PETRO-THERM™ is a general purpose heat transfer fluid developed for use in non-pressurized, liquid phase, closed heat transfer systems operating with bulk temperatures up to 315°C (599°F). It is specifically formulated to provide economical service in a variety of industrial applications while resisting oxidative and thermal degradation. Please contact a Petro-Canada Lubricants Technical Service Advisor for any questions.

PETRO-THERM™ is particularly suitable for use in asphalt plants, marine applications, wood processing, dry kilns, institutional laundry and heating, and general processing.

CALFLO™ Cleaning Fluid is specially designed to help clean dirty or heavily carbonized systems which have been operating on overextended, contaminated or degraded heat transfer fluids. The cleaning action of this fluid is based on its solvency and the fluid should therefore be used in its pure, undiluted state. This fluid is recommended for use in closed heat transfer systems and should not be used in systems operating in food processing plants. The upper operating limit for CALFLO™ Cleaning Fluid is 100°C (212°F) and therefore should not be placed into an existing system while in operation warmer than this temperature. CALFLO™ Cleaning Fluid is NSF registered HT1 suitable for use in food processing facilities where there is a possibility of incidental food contact. Once all the cleaning fluid has been drained, CALFLO™ Flushing Fluid should be used to help remove residual fluids and loose contaminants prior to recharging the system with new heat transfer fluid. PURITY™ FG WO white mineral oil should be used in food processing facilities as the flushing fluid. Please refer to Tech Bulletin (TB-1158) for detailed instructions on how to clean heat transfer systems.

CALFLO™ Flushing Fluid is a clear fluid designed for flushing out dirty oil-circulating systems including those operating on heat transfer fluids. This fluid is also recommended to flush debris and water from pressure tests and contaminants from welding and construction in newly commissioned heat transfer systems. While it will not remove hard baked-on carbon, nor will it dissolve heavy sludge residues left by highly degraded fluids, it is effective in removing trapped residual fluids and in displacing system contaminants such as water, loose solids and debris. For heavily contaminated systems, CALFLO™ Cleaning Fluid should be used first. It operates effectively as a mechanical flushing agent for heat transfer systems changing over to CALFLO™ or PETRO-THERM™ heat transfer fluids from other non-compatible materials. It is completely compatible with hydrocarbon based lubricants and with all grades of CALFLO™ or PETRO-THERM™. For systems that will subsequently operate on a low viscosity fluid, please consult Technical Services. For systems in food processing plants where an HT-1 approved fluid will be used, flush with PURITY™ FG WO white mineral oils.
