Deniz,

Please clarify where the operation (heat shrinking) will be done 
(Germany?, other countries?,  remote locations?,) and in how many 
locations.

If you need ONE unit in an equiped facility, that is very different from 
needing a dozen units that are dispursed in small workshops.

There are solutions for either situation.
