Closed system with nitrogen, the need for additional sources of nitrogen or a nitrogen generating system, so complicated and Oil System equipment to operate, maintain, have brought a certain amount of influence to improve the system's complexity, increased investment in equipment and improve production operation, maintenance costs, easy to popularize and promote. At present, only large-scale domestic enterprises, large oil heating system and a nitrogen gas source enterprise adoption. For no nitrogen gas source and thermal oil system is not great and limited funds of the enterprise, the use of cold fluid sealing device make HTF isolated from the atmosphere, but also to effectively protect HTF prevent air oxidation and prolong life HTF. The above information is provided by Fengqiu County Taihang Chemical Co., Ltd, Chengde conducting oil, I hope will be helpful. In recent years, oil demand expanded significantly. Some enterprise users and applications of heat transfer equipment, to meet the needs of its heat exchanger technology, and some need to choose some kind of inorganic heat transfer medium (soft water-based), but more need to purchase a suitable organic heat transfer medium that is HTF. So, those who want to purchase the HTF, HTF first face of many businesses and the cold product physical data, in the end how to make a clear choice? Next, we will bring you professional knowledge to explain. First you need to heat when the temperature requirements of their own equipment, to properly assess the level of purchase HTF models, solar thermal oil, not further mentioned here. Then, oil sales, customer best able to understand some of the conventional physical and chemical properties related to conducting oil products, such as conducting oil quality performance best embodies several major physical and chemical indicators: viscosity, viscosity index, flash point, pour point and other indicators. Finally, we recommend that buyers consult HTF HTF applied directly to technical experts. HTF species, Fengqiu County Taihang Chemical (certified), Chengde conducting oil supplied by Fengqiu County Taihang Chemical Co., Ltd. Fengqiu County Taihang Chemical Co., Ltd (www.hndaoreyou.com) Henan Xinxiang, fuel oil leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Fengqiu County Taihang Chemical Co., Ltd. leadership with the staff warmly welcome all inquiries negotiations to create Fengqiu County Taihang Chemical Co., a better future.
