Powder Coating System requiring environmental compliance

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.

SYSTEM COMPONENTS

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
• Three (3) 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
