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.


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
