After working with customers who need assistance selecting heat exchangers for corrosive environments such as those with high concentrations of ammonia, vinegar, smoke or other environmental conditions that attack metal, Hans Güntner GmbH, Fürstenfeldbruck, Germany, has compiled corrosion protection variants for its heat exchangers.
The “selection assistant” document discusses how ambient conditions in the refrigeration room must be taken into consideration when a heat exchanger component is selected. It also contains a summary of cases that require special corrosion protection and covers suitable combinations of materials for heat exchangers. For ease of use, the material is broken down into core tube, fin, end plate, housing and tray, so users can put together the proper combination of materials that suit. The document can be downloaded from the web site at www.guentner.de.
