In spite of a diverse production program the copper/aluminium based heat exchanger forms the heart of our production. Technical equipment is adapted to this fact.

Important Capital Equipment:

• Fin press
  • 5 press machines
    • 2 x 12 line ,2 x 6 line, 1 x 1 line
  • special jigs for fin press (mainly for coolers of power semiconductors, partly also the radiator program)

• Expanders
  • 3 versions of expanding
  • 3 x hydraulic - so called ball expander
  • 2 x bar (mechanic ) expander  with 2 tubes
  • 1 x horizontal expander with more tubes
• tube-cutters
• production of nipples
• NC cutting machine for sheets 
• NC edging press
• NC sheet bender
• Universal automatic programmable drill
• Standard tool machines (millers, lathes, drills, saws etc.)
• Other special machines and jigs

• Pressure testing– individual under water test (100 % of production )
  • heaters and coolers, dry air 10 – 31 bar
  • evaporators, condenser, nitrogen 25 – 31 bar (filled a low pressure nitrogen)

• Surface treatment
  • Steel headers and spot welds are treated with a protective paint (use of other surface treatments such as electrophoresis, powder coating, etc. are not available)
