Description
Product Description
FUCHS FRICOFIN HDD-PG 50 is a premium ready-to-use propylene glycol (PG) heavy-duty engine coolant designed for diesel engines, mining equipment, construction machinery, agricultural machinery, forestry equipment, marine engines, and stationary power generation systems. This ultra-high-performance low-toxicity coolant provides long-life protection against freezing, overheating, corrosion, and cavitation, especially in heavily loaded diesel engines and environmentally sensitive applications.
FUCHS FRICOFIN HDD-PG 50 is formulated using propylene glycol technology with low-silicate coolant additives and is supplied as a fully formulated 50% premixed coolant, ready for direct use without further dilution. The formulation is free from amines and phosphates and provides reliable protection for all cooling system metals, especially aluminium components, while offering improved environmental safety compared with conventional ethylene glycol coolants.
