Lubricant manufacturer Zeller+Gmelin is once again represented at this year’s Battery Show Europe in Stuttgart. New gapfiller products for thermal management in electric and hybrid vehicles and for charging infrastructures will be presented at stand E60 in hall 6. Sustainable specialty lubricants for forming technology and sheet metal working will also be presented.
As an established partner to the automotive industry, Zeller+Gmelin is increasingly expanding into the field of e-mobility. To this end, the Eislingen-based company has developed innovative thermal management products, including silicone-free gap fillers for battery systems, coolants for direct battery cooling, for controlling the temperature of PEM fuel cells and for use in cooling circuits in vehicles or charging stations.
“Our Divinol Thermosure products are designed to significantly improve thermal performance in electric vehicles and their charging infrastructures,” explains Christian Stapper, Product Manager at Zeller+Gmelin, with regard to the trade fair. “Thanks to their advanced properties, they make a significant contribution to preventing overheating and increasing the performance and service life of electronic components.”
Thermosure for efficient thermal management
The exhibits presented in Stuttgart include the dielectric coolant Divinol Thermosure BCF 10, which is ideal for direct battery cooling by means of immersion. With a high thermal conductivity of 0.136 W/mK at 60 °C, it offers reliable heat dissipation and helps to prevent overheating.
For applications in battery systems and power electronics, Zeller+Gmelin offers the silicone-free Divinol Thermosure GF28-27 system, among others. This solution is characterized by a high thermal conductivity of 2.8 W/mK and is particularly suitable for automated application, which enables precise and efficient use.
Another highlight of the Thermosure range is the glycol-based coolant Divinol Thermosure FC 40, which was specially developed for controlling the temperature of PEM fuel cells. With a density of 1040 kg/m³ and a low viscosity of 3 mm²/s at 40 °C, it ensures effective cooling and also offers an electrical conductivity of 1.14 μS/cm at 50 °C.
Ready for rapid use in vehicles and charging stations
The trade fair range also includes glycol-based coolants with high frost and corrosion protection, which are used in the cooling circuits of vehicles, charging stations and other applications. They are free of nitrite, borate, amine, phosphate and 2-ethylhexanoic acid, which makes them particularly environmentally friendly and safe in their respective areas of application.
The product range includes the label-free coolant Divinol Thermosure PG, which is based on propylene glycol and offers optimized copper compatibility. It is available as a ready-to-use ready-mix, which facilitates application and ensures greater efficiency in use.
For applications that require a blue-colored solution, Zeller+Gmelin offers the coolant Divinol Thermosure EG Blue. This coolant is based on ethylene glycol and was also developed with optimized copper compatibility. This product is also available as a ready-to-use ready-mix.
Forming and cleaning media for e-mobile production
Finally, Zeller+Gmelin supports the metal and electrical industry with the latest technologies for the production of electric and hybrid vehicles and their components. The experts will be presenting trade visitors with comprehensive solutions for metal processing and cleaning media for the production of cylindrical and prismatic cell housings for electrified vehicles.
“From the initial forming and cutting to the subsequent cleaning and preservation, we can provide the entire portfolio of products for the manufacture of these cell housings,” emphasizes Christian Stapper. In addition to forming and cutting oils, the product range also includes cleaners, hot melts and lubricating greases, which are used in steel and aluminum plants worldwide.
“We are looking forward to presenting our latest technologies to trade visitors at the Battery Show,” summarizes Christian Stapper. “At stand E60 in hall 6, you can get to know the future of thermal management in e-mobility.”
