👉 The GC fluid, or glycol coolant fluid, is a crucial component in various cooling systems, particularly in automotive and industrial applications. It's a specialized antifreeze solution that circulates through heat exchangers, absorbing excess heat from components like engines and radiators to prevent overheating. The fluid's unique properties, including its high boiling point and low freezing point, ensure efficient heat transfer even under extreme temperature conditions. This prevents damage to components and maintains optimal operating temperatures, thereby enhancing system performance and longevity.
