How QBOIL® works
GEA QBOIL® combines fed-batch wort boiling, direct heat recovery and an integrated stripping process in a single, highly efficient system. While lautering is still in progress, wort is continuously fed into the kettle, enabling the energy released during boiling to be recovered and immediately reused for preheating incoming wort.
At the same time, a dedicated stripping column efficiently removes unwanted volatile compounds such as DMS, ensuring effective aroma management while maintaining low evaporation rates. By combining precise process control with direct energy recovery, QBOIL® reduces thermal stress on the wort and creates a transparent boiling process that balances beer quality, operational flexibility and energy efficiency.
QBOIL® benefits at a glance
- Significant energy savings - Direct heat recovery, minimized transfer losses and optimized process control help reduce thermal energy demand during wort boiling.
- Consistent beer quality - Adjustable boiling parameters help balance flavor consistency, volatile compound removal and energy performance.
- Operational flexibility - QBOIL® adapts to changing production schedules, seasonal fluctuations, variable brew sizes and start-stop operation.
- Full process transparency - Measurable energy input and clear process data support improved monitoring, documentation and control.
- Sustainability support - Lower energy demand, reduced losses and improved efficiency support brewery sustainability targets and operating cost reduction.
- Seamless retrofit integration - The compact system design makes QBOIL® suitable for modernization projects where space is limited and disruption must be minimized.
Technical highlights
- Direct heat recovery within the same brew - Use the energy released during boiling directly to heat incoming wort in the same brew, reducing external heat demand and enabling clearer, brew-specific energy accounting.
- Controllable boiling parameters - Fine-tune boiling conditions to balance flavor consistency, energy efficiency and production performance according to brewery-specific objectives.
- Direct energy measurement - Monitor, document and optimize thermal energy input throughout the boiling process, creating a new level of process transparency.
- Fractionated boiling technology - Integrate boiling into the brewery's overall energy strategy while maintaining effective volatile compound removal and low evaporation rates.
- Reduced fouling potential – Controlled thermal energy input supports stable heat transfer conditions and may contribute to reduced fouling and longer stable operating periods.
- Demand-based operation - Process transparency creates the foundation for condition-based optimization strategies, supporting more efficient plant operation and future digitalization initiatives.
Resource-efficient solution
As one of our most resource-efficient solutions, GEA QBOIL carries the Add Better label.*
QBOIL enables energy efficient wort heating and boiling. This reduces energy consumption by 35% compared to other energy recovery systems for wort heating and boiling, resulting in a higher energy efficiency, less carbon emission and reduced thermal stress.
*The Add Better label relates to the serial product GEA QBOIL, released in August 2025. The comparison refers to its predecessor model, other energy recovery systems on the market e.g. mechanical vapor recompression for wort boiling.

The water equation
Across Europe, drought is a recurring reality – and no longer confined to the south. While water increasingly shapes where industries locate, its value is determined by local context. There are many technological routes to water efficiency in industrial processes, but location, energy needs and other factors are also key.
