KLUBERTEMP 1-39 HT

As an operator of heat-carrier systems you have high expectations in terms of process reliability and safe operation. Hence, selecting the appropriate heat-transfer fluid is of utmost importance. Klübertherm 1-39 HT is an efficient heat-carrier fluid for closed systems, which meets the high requirements in terms of thermal stability.

Contrary to standard mineral oils, Klübertherm 1-39 HT contains highly refined hydrotreated heavy paraffinics to attain the high thermal stability of this heat-transfer fluid. Klübertherm 1-39 HT also stands out for its low vapour pressure and high oxidation stability. Therefore, Klübertherm 1-39 HT significantly contributes to reducing maintenance costs and extending oil change intervals.

Extended oil change intervals achievable due to highly refined paraffinic base oils
Reduced maintenance efforts and dependable operation due to high thermal stability
Low residue formation due to the high thermal and oxidation stability

Klübertherm 1-39 HT is exclusively recommended as a closed-loop heat-transfer fluid.
Thanks to its performance characteristics Klübertherm 1-39 HT can be used in various industries such as wood, textiles, chemicals, automotive, asphalt, cement.
Klübertherm 1-39 HT can be applied in new systems without prior cleaning, except when required for reasons of product quality. Residues of varnishes, oils and others originating from the system installation are usually not enough to affect the fluid lifetime. We strongly encourage you to take an oil sample in order to conduct laboratory analysis. Please check with your Klüber representative to assist you. Klübertherm 1-39 HT is normally compatible with common heat-transfer fluids.
The start-up procedure or cleaning process should be done in compliance with the documentation of the manufacturer of the heat transfer system. In the presence of inert gas, the operating time of this fluid may be considerably extended. It is highly recommended to analyse the oil every 6 months to allow a reliable and efficient operation of your heat transfer system.
