Coolant particle filter

MANN+HUMMEL coolant particle filters protect both fuel cells and high-voltage battery systems from contamination.

During the reaction of hydrogen and oxygen in the fuel cell, heat is generated which must be discharged. The coolant particle filter from MANN+HUMMEL removes harmful particles from the cooling circuit in the main flow. Contaminations in the coolant circuit can either block narrow cooling channels or cause wear on the coolant pump. Filters with pressure drop-optimized design allow clean coolant in the main flow and thus reliably protect the fuel cell stack as well as components of the cooling circuit.

Coolant particle filters also provide reliable protection for high-voltage battery systems: The inflow of liquid-cooled batteries contains harmful particles, which can block cooling channels and thus lead to pressure loss and overheating of the battery. With its extensive experience in the filtration and separation of liquids, MANN+HUMMEL has developed a coolant particle filter for high-performance batteries. It removes harmful particles and thus protects the system from pressure loss, wear and overheating.

New filtration solutions for clean mobility

Electrified drives help to reduce CO2 emissions during driving and to decrease air pollution caused by pollutants such as NOX and particulate matter. The resulting increase in the importance of alternative drives is currently accelerating the development of new filter applications at MANN+HUMMEL.

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.
