Unlike conventional heat transfer fluids, the Paratherm NF will not cause hard carbon formation on heated surfaces. Conventional heat transfer fluids, when severely overheated, will produce sooty carbon at the film layer. Much of this carbon immediately adheres to the heated surface and bakes on, forming a crust. As layer-upon-layer builds up, heat transfer - and in many cases flow - is impaired. Although nearly impossible to remove without scraping, sandblasting or using chlorinated solvents, the carbon can ultimately break loose, and large chunks of it can circulate through the system impeding flows and fouling components. Where fouling is extreme, heater tubing and electrical elements will stress and prematurely fail. Under similar extreme overheat conditions, the NF fluid evolves small carbon granules. These granules remain in suspension and are easily filtered out.
