About In-Line Spray System

The Froedge In-line spray system was developed for those that need to chemically surface-treat lumber. One of its primary uses is the replacement of chemical dip tanks. Our clean, efficient spray system can be integrated into existing lines, reducing labor, chemical expense, material handling, and safety compliance issues.

Froedge spray systems have even been installed by users not previously applying treatment, because this low-cost, low-hassle method improves profits by increasing value.

Eliminate your dip tank, and all the aggravation that comes with it!

Less capital expense

Eliminate an extra material handling step

Eliminate the cost of a forklift and driver

Reduce maintenance time and cost

Reduce chemical costs by as much as 66%

Extremely Versatile

Can be used in both hardwood and softwood systems

Two Feed Styles

Transverse, typically used in stacker or bin sorter lines

Linear, typically used in application such as exiting a planer or other material handling operation where boards are traveling down a belt

Apply treatments such as anti-stain, iron-fix, brightener, or anti-fungal products

It is in the chemical room that the process starts. It houses incoming water, the chemicals used for treating, and all the pumps, filters, mix tank, meters, and controls to deliver and recirculate the treatment back into the system. The chemical room comes two ways. It can be ordered as a stand-alone unit, fabricated in a 20’ shipping container, which includes all components mounted on a raised, grated floor to contain any accidental spills. Alternatively, the components can be installed inside an existing or express built room inside or attached to the building housing the spray box.

The spray box is fabricated from stainless steel to prevent corrosion. It has two large pneumatically powered “clam-shell” type upper doors to allow access to the sprayer manifolds and for maintenance. There is a smaller door near the drain/return line to allow for debris clean out.

There are four sprayer manifolds two upper and two lower, two at the entrance of the box, and two at the exit. All are equipped with 82 degree pressurized spray nozzles engineered for proper position to direct the spray for full coverage of any board passing through the system, including the edges and ends.

A section of stainless steel chain moves the boards through the spray chamber. Each chain race has a short section removed in the spray zone, allowing for 100% coverage of each board. Sloped drain pans on each end of each race catch drips to return the fluid back inside the spray chamber, while vinyl curtains and a negative pressure air system contain the spray and chemical orders inside the chamber. Excess spray and fluid in the chamber is collected and recirculated through a drain and a negative airflow mist eliminator.
