Resource-Efficient Configuration
ReFlow Water-Saving Unit for Plungers
GEA ReFlow recirculates the plant process water used by high-pressure homogenizers to cool and lubricate plungers, making the operation of GEA machines more resource-efficient.
Combining efficiency with resource savings
Imagine adding value to your utilities savings and contributing to a more sustainable world. Only by choosing a GEA homogenizer.
GEA ReFlow recirculates the process water used by high-pressure homogenizers to cool and lubricate plungers. This reduces significantly the amount of treated process water or potable city water used. The unit can operate independently using its built-in control system, exchanging signals with the homogenizer and the associated process, or it can be fully integrated by incorporating the provided functional description into the process control system.
Key features and benefits
Resource-efficient
- Water flows back into the system for filtration instead of being wasted
- Up to 95% water savings and recirculation for all homogenizers*
- Recirculating water is compliant to safe water regulations
- Conductivity sensors to detect product leaks into the plungers cooling water
- Heat exchanger to remove heat from plungers and circulation pump
Safe and flexible
- Robust ceramic membrane to remove all bacteria and nearly all viruses, proteins and enzymes
- Flow meter to set required plunger cooling flow
- Backflushing possible
- Manual-CIP and Auto-CIP (Cleaning In Place)
- Sanitization at 100°
- Suitable for all homogenizers as well as a retrofit option

Reality check for biotech
The new GEA Application and Technology Center (ATC) in Sarstedt, south of Hannover, is neither a showroom nor a substitute for a lab. It is a place for testing, data collection and early decisions. This is where it becomes clear whether a biological concept can become a robust industrial process. That step is bigger than it may seem.
Shifts in food packaging: 4 trends
Thermoforming has long played a central role in food packaging. Now it is facing a major shift. As regulations tighten, materials evolve and costs rise, form fill seal lines must do more than run reliably – they now shape how food stays fresh, affordable and recyclable. Take a look at the key thermoforming trends informing the food packaging and delivery landscape.
