Sustainable preheating with EcoJet
EcoJet is a preheater which combines maximum efficiency and environmental protection. With an efficiency of more than 95 %, EcoJet sets new standards in the emission-free preheating of bars and billets. Thanks to decades of experience in resistance and convection heating and by using state-of-the-art technologies including cutting edge flow simulation and calculations, OTTO JUNKER can offer specially-designed heater banks with a high power density for a wide range of applications. Temperature monitoring is by means of thermocouples in order to ensure optimum heat transfer. All the components of the EcoJet preheater are the result of in-house developments, engineering and manufacture guaranteeing maximum quality and reliability.
By using the EcoJet preheater, companies can not only improve their ecological footprint but also ensure their productivity in times of fluctuating gas supplies. With rapid heat-up times and precise temperature control, the furnace offers a sustainable solution combining environmental protection and economic efficiency.
JuDy: Precise temperature control with taper
JuDy (JunkerDynamicHeater®) is an induction-heated furnace which revolutionizes the final heating of billets. With an efficiency of approx. 58 % and its ability to produce a precise temperature profile in the billet across individual zones, JuDy offers a highly efficient production. The use of a ceramic melting protection tube considerably reduces energy consumption. Thanks to the OTTO JUNKER trough conveyor system, marks and scratches on the billet surface are avoided. By using the mathematical “Billet Pilot” process model, the heat can be applied in an optimized manner and the heat-up time can be reduced. Both the IGBT converter and the coils are core components produced in-house which are extensively tested and fine-tuned before shipment.
JuDy offers the flexibility required for special applications while at the same time guaranteeing a reproducible temperature profile. This solution complements electrically-heated preheating furnaces - as “stand alone”, parallel and in-line.
The best thing, however, is the combination between EcoJet and JuDy which, together, achieve an impressive efficiency.
