Organic Anti-Freeze reliably protects drinking water and toilet systems from frost damage – completely free of toxic additives. The formula is based on highly pure monopropylene glycol (MPG) in USP quality, derived from plant-based glycerin. This makes the product especially suitable for sensitive systems such as fresh water tanks, pipes, pumps, valves and seals in boats, motorhomes, caravans or tiny houses. It ensures effective protection while providing excellent material compatibility.
Plant-based & high purity
The contained propylene glycol is produced by catalytic hydrogenolysis from distilled glycerin. With a purity level of over 99.5%, it meets the requirements of the pharmacopoeias (USP/EP). This quality reduces unwanted impurities and results in a low-odour, colourless and system-friendly product.
Efficient & versatile
The ready-to-use mixture can be diluted further if needed to increase the application volume. After the season, the antifreeze can be easily reused following proper draining and storage. As no additives for self-preservation are included, the product offers an especially natural solution.
Also suitable for use in the external cooling circuit.
