Note
the contents of the heat transfer medium should comply with Vdi guideline 2035 on damage and scale deposit formation in
warm water heating systems.
For industrial and long-distance energy systems, see the applicable codes VdtÜV 1466 and aGFW FW 510. Mineral oils in the
heat transfer medium or lubricants containing mineral oils of any type lead to strong swelling and in most cases cause ePdM
seals to fail.
When using nitrite-free frost and corrosion resistance solutions with an ethylene glycol base, pay close attention to the details
outlined in the manufacturers‘ documentation, particularly details concerning concentration and specific additives.
