Based on a method proven over more than 30 years, the heat bundles, the centerpiece of the evaporator, have been produced at the GIG Karasek workshops in Austria for 15 years. The heat bundles are delivered ready to install and can be lifted directly from the truck into the opened evaporator. This and the special skills and routine of our disassembly and assembly fitters make it possible to reduce downtimes to an absolute minimum. Our customers highly appreciate the cooperation, the excellent know-how, the flexibility and the strong commitment of our company.

The GIG Karasek heat bundle manufacturing method offers the following advantages:

• The welding points for special plate shaping are resistance welded. As compared to laser-welded plates, in the area of the spot welds the surface remains smooth and clean.
• The welding is carried out directly along the outer edge of circumference.
• To avoid deformation of the heat-affected zone of the spot welds, each single spot weld is held in place by a special fixture when the heat bundles are being shaped.
