Gas Catalytic Infrared Applications

 Gas catalytic IR has many industrial heating applications. At Heraeus Noblelight, our team of engineers can help you find the correct solution to meet your requirements.

The use of Intelligent Infrared heating will always give you a competitive advantage as you can see also in our  case studies with gas catalytic IR!

Gas Catalytic IR for Liquid Finishing

Vulcan Catalytic® Gas Catalytic High Efficiency Ovens For Liquid Finishing

Infrared for Liquid Finishing

Gas Catalytic IR is easily absorbed by both aqueous and solvent based liquid finishes.

The use of Gas Catalytic IR in liquid curing processes offer the same advantages as in other curing processes such as E Coating and powder coating:

  • The 3:1 principle applies. This means that for every 3 minutes a curing process would take in a convection oven, a Gas Catalytic IR oven would only take 1 minute.
  • Gas Catalytic IR ovens are 50% the size of a convection oven.
  • Gas Catalytic IR Ovens use up to 50% less energy than a convection oven.

Gas Catalytic Infrared Ovens from Vulcan Catalytic® Systems are modular in design, pre-wired and plumbed ready for use within one or two days of on site delivery. Yet, they are custom tailored to the customer’s specific requirements of part size, type of coating, conveyor height and line speed. Our catalytic heaters can be used in hazardous locations and have Factory Mutual and CSA approvals.

How We Can Help You

The engineers at Vulcan Catalytic® Systems design catalytic heating systems for heating processes that require a part temperature of up to 650°F/345°C. Whether it is for plastics, powder or liquid coating, web drying, or preheating, the systems are carefully tested in our state of the art facility, ensuring complete satisfaction before shipping the system.

We Supply:

  • Fully built modular ovens, designed, manufactured and installed by us
  • We can supply heater and control packages
  • Heaters only
  • Full package of heaters, controls and gas management assemblies.
  • Complete Ovens shipped in modular sections – pre-wired and plumbed.
  • We also work with turn key system integrators who supply complete powder coating lines

Gas Catalytic IR for Powder Coating

Gelling and Curing of Powder Coating by Gas Catalytic Infrared Heat

Infrared for powder coating

Generally, powder absorbs infrared radiation very well, heats up very quickly and is gelled in significantly shorter time than in a conventional convection oven. As there is no circulation of air, dust inclusion is eliminated and the powder is not swirled around. A fast melt improves the coating quality and increases the production line speed. Infrared heat is transferred faster and at higher power than hot air, so that in most cases the oven is shorter than a convection oven or the production line speed is faster.

As well as a seamless coating, powder coating also provides excellent mechanical and chemical properties. The precisely accurate process and the curing of the powder is ensured by the flexibility of Heraeus Noblelight gas catalytic ovens.

Liquid or Powder Finish?

The move from liquid to powder is well established. The advantages of powder over liquid can be summarized as follows:

  • A powder coated finish is significantly tougher than a liquid finish.
  • Over spray losses for liquid finishes can be as much as 75%.
  • Around 80% of liquid finishes used in the USA are solvent based and present environmental issues.
  • Even aqueous based finishes still contain some solvents contained within the resin structure
  • The storage and transportation of liquid finishes requires the use of IBC’s (Intermediate Bulk Containers). These require special handling and storage techniques.
  • Overall, powder finishes represent a more cost effective way to getting a better finish.

Gas Catalytic IR for Non-Conductive Substrates

Gas Catalytic IR for Non-Conductive Substrates

Infrared cures MDF

The curing of coatings on non-conductive substrates requires special drying equipment. The parts themselves can be flat MDF boards but also three-dimensional plastic products. The oven must safely cure the paint on the work pieces without causing heat damage to the product itself. Decisive is the response time, infrared emitters respond quickly to control commands and can be controlled individually.

Gas catalytic IR ovens can be equipped with a zone control that allows adjustment of every temperature profile according to the requirements of sensitive product. Our application specialists can establish with You the required oven settings. Various programs to meet the different requirements can be incorporated in the control system and these can be called up on demand.
