New powder coating facility

Every year HANSA Klimasysteme has to coat 10,000 square metres of metal / New system brings better flexibility and greater individuality

The investment carousel continues to turn at HANSA Klimasysteme GmbH. Since 2015, the manufacturer of ventilation and air conditioning systems has already built two halls and also purchased a new punching machine for 1.5 million euros. Now a further 415,000 euros have been invested in a new facility for powder coating of various components for air conditioning units.

 "I am delighted with this investment," said Managing Director Jan Neumann at the inauguration of the plant. "It will help the company move forward." The new system makes the company more flexible and saves the costs that were previously spent on powder coating at a service provider. Most of the parts installed in an air conditioning unit are made of metal and therefore have to be protected against corrosion. Depending on the application, different corrosion protection classes can be achieved. The highest corrosion protection class achieved by HANSA Klimasysteme is C5-M in accordance with DIN EN ISO 12944, which is used in cases of very high corrosiveness, e.g. in coastal or offshore areas.

In powder coating, the components are provided with an extremely thin layer of powder, thus preventing contact of the surface with corrosion-promoting substances. For this purpose, the components are first cleaned and dried, then the powder is applied. This is applied by hand because the parts are too different for automation. Finally, the powder adhering to the surface is baked in an oven.

For HANSA, the advantages of having its own powder coating plant are obvious: "In recent years, the demand for built-in parts with increased corrosion protection has risen continuously at HANSA," explains Technical Director Dr. Matthias Lamping. This means that the plant pays for itself in a short time. Added to this, according to Lamping, is the time saving. Until now, the parts to be coated had to be collected, taken to the service provider and waited for the delivery of the processed parts. This is now no longer necessary. "And if a part is missing or defective, we can now not only produce it ourselves, but also quickly insert it during the coating process," says the managing director. "This makes us much more flexible." With a floor space of 300 square meters, the new plant consisting of three chambers is "rather small, but absolutely sufficient for our own needs" according to production manager Bunger. The company has created two new permanent jobs for the ongoing operation.
