The heat transfer technology of thermal fluid heater has many advantages such as high temperature with low pressure, uniform heat transfer, precise temperature control, high efficiency and energy-saving, etc. It is more and more widely used in textile printing and dyeing, petrochemical, chemical fiber, paper, leather, food, building materials, metallurgy and other manufacturing industries.Therefore, the models and parameters of the thermal fluid heaters are very large, then how should we select the model of thermal fluid heater:

　　In general, a more scientific method to select the model of thermal fluid heater, which is to judge the model based on the equipment’s demand of the heat. There is a certain formula on heat calculation of thermal fluid heater, as follows: KCAL=0.65*Q*850*(T1-T2),(Remark: 0.65: heat required for unit thermal fluid heater to increase 1 degree(Kcal) ), Q: the amount of circulated medium, 850: specific gravity of the medium, T1: temperature of outlet oil, T2: temperature of inlet oil. With this formula we can calculate the heat required for the thermal fluid heater, then we can convert it to appropriate model.

　　If the user wants to use thermal fluid heater replace the steam boiler, it will be better to solve. There is a certain conversion relationship between the thermal fluid heater and steam boiler, 700KW=1T/H. The steam capacity of former boiler can be directly converted to the thermal power of the thermal fluid heater.

　　Besides, the selection of thermal fluid heater should also consider the following factors:

　　1, The user should be clear about the usage of thermal fluid heater, because different models are selected under different conditions. Once the selection is improper, it will not only waste resources but also have poor heat transfer.

　　2, We need to check the manufacturing qualifications of the company, confirm whether it has the ability to manufacture the kind of heater, whether equipped with complete product instruction, and also to investigate the after-sales service of the manufacturer, because some model is very special, some components are also available only in the original manufacturing unit.

　　3, Users shall conduct relevant investigations on the actual situation of their own units, such as venues, the measurement of their own demand, etc.

　　4, We need to compare the cost performance of thermal fluid heater at the same level, but also need to take into account the company’s relevant terms of service. In fact, to some extent, service is more important than price.

　　5, The time of boiling oil after hydrostatic pressure of thermal fluid heater is also should be taken into account, the length of time directly affects the operating cost, the time of some up to 12 days, some only 2 days, the saving cost of latter is more 60000yuan than former’s.
