Product Details

Battery Cooling Silicone Hose For Fuel Cell Bus Electric Bus Hybrid Vehicles


The bus cooling system absorbs heat from various systems associated with the hydrogen fuel cell engine and expels excess heat to the atmosphere. The silicone hose applied in this system is buit of food grade silicone as inner tube,

multiple plies of silicone reinforced with aramid fabric to enhance its high or negative pressure resistance. The outer walls use high-performance silicone that withstands high and low temperature ranging from -50~+260℃, and has excellent ozone, aging and weather resistance.



Result from the high cleaness requirement by the fuel cell, in addition to use food grade silicone liner, Goodyou cleans fuel cell hose using deionized water in dust-proof workshop to better control the particles.
