Servo Therm Medium is a premium-grade heat transfer oil developed from specially refined mineral base oils to deliver outstanding performance in industrial heat transfer systems. It is engineered to provide excellent thermal and oxidation stability, ensuring consistent and reliable heat transfer efficiency across a wide range of industrial applications. Designed to perform under continuous high-temperature operations, this oil guarantees long service life, reduced maintenance, and superior operational reliability. The advanced formulation of Servo Therm Medium allows it to withstand temperatures up to 300°C in well-designed heat transfer systems without undergoing thermal degradation or deposit formation. Its low volatility minimizes oil loss through vaporization, ensuring sustained efficiency and reduced top-up requirements during long-term operation. In addition, its low vapor pressure and high thermal conductivity help maintain stable and uniform heat transfer, improving process control and energy efficiency in heating systems. One of the key strengths of Servo Therm Medium is its exceptional oxidation stability, which minimizes sludge and carbon deposit formation even under severe thermal stress. This ensures that pipelines and heat exchangers remain clean, allowing for optimal heat flow and improved equipment life. Its inherent resistance to oxidation and cracking significantly extends the oil’s operational lifespan, reducing downtime and fluid replacement costs. Formulated to meet the demanding needs of modern industrial operations, Servo Therm Medium is recommended for a wide range of applications, including chemical processing, textile drying, rubber and plastic molding, and other industries where precise temperature control is critical. Its consistent viscosity and superior film strength ensure reliable pumpability and efficient circulation even at elevated temperatures. With its combination of low volatility, excellent oxidation stability, and long-lasting thermal performance, Servo Therm Medium stands as a dependable choice for industries requiring uninterrupted heat transfer efficiency and cost-effective operation.
Before charging the heat transfer system with Servo Therm Medium oil, the system must be thoroughly cleaned and freed from contaminants like dust, rust and residue of welding operations by flushing. It should also dry and be free from moisture before the oil is used.
