Oliterm 20 is a mineral heat transfer oil, paraffinic structure, and highly refined, whose additives provide it with great thermal stability and resistance to oxidation for use in indirect heating and cooling systems.
Properties and Advantages:
- Excellent thermal and oxidation stability, keeping circuits free of deposits and avoiding increase in viscosity, thus guaranteeing the efficiency of the heat transfer process. Long lifetime of the fluid in service, which allows a reduction in costs caused by maintenance shutdowns and downtime.
- High thermal conductivity, allowing faster heat dissipation.
- Its low vapour pressure guarantees resistance to cracking.
- High specific heat.
- Good fluidity at low temperatures, facilitating start‐up.
- Non‐corrosive..

Applications:
- Oliterm 20 is entender for closed‐circuit heat transmission systems.
Application temperature range (temperature of thermal boundary layer): from ‐10 ºC to +320 ºC
* In order to achieve maximum application temperatures, it is essential to keep the circuit completely closed, avoiding the presence of oxygen and/or humidity at all times.
- Oliterm 20 is intended for open‐circuit heat transmission systems.
Application temperature range (temperature of thermal boundary layer): from ‐10 ºC to +100 ºC.
