Lämpööljyä

Lämpööljyä, often translated as thermal oil or heat transfer fluid, refers to specialized liquids used in systems designed to transfer heat. These fluids are crucial in industrial processes where precise temperature control is required, often at temperatures that water or steam cannot efficiently or safely achieve. Lämpööljyä circulates through a closed loop system, absorbing heat from a source, transporting it to where it's needed, and then returning to the source to repeat the cycle.

The selection of lämpööljyä depends on the specific application and operating temperature range. Common types include mineral oils, synthetic oils, and silicone-based fluids. Mineral oils are often the most cost-effective option for lower to moderate temperatures. Synthetic oils offer a wider operating temperature range, greater thermal stability, and improved resistance to oxidation, making them suitable for more demanding applications. Silicone-based fluids are known for their excellent low-temperature properties and stability over a very broad temperature spectrum.

Key properties of lämpööljyä include high boiling point, low vapor pressure, good thermal conductivity, and low viscosity. These characteristics ensure efficient heat transfer, minimize fluid loss through evaporation, and allow for easy pumping. Regular monitoring of the lämpööljyä's condition is important to detect degradation, contamination, or changes in viscosity that could impact system performance and longevity. When lämpööljyä reaches the end of its service life, it must be disposed of in an environmentally responsible manner.
