Another is the poor quality base oil or synthetic heat transfer is not good enough, and even some manufacturers use non-standard oil as the base oil. Some manufacturers blind pursuit of low-cost thermal oil production to seize the market, which also caters to some users only ask price regardless of the quality of the mind, such as carbon residue increase HTF is quite fast synthetic heat transfer oil, the use of time is not long HTF coefficient will be significantly reduced, will cause local congestion, and even whole thickens, early retirement, increasing cleaning costs, downtime and operating costs. Often hear oil boiler plant commissioning say: some HTF too much moisture, for a long time could not finish off the water temperature synthetic heat transfer, poor quality of this HTF. In fact, this statement is wholly wrong, oil moisture content is generally at 500 g / ton. If the system according to the amount of water to dehydrated professional HTF, a few hours to finish off the water, but many systems in 0.5-5% moisture content, so a lot of water is generally in the boiler or heating equipment production process After the water pressure test and residual water. But it also is not terrible, as long as the correct way to operate dehydration, and soon will put the water off the stem, combined with many users dehydration unskilled, resulting in a few days or ten days in the water system is not able to take off dry, end-users will come to a conclusion: The HTF heavy water, poor quality.
