eProp proportioning system for fluorine-free foam extinguishing agents

New requirements for foam extinguishing technology

The transition to PFAS-free foam extinguishing agents is fundamentally changing the requirements for proportioning technology. Fluorine-free foams exhibit a wide range of flow properties and can be highly viscous or structurally viscous, depending on the product. Here, conventional proportioning systems often reach their limits.

eProp was developed specifically to meet these requirements. The system enables high- precision proportioning of water-like, highly viscous and structurally viscous foam extinguishing agents and ensures a stable proportioning rate even with fluctuating back pressure, temperature and viscosity.

eProp is VdS-approved  

Six reasons for eProp

  High airflow rates without additional pressure loss in the extinguishing water line.
  
  
• Flexible integration
  Free positioning components for both new and existing fire protection systems.
  
  
• VdS-approved
  Tested for water-like, highly viscous and thixotropic agents.

Challenges for operators

Retrofitting to PFAS-free foam extinguishing agents
The ban on PFAS-containing extinguishing agents requires the retrofitting of existing systems. Fluorine-free foam extinguishing agents frequently exhibit different flow properties than conventional foam extinguishing agents.

Different viscosities
F3 foams can be highly viscous or thixotropic. Their properties change as they flow. This significantly increases the requirements for proportioning technology.

Ensuring long-term operational reliability
Insurers and operators expect a consistent fire-extinguishing performance. The proportioning process must function reliably even under varying conditions.


Integration into existing systems
Many operators want to continue using their existing infrastructure. New systems must be able to be integrated flexibly.
