The CombiBox pits

The CombiBox pits are made of galvanized steel and designed and manufactured for 100 years of in-ground use. The pits are load tested and certified for a 100-tonnes of load pressure i e the nose wheel of a widebody aircraft. The pits are equipped with state-of-the-art technologies for delivering 400Hz, PCA, Water, Jet fuel and many more service media.

400Hz – Electricity

 The 400Hz system consists of a converter supplying a pit installed close to the aircraft connection point. The
pit contains a light weight cable with a connector.

PCA – Air Conditioning

From the PCA ServiceUnit, air is supplied through an underground duct to the pit which contains a  heavy duty hose.

Portable Water

The central potable water plant supplies the pit through underground pipes keeping the water in constant circulation. The aircraft will get the water supply through a flexible filling hose, placed in the pit.

Waste Water

The lavatory system consists of a central vacuum unit connected to the pits. This enables central collection of waste water. Besides a vacuum hose, the pit conntains a flush water hose for tank cleaning and sanitary chemical injection.

Jet Fuel

The fuel is then transferred from the pit to the aircraft by a fuel dispenser truck. The Jet fuel pit in the apron is connected to the airport fuel distribution system via underground fuel lines.
