Castrol Perfecto HT 2 (ex BP Transcal LT)
Operating temp: -30°C to 250°C
Castrol Perfecto HT 2 (formerly known as BP 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.
Perfecto HT 2 is recommended primarily for non-pressurised 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 part of the circuit. The maximum recommended bulk-fluid temperature for Perfecto HT 2 is 250°C and the fluid also operates effectively in cooling systems down to bulk temperatures of -30°C.
Before being commisioned, the system should be pressure-tested for leaks and then thoroughly flushed with Perfecto HT 2. Water should never be used. With the system flushed and drained, it should be filled with fresh Perfecto HT 2. 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 Perfecto HT 2 various precuations 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.
