Prompted by a great and interesting video published by Kaori<\/strong><\/a>, our long partner for brazed plate exchangers<\/strong><\/a>, on its Youtube channel, let\u2019s go talk about double wall heat exchangers<\/strong>.<\/p>\n

Double wall heat exchangers are security type exchangers<\/strong>, having a peculiar construction with a double plate, hence their name \u2018double wall\u2019. This ensures that even in case of breaking or cracking of a plate<\/strong>, due to corrosion or other causes, the mixing between the primary and secondary fluid is avoided<\/strong>.<\/p>\n

This is a kind of construction that can be applied both with brazed plate exchangers<\/strong> and gasketed plate exchangers<\/strong><\/a>, but also in shell and tube exchangers<\/strong><\/a>. This is employed wherever the mixing between the fluids is absolutely to be prevented. That\u2019s the case of food industry<\/a> for example, where products that have to be cooled before bottling, such as mineral water, beverages, milk or wine<\/strong>, don\u2019t have to mix with cooling water, maybe not even potable.<\/p>\n

Further applications are with hydraulic oil<\/strong> and diathermic oil<\/strong><\/a>, where the presence of water within the oil could lead to damages or also be extremely dangerous. The cooling of oil in power converters<\/a> is another application field, where the mixing of oil and water can cause very expensive damages.<\/p>\n
