The Pretreatment Washer's Containment Unit
• The Containment Unit is a steel drain platform with a fiberglass covering the entire top surface area. A stainless steel 40-mesh screen captures large particles and dirt.
• The waterproof Over-spray Curtains are attached to the containment unit on two or more sides to contain all solutions.
• The Drainage system, an integral part of the containment unit, includes a connection to the drain hoses for transfer of all process solutions to the Processing Unit.
The Pretreatment Washer's Processing Unit
• The Process Unit base provides a structure for the process equipment and serves as an over-spill reservoir with a drain for further processing or disposal.
• The Process Unit sump pumps transfer the process solutions from the containment unit into the filter system.
• The Multi-stage Filter System provides 50-, 10- and 5-micron disposable filters.
• A Low-Volume/High-Pressure Pump (2 gpm/up to 1500 psi) is used with a Stainless Steel Spray Wand to remove all soils and contaminants from the metal substrate and features a cleaning-chemical-solution injector port for greater cleaning flexibility.
• Pneumatic Valves control the flow of solutions throughout the system during the wash, rinse and pretreatment processes.
• A Pretreatment-Solution Transfer Pump is used to transfer pretreatment chemicals up to 60 psi to the Pretreatment Spray Wand.
• The transfer pump also recirculates the solution in the heated pretreatment-solution container to maintain consistent temperature.
• Recycling and containment of all phosphates or pretreatment chemicals reduces cost and supports environmental initiatives.
• Pretreatment chemical solution control is maintained by manual standard titration methods.

Controls
• NEMA 12-rated control panel containing relays, contactors, rotary control switch, timer, and temperature control switches.
• UL listed 220/1/60 Control Panel
