EcoJet and JuDy by OTTO JUNKER

Simmerath-Lammersdorf, 20.11.2023 – OTTO JUNKER, a leading supplier of high-quality melting and heat treatment plants presents two pioneering products which will help shape the future of metal processing: EcoJet, the latest product on the market, and JuDy, a proven solution which, together with EcoJet, will be an unbeatable combination. These future-oriented solutions allow an extremely efficient preheating of bars and billets and environmentally friendly heating without using fossil fuels while at the same time minimizing costs. With these furnace solutions, OTTO JUNKER offers a sustainable and cost-efficient alternative for the industry.

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.

Potential fields of application

EcoJet and Judy are not only technological milestones but also offer a wide range of options for various branches of industry. The furnaces can be used for a huge number of applications in order to improve efficiency, minimize environmental impact and lowering costs.

Examples of branches where a significant additional value can be achieved:

Metal processing and foundries: In the metal industry, EcoJet and JuDy can help optimizing energy consumption, speeding up production processes and improving the quality of the final product. This is of particular importance for the production of aluminium and copper.

Renewable energies: Precise heating processes are of major importance in the solar energy, wind energy and battery production fields. EcoJet and JuDy offer sustainable solutions for the production of components for these fast growing sectors.

Automotive industry: The automotive sector can benefit from the advantages offered by these innovative furnaces by the precise heating of billets and other metal parts, making the manufacture of automotive components more efficient and environmentally friendly.

„The introduction of EcoJet and JuDy represent an important milestone in our continuous technological evolution. With almost 100 years of experience in the design and manufacture of industrial furnaces, we have developed these products in order to fulfill the increasing demands of our customers. Our innovative strength and the high efficiency of these furnaces are the result of our efforts over the course of several decades.”
