulence and heat transfer without creating stagnation points.
  • End plates with flat or folded edges for all mounting interfaces.

Depending on the application, you might need a certain crossflow model, including options.

OPTIONS

Besides being able to configure each heat exchanger in numerous ways in terms of size and performance requirements, we offer a wide range of options to suit various applications.

Corrosion Protection

We recommend adding epoxy-coated heat transfer plates, a corrosion-protected framework, and lacquered plate edges for improved corrosion protection in demanding applications such as in coastal environments.

Dampers

Dampers are useful for protecting the heat exchanger when the heat exchanger approaches the freezing point. Heatex dampers are suitable for close/open bypass exchanger sections connected to a crossflow plate heat exchanger.

Extra Tightness

Heatex offers a process to fill all plate crevices with a special polymer for water tightness and an even higher level of air tightness. This will result in a highly tight heat exchanger suitable high humidity or direct water exposure.

FAQ & DOCUMENTS

How does a crossflow heat exchanger work?

In a crossflow heat exchanger, the cold and the warm air flow perpendicular to each other. Two neighboring aluminum plates create channels for the air to pass through. The supply air passes on one side of the plate and the exhaust air on the other. The heat in the exhaust air is transferred through the plate from the warmer air to the colder air.

A very important parameter for the performance of a plate heat exchanger is the spacing between the plates. A narrow channel leads to high-pressure drop but also to high efficiency. The latter means that more heat is transferred to the cold side. A higher plate distance is better if a lower pressure drop is required. The trade-off is lower efficiency.

Usually, the exhaust air is contaminated with humidity and pollutants, but with a plate heat exchanger, airflows never mix, leaving the supply air fresh and clean.
