Freudenberg Performance Materials GmbH & Co.KG At a glance Project: Replacement of a gas-fired thermal oil system Industry: Technical textiles and nonwovens Location: Kaiserslautern, Germany AURA Solution AURA System: Thermal oil system Type of heating: Electric Heat transfer medium: Thermal oil Maximum temperature: 315°C Installed capacity: 1 MW The electrically heated thermal oil system ensures stable process conditions in nonwoven production while generating zero direct CO₂ emissions. Initial Situation Freudenberg Performance Materials is a globally leading manufacturer of technical textiles for a wide range of applications and is part of the Freudenberg Group. The family-owned company has set itself the goal of becoming CO₂-neutral by 2045 and is upgrading its existing systems accordingly.   At the Kaiserslautern site, the drum dryer required for nonwoven production was previously heated by a gas-fired system. The system generated a high level of emissions, was maintenance-intensive, and operated with low efficiency. AURA Solution AURA replaced the existing system with an efficient electrically heated thermal oil system, featuring a heating capacity of 1,000 kW and an operating temperature of 285°C. The new electrically heated system now operates emission-free, safely, and with minimal maintenance requirements. Thanks to the precise temperature control enabled by the system, the company benefits from improved process stability and energy efficiency. Und so geht es weiter…  In einem zweiten Schritt soll ein thermalölbeheizter Sekundärregelkreis an das vorhandene System angeschlossen werden. Dieser wird für einen weiteren Trocknungsprozess benötigt und nutzt dazu die verbleibende Leistung der neuen elektrisch beheizten Thermalölanlage. Diese Erweiterung befindet sich aktuell bei AURA in der Fertigstellung und wird noch in diesem Jahr in Betrieb genommen.  Wir freuen uns sehr, Freudenberg auf dem Weg zur CO2-Neutralität als Partner begleiten zu dürfen und bedanken uns für das Vertrauen!

Kroll & Ziller At a glance Project: Modernization of an outdated steam system Industry: Manufacturing of technical seals and flange connections Location: Germany AURA Solution AURA System: Electric thermal oil system Heating type: Electric Heat transfer medium: Thermal oil Maximum temperature: 300°C Power: 100kW The electric thermal oil system ensures a significantly more stable production process, reduced energy costs, and zero direct CO₂ emissions. Initial situation For over 80 years, Kroll & Ziller GmbH & Co. KG has been manufacturing high-quality sealing solutions – including for the food industry, chemical sector, mining, and drinking water supply. Industrial process heat is essential here to shape materials, cure them, and ensure long-term functionality.  Until now, the presses used in the vulcanization process at Kroll & Ziller were operated with a fuel-fired steam system – a setup associated with high energy consumption, intensive maintenance, and significant operating costs. The objective: A modern, efficient system to reduce the carbon footprint.  AURA solution In this project, we implemented two key technology shifts:  1.Transition from fuel-fired to electric heating: The new electrically heated system now operates emission-free, safely, and with minimal maintenance. Thanks to precise temperature control, Kroll & Ziller benefits from increased process stability and improved energy efficiency.  2.Conversion from steam to thermal oil as the heat transfer medium: Thermal oil can be operated at high temperatures with virtually no pressure, reducing requirements for pressure vessels, piping systems, and safety valves.
