Heat Transfer Oil
Greyhound Heat Transfer oils are formulated with high-quality base oils to ensure excellent heat transfer and long-term protection of the circuits against corrosion and deterioration. In many industrial applications, heating is provided indirectly by circulating hot oil through a heat exchanger, thus reducing hot spots and increasing the safety of the heating process. In quenching applications, heat is required to be rapidly drawn away from the parts in contact with the oil. Due to the extremely high temperatures experienced in these applications, the oil must provide excellent thermal stability to resist oxidation, while also providing good heat transfer characteristics and resistance to carbon deposits.
Application: Filling of heat transfer units
Greyhound™ Heat Transfer ISO 32 is a mineral oil-based heat transfer oil having a high viscosity index and narrow boiling point range. The allowed maximum film temperature at the heat transfer surface is 320°C, and in the system it is 300°C.
The service life of the heat transfer medium depends greatly on the design of the heat transfer system and the operating conditions. The service life could be up to 5 years if the system is designed properly, and when it is protected from extreme load conditions. The service life could be extended significantly if low pressure (1.2-1.5 bar gauge pressure) and inert gas atmosphere (nitrogen) are used in an expansion tank. For safety and economic reasons, it is recommended to check the condition of the oil regularly, but once a year at least. Handling HT 32 is safer than when handling most other synthetic oils, as it is not toxic and has a low vapour pressure. It can be collected as used oil after its application, for recycling or disposal.
Our products are manufactured in Europe at ISO-certified plants and meet the highest international standards.
