Stein Digiflex, innovative technologies:

What makes the Stein Digiflex® unique is the combination of innovative technologies:

  • Compact and efficient jet preheat furnace (JPF)
  • Reactive direct fired furnace (DFF)
  • Low inertia radiant tube heating furnace (RTF) 
  • AdvanTek® combustion system, which guarantee up to 20% less fuel consumption and minimum NOx emissions
  • Unique FlashCooling® system for ultra rapid cooling solutions 
  • Virtuo® thermal solution for increased yield & quality, and reduced OPEX
  • Compact Aeris®, after-pot cooling solution after a galvanizing section

These unique technologies enable the steel making process to generate more profit per year vs conventional technologies. 

AdvanTek® burners for annealing & galvanizing furnaces

AdvanTek® WRT 2.0/3.0 self-recuperative burners can be integrated into existing radiant tube furnaces or implemented in new radiant tube furnaces in annealing and galvanizing lines and are available for a power range of 50 – 200 kW. The AdvanTek® WRT achieves high temperature uniformity along the W-tube, with high energy efficiency and improved environmental performance for 7 and 8-inch radiant tubes.

Technical highlights include:

  • Fuel: natural gas, coke oven gas, mixed gas or any site generated gases and can be customized to the customer’s available utility conditions
  • They are able to achieve up to 80% burner efficiency and reduce NOx emissions to less than 50 ppm.
  • Full compliance with the latest European standards and particularly EN 746-2
