Bolztherm System Cleaner 20

BOLZTHERM® System Cleaner 20 is a synthetic cleaning fluid specially developed to remove residues from closed heat transfer systems that are caused by thermal decomposition or oxidation of heat transfer fluids. Thanks to its powerful formulation, soft carbon deposits and oxidised residues are reliably dissolved. The high thermal stability of BOLZTHERM® System Cleaner 20 allows short-term heating to up to 300 °C without forming decomposition products. This property, combined with a high flash point, contributes significantly to the safety of the system.
