Large diesel engines meet VOC coating requirements

MTU Friedrichshafen, located in Germany, manufactures diesel engines and complete propulsion systems for ships, heavy-duty land and rail vehicles, industrial applications and decentralised power plants.

The most modern and technically innovative engine of its class has a performance of 9.000 kW! These engines have to be coated with a wide variety of materials. Two-component solvents and Two-component waterborne PUR and epoxy materials are used in many colours, depending on the request of the customers.

Since 2007, MTU has been using Graco two-component ProMix Easy and ProMix II equipment. Thanks to this, MTU employees gained a lot of experience with handling two-component materials and their application with 2K dosing units. Before 2007, a circulation line and pressure pot were used.
 

Expanding the paint room

After several years, two new Graco ProMix 2KE units were installed and put into service. Every 2K unit is equipped with two spray guns and gun flush boxes. Thanks to this configuration, a much faster colour change is possible with reduced use of flushing solvents. The local Graco distributor, MK Stadelmaier GmbH, was able to achieve an optimal result by optimising this configuration for MTU.

Significantly reduced VOC rate

Through the use of 2K waterborne materials and Graco 2K technology, the VOC rate significantly reduced. The user-friendly operation and precise control of the mix ratio and the pot-life, guarantee high security during the painting process. Simultaneous improvements in quality, paint and flushing solvent savings, as well as the minimisation of the set-up time, completed the success of the system in the paint shop.
