Production of plate heat exchangers that are used to heat up cold liquids and to cool off warm liquids without the two liquids coming into contact.
The steel start and end plates in these heat exchangers are cut to size by De Boer Snijbedrijf. The tolerance for the cut holes is 0.5 mm, and so the cutting process has to be extremely precise. De Boer Snijbedrijf also blasts the cut parts and applies red lead to them
