SPY3 series mobile induction heating machine，with cable 3～5m long and power 5～100KW，frequency 150KHZ around，can be used to braze copper tube connectors and copper bars of transformer, or to heat the metal surface for coating , or to heat the deck surface for paint removing , etc. Because of the difference of materials, difference of heating desires and difference of coil shapes and sizes, SPY3 machines must be customized to match different usage.
      Now, Shuangping has developed complete series of SPY3 machines for copper tube brazing usage.  These machines may not fit other heating applications. So when ordering, following message should be given to us for good matching:
（1） Material and dimension of the work piece to be heated,
（2） Heating application and speed, heating time required;

 

Model	Max Oscillate power KVA	Description	Input voltage	Max Current Of coil	Copper Tube Size To braze
SPY3-05	5KVA	Only heating machine	Single phase 220V	450A
SPY3-05W		With pump and water bottle for repair only
SPY3-05T		With pump and water tank for general use
SPY3-10	10KVA	Only heating machine	三相 380V	800A
SPY3-10-C1-PLC		With 1P cooler, PLC control and touching screen panel
SPY3-18	18KVA	Only heating machine		1100A
SPY3-18-C2-PLC		With 1P cooler, PLC control and touching screen panel
SPY3-30	30KVA	Only heating machine		1400A
SPY3-30-C2-PLC		With 1P cooler, PLC control and touching screen panel

       Except the SPY3 machine for copper tube brazing, Shuangping can customize all series SPY3 mobile induction heating machines of 5-160KW for various kind of heating applications.
 
 （1）With cooler and PLC control 

      Inner cooler, PLC control and touch screen operating panel, make SPY3-C-PLC mobile induction heating machines easy to install and operate. Brazing parameters can be preset and recorded to simple operation and improve the brazing quality。There are mainly three models for ing，SPY3-10-C1-PLC，SPY3-18-C2-PLC and SPY3-30-C2-PLC for copper tube brazing usages of  refrige ration industry. 

（2） SPY3 heating machine only
     SPY3 single hating machine is simple to operate and cheap in price, common Shuangping front panel is used which is simple to operate.

SPY3 machines are the most recommended models of mobile induction heating machines.  These machines are widely used Due to its light and small heating head.
Main advantages and disadvantages:
（1） Small and light heating head.  For example, heating head of SPY3-10 is only 0.9KG, it is light enough for hand holding and it is also easy for multi-joint robot to take. 
（2） Heating head is reliable and not easy to damage.  There is only one or two caps inside the heating head cabinet, simple water cooled, so it is simple in structure and reliable in quality；
（3） High heating efficiency and saving energy. SPY3 machines is series and parallel oscillating circuit, only the oscillating cap and coil flows big current to heat, cable is of small current so as to decrease heat consumption and save energy. 
（4） SPY3 machines are usually designed for specific usage of same type material and similar inductance of coil,  this is the limit for that machine which should be taken in consideration when ordering.

Applications

    SPY3 machines adopt parallel oscillating circuit, inverting high frequency power is output through transformer to the heating head (oscillating cap), and then output to coil for heating.

     Due to the parallel oscillating structure, there is only capacitor inside heating head which leads to small, light and high reliability of the heating head.  Furthermore, large heating current is oscillated directly between capacitor and induction coil to make the heating efficiency much more high. 
    Now, In most of the mobile heating machines in market, series oscillating structure is used and heating head is a water-cooled transformer, same as our SPY series machine.  This type of machine is featured by low heating efficiency and easy damage of the heating head. In application, SPY3 machines can totally take place of them and give superior operation, high reliability and less damage. 

Compared with oxy-acetylene flame heating, SPY3 machines have a lot of advantages as below:
   (1)  Saving of energy, Low cost; 
   (2)  Easy operation, no need for professionals and special training.
   (3)  Good working surroundings and safe.
In SPY3 machines, our latest third generation inverting and adjust technologies are adopted to realize soft switching of the IGBT components and independent adjusting of the power and frequency, so as to reach a marvelous heating feature of the machine.
