Electrical heaters for blow-by systems

MAHLE blow-by heaters are used in air and blow-by lines in order to prevent icing. MAHLE heaters use PTC technology and are available in modular variants, such as bar heaters, plug-in heaters (stand-alone), and solutions that can be integrated into the filter housing. The power range lies between 200 and 600 W, and the maximum flow rate is 200 L/h. Various control concepts such as thermoswitches, electronic switches, and independent controls using pressure and temperature are all possible. The advantages of MAHLE heaters are the optimized heating function and the potential for a high level of integration in the engine periphery.
