What is PEKASOL® FG?

Product description

PEKASOL® FG is a refrigeration and heat transfer fluid based on 1,2 propylene glycol for food processing and food manufacturing companies with NSF International approval. It is a colourless and odourless heat transfer fluid based on non-toxic and environmentally friendly monopropylene glycol, especially for the food industry and all applications where food quality is important.

The inhibitors reliably protect all materials commonly used in plant construction against sludge formation and corrosion. PEKASOL® FG is certified by NSF under HT1 in various ready-to-use dilutions and is offered exclusively in these concentrations. All ingredients are listed and approved by the FDA as food additives. Thus, in the event of an accident, the contamination of food products with the antifreeze is absolutely harmless and a health hazard in the event of unintentional consumption is excluded.

PEKASOL® FG is free of nitrite, amine, borate, silicate and nitrate.

Instruction for use

One product for heating systems and cooling systems

PEKASOL® FG can be used both in heating systems and in cooling systems. Depending on the concentration, the operating temperatures range from -40 °C to +120 °C. All ready-to-fill dilutions supplied by us are diluted with deionised water (demineralised water). In order to ensure sufficient corrosion protection, the concentration should not fall below 26 % by volume. Only PEKASOL® FG must be used for refilling and concentrating, otherwise the NSF approval expires.PEKASOL® FG is suitable as an antifreeze additive for heating systems according to VDI 2035.

Learn more about the correct application of Pekasol FG® in our product brochure.
