In addition to the expertise our team brings to each project, we offer after-sale support that is second to none. Our system solutions include:

Paint system engineering studies to increase product yield

Air balance analysis to reduce airhouse filter change-outs to lower operating costs

Energy study for paint shop optimization for short payback periods, such as existing abatement equipment

Design/Build services for new paint lines, paint line retrofits, and spray booth conversions from 100% fresh air to recirculating systems

Best in class sludge and water management systems for wet scrubber paint lines

Liquid Filtration Systems

Our self-cleaning liquid filtration systems are designed for pretreatment alkaline cleaner and phosphate stages. We offer standard and custom equipment selection that can save maintenance time by eliminating manual filter replacements. Our liquid filtration systems include:

Pretreatment Filtration

  • Pressure filters, filter presses, and vacuum filters for phosphate stage sludge removal
  • Hydrocyclone concentrators with automatic dewatering filter for phosphate sludge removal
  • Gravity media filters for cleaner stage filtration
  • Hydrocyclones for weld ball and dirt removal from cleaner stages
  • Oil separators for cleaner stages
  • Reverse Osmosis (RO) systems for rinse stages
