A WEH^® fuelling system for refuelling buses and trucks is also available. The TS55 CNG consists of a fully assembled housing with an integrated large receptacle and enables easy retrofitting of buses and trucks to compressed natural gas. The converted vehicle can be easily refuelled from the outside by simply removing the fuel tank cap and connecting the nozzle to the receptacle. Then refuelling can start. The integrated WEH^® TN5 receptacle ensures rapid filling with a high flow rate and reduced noise during refuelling. The fuelling system consists of two preinstalled housings for mounting into the vehicle.
