WRY series synthetic heat transfer oil is prepared by using alkyl synthetic hydrocarbon as raw material, and it is prepared by adding special compound of heat transfer oil with excellent performance. It has the following important characteristics:
Good oxidative stability and thermal stability-its oxidation resistance is 10 times higher than mineral oil, so compared with mineral oil, it is not easy to produce sludge due to oxidation. This feature is for users who do not use nitrogen to seal expansion tank Especially important
Good low temperature pumpability-can be transported by centrifugal pump even at low temperature of -25 ° C. Mineral oil will become jelly at this temperature. In fact, most mineral oils can no longer be transported by centrifugal pumps at -7 ° C. Therefore, systems using synthetic oils will be more convenient and quicker when cold start: Long life-small carbon deposit tendency, long life and significant energy saving effect.
