  5. Heat Exchanger Testing

Our Heat Exchanger testing uses accurate testing methods that will provide you with peace of mind that your equipment is up to food safety standards.


There are three main types of Plate Heat Exchange testing. 

  • Dye Testing
  • Pressure Testing
  • Gas Testing


At Thermaflo our primary testing method is by gas testing, which relies on the passage of detection gas across the plate to indicate a leak, with this being read by a detector. 

To assess the sealed integrity of your heat exchanger, we prefer using the gas testing method for a number of reasons. It is relatively fast, does not contaminate your equipment, detects the smallest of hairline fractures that other leak tests wouldn’t pick up and works on all types of heat exchangers.


If there is an issue with your heat exchanger, we are able to supply the necessary plates or gaskets that are needed to fix any problem at a very competitive price.


After your machine has been fixed, we will then run through the test again to make sure that your machine is running at 100% and that there are no further problems
