NITROGEN FILLING FOR AIRCRAFT TIRES TO PREVENT FIRE

A NITROGEN GENERATOR AT INTERNATIONAL AIRPORT GENERATES INERT GAS FOR TIRE INFLATION

In order to avoid damage to aircraft tires, they are filled with nitrogen at the airport. This is also the case at one of the largest international airports, which ranks among the top 20 with more than 60 million passengers annually. A nitrogen generator from Inmatec will soon provide the required inert gas here.

Aircraft tires are subjected to very strong forces during takeoff and landing. When landing, the strong friction of the runway and the brakes creates a very high temperature in the aircraft tires. Even at the start, the material load is enormous due to a higher starting weight (amount of kerosene) and a higher speed. The tires are filled with nitrogen to prevent fires from the extreme heat. But there is another reason for the N2 filling. Air contains water due to the humidity. At heights of several thousand meters, the temperatures drop to −50 ° C. Tires filled with air would freeze at this height. At high altitudes, however, nitrogen changes from a gas state to a liquid state at around −170 ° C.

The PNC 9000 OnTouch Generator delivered to Changi Airport this week generates 37.7 m3 of nitrogen per hour with a purity of 99.9%.
