BP Transcal LT - Low temperature heat transfer oil

 

Description
Transcal LT is a high quality mineral oil combining low vapour pressure, and high levels of thermal stability, specific
heat and thermal conductivity with exceptional low temperature fluidity.

 

Applications
Transcal LT is recommended primarily for non pressurized closed liquid-phase heating systems that incorporate both heating and cooling branches (as, for example, where an exothermic or heat releasing reaction takes place).
The low temperature fluidity ensures that adequate circulation occurs in the coolest parts of the circuit.
The maximum recommended bulk-fluid temperature for Transcal LT is 250 °C, and the fluid also operates effectively in cooling systems down to bulk temperatures of -30 °C.
Before being commissioned, the system should be pressure tested for leaks and then thoroughly flushed with Transcal LT.
Water should never be used.
With the system flushed and drained, it should be filled with fresh Transcal LT. All air must be completely vented from the system before full temperature is imposed. For maximum efficiency, the heat transfer fluid should be circulated in conditions of turbulent flow. Care must be taken to ensure that bulk fluid temperature does not exceed 250 °C, as this could lead to degradation of the oil. Despite the excellent oxidation stability of Transcal LT various precautions must be taken to minimize exposure to air, especially if the temperature of the fluid in the expansion chamber exceeds 50 °C. A floating cover can be provided, or the oil can be blanketed with inert gas.

 

Main Benefits

  • Excellent heat transfer properties, which can be maintained over long periods of time.
  • Suitability for systems incorporating both heating and cooling branches.
