Powder Coating Ovens:
Combination Infrared / Convection

Powder coating ovens that are classified as "Combination" infrared and convection heating methods, use both. They are “the best of both worlds” for many applications, particularly for powder coaters and facilities that process a variable mix of parts. 

In a combination oven, the infrared portion of the oven provides preheating, ahead of convection.  Infrared offers the advantage of ramping up quickly to the set temperature.  The convection module can then get to work without a time-consuming ramp-up.  When used for curing powders, infrared energy also prevents the powder from being disturbed before it is cured.  And, it helps prevent cross-contamination in facilities that use more than one color of powder.

The use of infrared ahead of convection cure also reduces total energy use. Convection uses high volumes of circulating hot air, which heat-soaks the part inside and out. This is not necessary for a good paint finish.  Infrared energy heats just the coating and the product surface, to the temperature level where convection is effective.  This reduces both cycle time and utility costs. 

Infrared also has the unique advantage of having the same absorption characteristics as most coatings, so most of the energy is used productively.

In our 50+ years of engineering and manufacturing powder coating ovens, we have found that a combination infrared and convection oven is an excellent solution for a wide range of tasks:

  • parts that are flat, or have intricate shapes
  • small and large parts
  • parts that are metal, plastic, MDF and glass
  • heavy work, and work that is light in weight
  • . . . and virtually any part thickness. 
Combination powder coating ovens are truly industry’s workhorse.
They are well-suited to a business climate where energy costs are high and  volatile. And because catalytic infrared heaters produce only CO2 and water as by-products, they are the most environmentally friendly powder coating ovens available.
