Kølevæsketype

Kølevæsketype refers to the various types of fluids used in cooling systems, particularly in internal combustion engines, to prevent overheating. These fluids are essential for transferring heat away from critical engine components and maintaining optimal operating temperatures. The most common type of kølevæske is based on ethylene glycol or propylene glycol, mixed with water. Ethylene glycol is known for its excellent freeze protection and boiling point elevation properties, making it suitable for a wide range of climates. Propylene glycol, while less toxic, offers similar performance characteristics and is often preferred for applications where environmental or health concerns are paramount.

Other types of kølevæske include water-based coolants without glycol additives, which are primarily used in situations where extreme cold is not a concern and simplicity is desired. These are often seen in stationary engines or specialized industrial applications. More advanced formulations, sometimes referred to as "OAT" (Organic Acid Technology) or "HOAT" (Hybrid Organic Acid Technology) coolants, incorporate organic acids and other inhibitors to provide longer service life and enhanced protection against corrosion and scale formation. These advanced types are typically used in modern vehicles designed for extended coolant change intervals. The specific type of kølevæske required for a vehicle or piece of equipment is usually specified by the manufacturer to ensure compatibility with the cooling system's materials and to achieve the desired performance. Using the incorrect type of kølevæske can lead to decreased cooling efficiency, corrosion, and potentially severe engine damage.
