Liquid Coating Line for the New Factory in Saue

Project Challenge

The client's increased production volumes required a fully equipped painting line for a new factory. The line had to fit within a given space and include several large-scale booths, a powerful conveyor and a separate paint storage room.

The initial specification called for:

• Two paint booths with dimensions of 10×6 m
• A washing booth with dimensions of 10×6 m
• A motorised monorail conveyor with a total load capacity of 16,000 kg
• A paint storage room for painting equipment and daily-use paints

How We Built the Solution

We designed a compact and complete painting line to fit within the given space in the new production building. The solution included both painting and washing booths, a conveyor, as well as a paint storage room and equipment room.

Key components of the solution:

• Two water-heated paint booths with heat exchangers, with air exchange of 10,000 m³/h per booth
• A washing booth with a Husqvarna pressure washer
• A motorised monorail conveyor with two operator control panels (controllable directly from the paint chamber)
• Flap doors at the ends of the paint room
• An equipment room and 7 paint storage rooms with a separate solvent sensor
• An electronic mixing dosator for 2K multi-component substances
• Two GRACO electrostatic spray guns powered by air turbines
• 24 ATEX zone 1 luminaires with sturdy housings and clear glass

Automation

The line was equipped with solvent sensors and control automation specifically designed for paint rooms. The operator can control the conveyor with two operator control panels, including directly from the paint chamber, which makes the workflow flexible and safe.

Result

The client received a complete and automated liquid painting line for the new factory, meeting its increased production needs. The solution combined two large paint booths, a washing booth and a conveyor with a 16,000 kg load capacity into a seamless production line.
