Heat Exchanger Testing

Heat Exchanger TestingAt Thermaflo we not only sell a variety of pasteurisers (HTST using either plate or tubular heat exchangers, batch pasteurisers as well as tunnel pasteurisers) but we also provide full heat exchanger testing for your peace of mind. We provide our clients with one of the most accurate testing methods that will provide you with peace of mind that your equipment is up to food safety standards. To assess the structural integrity of the plates we do what is called a Gas Plate Integrity Test (GPIT). This tells us if your pasteuriser has a leak and in which section it is coming from.

There are four main types of Plate Heat Exchange testing. 

  • Dye Testing
  • Pressure Testing
  • Conductivity Testing
  • Gas Testing

Heat Exchanger TestingAt Thermaflo we mainly use a 'Gas Testing' method which relies on the passage of detection gas across the plate to indicate a leak, with this being read by a detector. This method has little risk of contamination, is rapid and has been shown to be highly accurate.The Gas testing method is most convenient for leak detection in an economic time frame. 

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. The gaskets that we sell are of a very high quality, purchased from a company called Thornhill in the UK. We have had an on going relationship with Thornhill as they have provided us with great customer service and are considered to be a valuable asset to us here at Thermaflo. 

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.
