Spray washing line

The spray washing line is a tunnel with spray stages that remove oil, dirt and rust from parts on the conveyor before coating, followed by a drying oven. The example line on the Turnkey powder coating plant page has two stages; stage count and chemistry follow the metal and the corrosion class. PLC control and a cardan chain conveyor are standard.

How we size it

Tunnel cross-section follows the part envelope; stage length follows the contact time the chemistry needs at the line speed; tank volume follows the spray flow and the drag-out. Drying oven length follows the time the part needs to dry at the line speed.

What it is for

  • Removal of oil, dirt and rust from metal surfaces
  • Surface preparation for coating adhesion
  • Tunnel cross-section for parts of different sizes

Options

  • Two to seven stages
  • Iron phosphate, zirconium or aluminium conversion
  • Stainless steel tanks and heat exchangers
  • Rinse-water recycling

Standards

Built to the Machinery Directive with CE Declaration of Conformity; chemistry per your supplier's process sheet.

Values marked "Per project" in the table are set from your part and line, and appear in the proposal.
