Castrol Perfecto HT 5 (red) (previous product name BP Transcal N (red)) is a re
low vapor pressure, high thermal stability and high specific heat and good
Thermal conductivity of selected mineral oil-based heat transfer media. About leaks in the system
the product is colored red to make it easier to find.
use
Castrol Perfecto HT 5 (red) is used for pressureless, indirect heating of
Heat transfer systems, e.g. B. in the food, construction, plastics, wood and metal industries
as well as in laundries and on ships.
Instructions for use
Heat carriers expand when heated. As compensation must in das
An expansion tank must be installed in the heat transfer system. Before filling the system must
a pressure test for leaks must be carried out (do not use water). Then should
flushed the system with Castrol Perfecto HT 5 (red) and after emptying with new Castrol Perfecto
HT 5 (red) can be filled. When filling, ensure that the system is well vented. the
The filling process is complete when the oil level in the expansion tank is 30% to 45% of the
operating temperature has reached the expected oil level. When the system is commissioned
to heat up slowly. At +100 °C to +120 °C, the temperature should be kept constant for a long time
so that any moisture that may be present can evaporate.
The expansion tank is the only place where the heat transfer medium comes into contact with air
can come. Although Castrol Perfecto HT 5 (red) has excellent oxidation stability,
the oil temperature in the expansion tank should not exceed +50 °C. A cover with
Floating bodies (e.g. plastic balls) reduces the oil/air contact surface. At +50 °C
If temperatures exceed this, an inert gas cover (e.g. nitrogen) must be provided.
Notes: The characteristic values ​​given in the table below are flash point and ignition temperature
are not directly related to the permissible operating temperature of the heat transfer medium.
It is only characteristic property data. Virtually all heat transfer systems
are operated at temperatures above these characteristic values.
The following must be observed when constructing and operating heat transfer systems:
DIN 4754 "Heat transfer systems with organic liquids - safety-related
requirements, test"
VDI 3033 "Heat transfer systems with heat carriers other than water - structure, operation and
Maintenance"
Operating temperature range: -10 °C to +340 °C (film temperature). are higher temperatures
necessary, synthetic heat carriers are available in the Castrol program.
