At the largest airports, passenger and cargo aircraft take their fuel from underground jet fuel pipelines. While a tanker truck can only carry 40,000 liters of fuel, for example an Airbus A380 can fuel up to 310,000 liters. Therefore, fuel transfer from tankers to aircraft requires a very long time. Therefore, these airports use hydrant dispensing trucks that pump jet fuel from the pipeline to the aircraft. Tanker trucks take the pressurized fuel with 10 bar in underground pipelines and reduce it to 3.5 bar. If the pressure remains too high, the fuel tanks on the wings of the aircraft can be damaged. In addition to time savings, this complex control and monitoring system also minimizes the risks posed by mobile jet fuel tanks.
In addition to the screw connection solutions that caused erroneous contact information during the process of modernizing the tanker fleet, the airline company Infraero in Brazil needed a PLC and I/O System that could both operate with spring-cage technology and operate in explosive environments. WAGO solution partner Planen Automação has created a complete solution with WAGO controllers and Ex-i / O modules that can be used with standard I/O cards and do not require additional zener barriers. It has 39 WAGO automation system equipped tanker trucks by reducing the dimensions of the control cabinets with the EX-i modules of WAGO, which has certification according to Brazilian standards.
