The Grant Solar Fluid (Glycol) – 10 Litre (Part No. GS222075) is a specially formulated heat transfer fluid designed for use in solar thermal systems. This fluid ensures efficient heat transfer and system protection, particularly in colder climates.​

Key Features:

• Composition: A non-toxic 40/60 propylene glycol and water solution, free from nitrates, phosphates, and ammonia, making it environmentally friendly and safe for potable water systems. ​

• Freezing Protection: Formulated to prevent freezing, ensuring reliable operation of solar thermal systems even in sub-zero temperatures. ​

• Corrosion Inhibition: Includes additives that protect system components from corrosion, extending the lifespan of the system. ​

• Compatibility: Compatible with most other heat transfer fluids based on propylene glycol, and suitable for use with European hard tap waters up to a hardness of 30° dH. ​

• Volume: Supplied in a 10-litre container, ideal for refilling or topping up solar thermal systems.​

This solar fluid is essential for maintaining the efficiency and longevity of solar thermal systems, particularly in regions with cold climates.
