Luckin Coffee: Fire Protection for Coffee Roasting Processes

Fires as part of routine operations

Regular fire and smoke incidents in the hot-air toaster section at Luckin Coffee are to be detected and stopped using an intelligent fire protection system – the GreCon PROTECTOR. The GreCon system exceeds the customer’s expectations by minimising material loss and boosting efficiency.

Toasters as a source of risk

Luckin Coffee is one of the largest coffeehouse chains in China. The company operates more than 13,000 outlets (2025) and relies on highly digitalised and automated processes – from ordering to preparation. The focus is on scalability, speed and digital convenience – including production.

In the hot-air toaster section at Luckin Coffee, fire and smoke incidents occurred regularly – on average once per month. The cause was sparks in the process, leading not only to safety risks but also to disruptions and cleaning requirements. Given the pace and volume of production, the company sought a low-maintenance solution that ensured safety while at the same time boosting efficiency.

From risk to solution in a few weeks

The parameters of the affected system were analysed and the framework conditions for system installation defined in order to establish a solution that would respond reliably while meeting the high production speed. This highlighted the high level of expertise Fagus-GreCon’s fire protection specialists bring to customised plant planning.

Systematic process protection at the source

Luckin Coffee opted for a fire protection concept from market leader GreCon. The system was installed at the critical points in production, where it detects potential sparks and automatically diverts the affected material.

A key advantage: the diversion valve opens and closes in a split second – keeping material loss to a minimum, far below the customer’s expectations.

The GreCon system also provides extensive data to help optimise the production process, particularly by adjusting toaster parameters such as working temperature and air supply.

The future of industrial fire protection

For over 50 years, we have been developing tailor-made industrial fire protection concepts for every individual challenge in industrial fire protection – reliable, practical and precisely tailored to your processes.

With GreCon PROTECTOR, we are now consistently continuing this approach: as an intelligent, next-generation industrial fire protection concept.

To achieve this, our protection concept combines the best components for

detection (SCOUTS),
processing (MISSION CONTROL and RANGER)
and response (HUNTER)

in a single system solution. Together, they form an intelligent protection system that not only secures against hazards, but also thinks for itself. The result is a modular, intelligent and decentralised networked industrial fire protection system that can be flexibly adapted to highly specialised industrial processes.

Rapid execution, lasting impact

The project began in May 2025, installation followed in June – and since July the system has been in full productive use. Ongoing optimisations are based on the collected operational data, with further process improvements carried out in parallel.

Smart fire protection as the new standard

Luckin Coffee is currently assessing how the principle of proactive process monitoring and rapid response can be applied to additional lines.

The project clearly demonstrates: intelligent fire protection not only increases safety – it also enhances the overall process.

Figures that speak for themselves

Figures that show how the GreCon PROTECTOR system ensures safety at Luckin Coffee while also boosting production efficiency:

Fire/smoke incidents: Before approx. 1/month → After 0
Spark events: Reduced from approx. 70 to approx. 25 per month
Material waste: Less than 2 kg per day – clearly below customer expectations
