LUBECHEM TECHNO VDL

High Performance Heath Transfer Oil
Quality lubricant for reliable heat transfer systems

Lubechem Techno HT is formulated with carefully selected, high quality solvent refined, medium to high viscosity index mineral oils to provide the highest level of protection & performance in indirect closed fluid heat transfer systems operating at temperatures up to 320°C.

Services Life

The life of Lubechem Techno HT depends on the design and usage of the system. If the system is well designed, and not subjected to abnormal workloads the oil life can be many years.

ISO 6743-3: 2003 DAA Normal Duty

Application

- Recommended for heat transfer used in all closed circuit heat exchangers and other circulation equipments, operating at bulk temperatures up to 320°C.

- Can also be used in hot or cold quenching system.

Imporant to note

Before starting new unit or restarting after maintenance or in the presence of residual moisture in the oil at normal operating temperature, the temperature of the unit should be reduced to around 100°C to blow-off all the steam before returning to the normal operating temperature.
