Case Study for Powder Coating System requiring environmental compliance
Ithica, NY – A manufacturer of steel bed frames was planning a generational transition that included moving to the Finger Lakes Region of New York. The challenge was compliance with the environmental regulations in such a pristine area.
HERR Industrial, Inc., was responsible for the design, manufacture, and installation of a powder coating system. The process scope included: loading parts on an overhead conveyor, pretreatment in a two-stage spray washer, drying in a convection dry-off oven, coating in a powder booth and then curing in a convection cure oven, and cooling before being manually unloaded.
Compliance with the environmental regulations was met using heat recovery to evaporate the overflow from the washer. A PAC column heat exchanger with stainless steel media used the heated oven exhaust and counter-flow of wastewater. The solution resulted in no discharge fines and energy savings.
The following equipment was incorporated into the design of the powder coating system. The line speed was 5 fpm and the part size was 2’wide x 6’high x 3’long.
- Enclosed Track Overhead Conveyor
- Two (2) Stage Spray Washer with water heating system
- Exhaust Heat Recovery wastewater discharge evaporator
- Combination Dry-off and Cure Oven, Convection forced air
- Environmental Room with air conditioning
- Installation of customer supplied powder booth
- Cooling Tunnel
