Konark 820S

8 zone Lead Free Reflow oven

Konark 820S

Konark 820 is the new 8 zone Lead Free Reflow oven from EMS Technologies, Pune India. 

After successfully launching Konark 257 the 7 zone reflow and Konark 145 the 5 zone reflow with many machines working in the field (India as well as outside), this 8 zone is launched with two cooling zones as well. The reflow comes with same quality and reliability in terms of Mechanical as well as Electrical/Electronic parts, which is now proven in the field. 
EMS Technologies has now emerged as a leading Indian suplier of all SMT machines including Stencil Printers, Wave Soldering Machines and also low cost entry level Pick and Place machine. 

We need to change this to features title to Features list since application range will be pretty much same across product line - AR
