Precise Dosing Technology for the Energy Transition – ViscoTec Solutions for Renewable Energy
Whether solar energy, energy storage, wind power, or hydrogen: In the production of renewable energy systems, precise and repeatable dispensing is crucial for quality, service life, and cost efficiency.
ViscoTec provides fully automatable dispensing systems for demanding one-component and two-component materials. Applications range from bonding and interconnecting battery packs, to bubble-free application of thermal interface materials, and reliable sealing of critical components, even in offshore environments.
Our systems dispense volumetrically, reliably, and material-efficiently, even at high cycle rates and under changing production conditions.
Application Examples
Energy Storage
Bonding, Interconnection, and Thermal Management: Dispensing Solutions for Battery Systems
High-performance and durable energy storage systems are a key enabler of the energy transition, from residential storage units to industrial and grid-scale battery systems.
ViscoTec dispensing systems support reliable bonding and thermal stabilization of battery cells and modules. Typical applications include semi-automated and fully automated bonding of cell components as well as bubble-free, uniform application of thermal interface materials.
This improves thermal management, reduces hotspots, and increases the service life of the entire energy storage system.
New concepts such as repairable and recyclable battery modules also benefit from precise material application, for example through releasable bonds and interconnections. This helps conserve raw materials and enables more economical service concepts.
Solar Modules
Bonding & Sealing: Reliable Dispensing for Durable PV Modules – From Frame Bonding to Junction Boxes
In solar module manufacturing, consistent bead geometries, defined volumes, and robust process control are essential. ViscoTec dispensing systems automatically apply adhesives and sealants for applications such as frame bonding as well as junction box attachment and potting.
Volumetric dispensing ensures consistent, bubble-free application regardless of viscosity or filler content. This increases the mechanical stability, weather resistance, and electrical insulation of PV modules, contributing to consistently high energy yield over their entire service life.
ViscoTec systems also support efficient and stable processes in metallization and silver paste handling. Critical materials such as silver pastes can be dispensed precisely and volumetrically, reducing material consumption and production costs.
The low-shear conveying principle is particularly suitable for high-solids-content pastes, both for highly precise dispensing and as a reliable feed system for screen-printing processes. Consistent material quality and stable process control help maximize solar module performance throughout its lifecycle.
Your Advantages in PV Manufacturing:
- Highly repeatable, fully automated dispensing for consistent quality
- Processing of 1-component and 2-component materials
- Easy integration into semi-automated and fully automated production lines
- Reduced material consumption through precise application (beads, dots, patterns, or surface coating)
- High axis speeds while maintaining exceptional dispensing accuracy, even along long edge geometries
- Lightweight dispensers, including 2-component systems with mixing heads, for dynamic automation systems
Wind Energy
Sealing & Corrosion Protection (Onshore/Offshore)
In wind turbines, exposed components such as bolts, slots, and screws must be reliably protected, even under extreme environmental conditions, particularly in offshore applications. ViscoTec dispensing technology enables reproducible and process-reliable sealing of these critical components.
- Precise application: Highly repeatable dispensing of 1-component and 2-component materials (mixing ratios up to 20:1)
- Flexible processes: Dot dispensing, bead application, and cavity filling
- Reliable 2-component processing: Homogeneous mixing for dependable curing
ViscoTec systems and dispensers enable complete sealing of sensitive areas, providing long-lasting corrosion protection in demanding environments.
Depending on the application requirements, the dispensing process supports protection up to high corrosion protection categories (e.g., C5/CX according to ISO 12944), including environments with high humidity, aggressive atmospheres, and salt spray exposure.
Fuel Cells
Sealing, Bonding, and Dispensing – Precision Even at the Smallest Volumes
In fuel cell manufacturing, defined volumes, clean bead geometries, and short cycle times are essential. ViscoTec dispensing systems apply sealing and bonding materials with high precision and repeatability, even on complex geometries, such as sealing bipolar plates.
Our systems are designed for cost-efficient production and support short cycle times, from prototype manufacturing to high-volume production.
Thanks to low-shear material handling, even materials with high solids content, such as highly abrasive pastes, can be dispensed safely and accurately.
The modular system design provides maximum flexibility and scalability. Production concepts can be adapted to new materials, changing geometries, and increasing production volumes.
