Easy Black Electrical Control Panel
Electrical Control Panel, shown closed and open, which is used to maintain the proper operating temperature of each electrically or gas heated processing compartments. The unit has red flashing alarm light set to activate 2 degrees above set operating temperature. Additional safety features include automatic shut-down of electric heaters in the overheating processing station if operating temperature exceeds 3 degrees above set operating temperature.
Easy Black Exhaust Hood
Large inline exhaust blower to remove water vapor and steam from heated processing compartments. Exhaust pipe at top of blower must be run to the outside of the building. Smaller Easy Black system with tanks 16"x16"x20" using a 12" dia. pipe, larger Easy Black system with 16"x38"x20" processing compartments requires a 16" dia. exhaust pipe.
Easy Black gas burners
This picture shows the underneath gas burner system with electric gas solenoid valve, Baso gas pilot safety unit. The upper left corner of the photo shows the exhaust flue and next to it is the automatic water solenoid valve system to replenish water that has left the black oxide tank as steam. This will ensure that no red work will be produced while using Du-Lite's Easy Black Plus System.
Easy Black water valves
Photo of two Water Solenoid Valves which automatically replenishes water that has left the processing tank as steam. This is very important because the water that is lost as steam from the processing tank is not replenished immediately the black oxide tank will overheat and produce red work which is unacceptable. These valves are electrically controlled by the temperature indicating controller located in the main control panel.
Easy Black Metal Finishing Installation
In September of 2012, our technicians installed a large custom built metal finishing system in a large military base in the eastern United States.

The Du-Lite Easy Black Plus Systems are Custom Built to Order

  • A complete turnkey black oxide system.
  • Safety and accuracy. Automatic temperature controls of all heated processing tanks. Each electrically heated compartment is protected by a high-temperature red flashing alarm light set to activate 2 degrees above set operating temperature and is located on the control panel. If the #45 Cleaner or the black oxide tank continues to over-heat by 3 degrees higher the electricity to the heaters will automatically shut off to that tank.
  • The ability to blacken parts in your own plant, eliminating outside vendor delays and lost parts
  • No gas burners with open flames or flues to contend with.
  • All electricity-heated compartments are insulated with 1″ fiberglass boards so that smaller wattage heaters can be used for faster heat up time at less cost.
  • Black oxide processing tanks equipped with an automatic water feed system to replenish water that has left the processing tanks as steam or drag out eliminating red work.
  • All stainless steel construction inside and out. Steel rinse tanks are prone to rusting, forming rust particles which can be deposited on your finished work.
  • The system can be adapted to run other in-house processes, i.e. stainless steel passivating, parts cleaning, aluminum chromating, zinc, iron, manganese phosphating, acid bright dipping or rust removal and oiling processes.
  • Manual or automatic waste treatment system available for pH adjustment of rinse water.
  • Larger custom size units available.
  • Factory laboratory and technical assistance available.
  • Systems can pay for themselves in 6 to 12 months.
