Ion exchange filter

To keep the electrical conductivity of the coolant below the permissible limit, ions must be effectively removed. MANN+HUMMEL offers two product families optimized for the respective area of application: OmniFlow for industrial applications and IonFree for automotive applications from passenger cars to commercial vehicles. 

IonFree - for automotive applications

Product benefits

  • Keeps the electrical conductivity of cooling liquid low

  • Automotive design for high capacity

  • Compact and openable design

  • Replaceable cartridge offers an easy service concept

  • Standard product offers lower cost

  •  

OmniFlow - for industrial applications

System expertise for fuel cell powertrains

Legislation governing vehicle emissions is becoming stricter, the climate debate and therefore also the development of alternative drives is gaining momentum. One promising solution is the fuel cell used to supply energy to an electric drive. MANN+HUMMEL has now developed an innovative air induction system for the cathode path in order to ensure an efficient supply of clean air to the fuel cell.

IonFree modular kit

The fuel cell is one option for balancing mobility and climate protection in the future. MANN+HUMMEL also supplies tailor-made filtration solutions for hydrogen propulsion systems. The ion exchange filters from the new IonFree modular kit reliably protect the fuel cell stack against dangerous short circuits and reduce system costs.
