Recommendations
for Material Selection
Gntner Knowledge for Different Applications and Ambient Conditions
Avoid corrosion
by selecting the ideal material
In this brochure we compiled the most important application situations where a special corrosion protection is required. We give
recommendations concerning the optimal
material selection for your Gntner heat exchanger.
This brochure helps you to determine the
specific material combination, corresponding
optimally to your application situation.

Exclusion of liability:
These recommendations for material selection of heat exchangers reflect our experiences. They can neither replace the assessment of the installation situation and location by experts nor the assessment of possible corrosion attack.
The recommendations are merely intended for technical information purposes. We assume no liability for the completeness and correctness of the indications. The information is intended to support the technical assessment of the installation situation and location.
This table compares the corrosion resistance of both technologies for frequently occurring application locations and categorises their corrosion resistance.
