The circulation type electric heater heats up the fluid in the forced convection mode.That is,the fluid is pumped into the heating chamber at one end of the heater,where it is heated,and flows out of the heater at the other end. That is a heating mode by forced.

Characteristics:

1. Compact size,big power,Circulation heater has immersion heater inside,Max power can be 1 MW.
2. Fast heating, high precision of tempt control and high thermal efficiency.
3. Wide range of application, high adaptability. Circulation type heater can be used either in normal situation or in anti explosive situation. Its protection of explosion grade can reach B or C and its pressure endurance reaches 20 MPa .
4. High heating temperature:circulation type heater is designed to have max empt of 650℃ .
5. Fully automatic control:by means of control system designing for the circulation heater it is easy to effect auto control of parameters like outlet tempt,pressure,and flow rate and connect it to computer network for man/machine conversation.
6. Long working life,high reliability: circulation heater is designed to have its power load correspond to different applications and has multiple-fold protection,so that safety and working life of the heater is greatly enhanced.

Typical applications area:

1. Various kinds of water heating includeing bathroom water heating civilian life and process water heating for industrial purposes.
2. The heating of hydrocarbon including heat conducting oil,fuel oil,tar,and paraffin.
3. Heating of cleaning machine and ice melting trough,including NaOH solution and all kinds of detergent.
4. Heating of air,suited to drying up certain powder,chemical engineering process and jet drying under certain pressure.
5. Heating of steam.
6. Heating of gases,including H2,N2 and various kinds of inert gases.

The Type signifies:

Note: The anti explosive type in XH heater series is "XHEx" and it is made of stainless steel or carbon steel.If heating tempt is the range of 100℃-200℃,a heat diffusion sector of 100 will have to be added between flange and terminal connection box,whose dimension shall be A+ 100.If heating tempt is higher the heat diffusion sector will have to be longer.Insulation material and thickness will depend on the user's media tempt and user requirement. For specifics of the design please consult our technical dept.

Select the type according to our product handbook.Naturally,the selection of circulation heater specifications is not the only one.To select heater according to nominal power and power density,you may selec one with bigger flange and smaller length,or smaller flange with bigger length.Selection will have to depend on the actuality of user's situation.In any case you may be sure of the assistance from our tech dept.
