Polypropylene Washers—Pretreatment That Saves Energy & Stops Corrosion
Polypropylene Washers: The washer that will save you money and decrease downtime during production.
Since 1989 GAT has set the standard for industrial polypropylene washers that outlast steel and composite housings while slashing utility costs. Whether you need a mesh‑belt, drum‑style barrel or batch washer, every PolyPro™ washer delivers rust‑proof durability, lower operating temps and crystal‑clear visibility inside the spray zone.
Why Choose a PolyPro™ Industrial Parts Washer?
| Advantage | How Polypropylene Delivers | Bottom-Line Benefit |
|---|---|---|
| Energy-Efficient Housing | Plastic’s low heat transfer means tanks hold temperature longer | Up to 40 % gas savings & cooler shop floor |
| Translucent Panels | Natural light illuminates spray patterns | Faster nozzle checks & safer work zone |
| In-Tank Plate Heat Exchanger | 2× the surface area of tube coils | 35–40 % lower BTU input & longer burner life |
| Modular Design | Bolt-on stages grow with demand | Scale from 3-stage to 7-stage without new housing |
| 10-Year No-Rust Warranty | Polypropylene won’t blister, swell or corrode | Lowest total cost of ownership in the industry |
The GAT Difference
PolyPro washers have a lower coefficient of heat transfer than steel and composite washer and as a result are more energy-efficient.
Our washers offer a translucent material in polypropylene resulting in a safer and brighter environment.
Using twice the surface area of a tube-style heat exchanger we decrease energy usage by 35-40% compared to all other washer manufacturers.
Easily expand to fit your manufacturing needs.
Our 10-year warranty covers any incident of rust and corrosion on any of our washer housings, no matter their use or purpose.
Features & Benefits
- More energy-efficient: Polypropylene washers have a lower coefficient of heat transfer than steel and composite washer.
- Polypropylene will not blister, swell, crack or delaminate, like hygroscopic composite materials tend to do over time such as steel or composites.
- PolyPro washers feature a better see-through material in polypropylene.
- Industry-leading 10-year warranty on all PolyPro Washers
- Modular
- Twice surface area of tube-style heat exchanger
- Quieter operations
- Lower firing rate of your burner, which puts less wear and tear on your gas train components and heat exchanger while lowering your carbon footprint. Studies show PolyPro washers reduce energy use up to 40% over steel housed washers. It also means a safer working environment with a lower temperature around the washer and fully illuminated inside the washer.
- Lower maintenance costs.
- No more guesswork about spray patterns or which nozzles may need your attention. This means less downtime during production with a safer working environment and more money in your pocket.
- Our 10-year warranty covers any incident of rust and corrosion on any of our washer housings, no matter their use or purpose.
- Easily expand to fit your manufacturing needs.
- 35-40% decrease in energy usage compared to all other washer manufacturers.
- Less stressful work environment for all personnel.
Three Polypropylene Washer Configurations
Our GAT belt washers are designed to accommodate a wide range of material handling processes. The washer housing features our industry-leading polypropylene construction with a stainless steel, structure and schedule 80 PVC piping. Each of our mesh belt washers includes drives, sprockets, take-up, and motors to help the belt washer get the job done.
- Continuous‑flow lines with racked or hung parts
- Stainless frame, Schedule 80 PVC piping, variable‑speed belt widths 12–60 in.
Do you need to do a little tumbling and mechanical pretreatment of your parts before taking a dip in the aqueous chemical process? Our GAT barrel washers are the perfect solution for high volumes of parts not designed for multipart or ‘Christmas tree’ racking. Our GAT barrel washers feature a full-length support mast to guarantee your system nozzles’ placement and alignment are doing their job. The auger flight designed barrel is perforated and highly resistant to corrosion and abrasion. The barrel includes multiple support points to eliminate sag, maintaining constant part movement.
- High‑volume bulk parts needing tumble action
- Perforated auger flight barrel, full‑length nozzle mast, abrasion‑resistant lining
Do you need an entry-level industrial finishing solution? Start with our GAT batch washers. They’re built with the same structure and material of our GAT automatic spray washers. This means the batch washer housing is made from our patented polypropylene and stainless steel design and construction. Our GAT batch washers are great for powder coating or wet painting finishing lines and can come with or without separate spray and systems.
- Entry‑level or low‑volume finishing cells
- Same PolyPro housing as auto lines, optional manual or auto spray cycles
