Gas Catalytic Ovens for Railway Industry – Drying Coaches in 8 Minutes

Gas Catalytic ovens is the ideal paint drying oven for drying coaches, locomotives and metro car body. Since most rail coaches are shaped flat with not too many bends and curves gas catalytic ovens are ideal. Conventionally rail coaches take 25-30 minutes of forced drying and consume lot of fuel due to large length of the rail coach. With the gas catalytic oven technology we use a special heat radiation transfer technique where the gas catalytic pads drys the paint and not the surface. This brings down the drying time between 6-8 minutes and it consumes only 50% less fuel. This oven also requires less maintenance.

Prism has supplied many gas catalytic ovens for rail coaches  in India as well as abroad.

 

Latest Railway Paint Shop Technology

Prism is considered the world leader in supplying complete railway and locomotive Paint shops around the world. We supply the complete set of systems required for painting which include paint booths, paint drying ovens, gas catalytic oven, Blast rooms, blasting, Painting robots and reciprocator arms, 3 and 2 axis platforms which are pneumatically operated, paint kitchens, air handling units and shower rain tester booths which are used to test for water leakage. We can also supply complete paint booth with heating systems where painting and drying takes place in the same chamber.

Prism also has introdued the MAGIC painter gun system which can save locomotive and railway coach manufacturers more than 50% paint and does not use compressed air. This will give paint and energy savings drastically. Prism also has supplied the gas catalytic oven which can dry the paint in 10 minutes compared to 30 minutes for drying the coach. This oven consumes only 50% energy and fuel compared to conventional ovens.

 

The Gun which saves 50% Paint for Aircraft Finishing and MRO

Yes you heard it. The magic painter gun can save you around 50% paint while painting aircraft. We all know that painting aircraft,helicopters and military aircraft is expensive. The finish required must be exceptional quality. Too much of paint or too little paint can have an impact of the performance of the aircraft. Hence the quality of refinishing is very important. Different aircraft require different amounts  of paint. The majority of aircraft are painted with a high HVLP system or a electrostatic gun system which is able to add a very thin, even layer of paint. Paint is generally applied in three layers: primer, base coast, top coat. It is the top coat that gives a plane its shiny appearance.

Prism has introduced a revolutionary painting gun known as the MAGIC PAINTER GUN SYSTEM for aircraft painting and MRO painting where the system does not use compressed air and the gun can sav you upto 50% paint. When compressed air is not used the issues associated with compressed air such as oil,moisture, humidity and high compressor maintenance required is eliminated. The finish achieved also is more superior in quality. Magic painter gun also uses warm dry air for painting which is ideal for the finest level of paint atomisation and elimination of moisture. Due to the warm dry air used, your paint drying is also accelerated to some extent. finish  achieved is very superior.

Highlights of the system include:

  • Paint savings upto 50%
  • Energy savings as it does not use compressed air
  • Transfer efficiency between 85-90%
  • Sprays paint at 4-7 PSI and 0.7 Bar
  • Temperature in air supplied by the gun is 45-60 degrees Celsius
  • Able to penetrate into grooves and crevices of the AIRCRAFT
  • Supplies warm dry air without any moisture and system does not use compressed air. Can be connected to your existing paint supply system. Better paint finish quality
  • No complex expensive electrostatic procedures and maintenance such as grounding or earthing
  • More paint savings leads to reduced VOCS
  • Warm dry air quickens drying time
  • Operator health safety is increased as there is no over spray
  • Cleaner greener environment

Magic painter system can be used on aircraft’s of any size, helicopters, military equipment aircraft’s, MRO painting hangars for refinishing etc.

Difference between Gas Catalytic Oven and Electric Infrared Oven

Gas catalytic oven uses radiation heat transfer technique  to heat only the paint and powder without heating the surface. Electric Infrared Oven  use electric infrared heaters to radiate heat into a part. The ovens can be designed in various shapes and for nearly any process involving heat treatment. Gas catalytic oven is the most cost effective and energy efficient curing solution. Compared to electric infrared, gas catalytic infrared uses significantly less energy to operate. These ovens are commonly used for curing powder coatings on nearly any substrate. Further life of the electric heaters are less which means higher replacement costs which will increase your maintenance costs. Gas catalytic infrared ovens do not rely on heated, moving air to increase the part temperature.  This reduces opportunities for cross-contamination or blowing off un-cured powder on powder coated parts.Electric infrared ovens are the fastest way to heat a part. For extremely small spaces and fast line speeds, electric infrared energy will transfer the infrared energy faster than gas catalytic infrared ovens. gas catalytic ovens can bring down drying time drastically and also it uses less fuel bringing down energy costs.

Gas Catalytic Oven Can Cure Powder in 3-4 Minutes

Yes its true , gas catalytic oven can cure the powder with 3-4 minutes. it can also be used as a booster oven to bring down drying times and reduce the length of the conventional powder curing oven and reduce on investment costs. It can be retrofitted into an existing powder coating plant/line. Gas catalytic oven reduces your fuel/energy/running costs by 50% and increase your productivity. The gas catalytic oven uses a special radiation heat transfer technique which heats the powder and not the metal. Radiation heat is created by oxidizing the gas either LPG or natural gas using a catalyst. Gas catalytic ovens can be used on flat as well as complex shaped parts.

Prism has installed many gas catalytic ovens  around the world as well as in India along with its powder coating plants and Painting lines.
