EAPIT series Hatch systems

The EAPIT hatch PIT system series consists of an underground chamber and hatch equipped with a counterweight opening system.

There are plugs on the upper part of the hatch to supply the aircraft with special current of either 400 Hz AC or 28.5 VDC. EA PIT can be equipped with a remote control and access system. On the lower part, there is a distribution box with a set of sockets.

We supply EA PIT assembled as much as possible to simplify its installation and connection.

We strongly recommend using ElectroAir GPUs with ElectroAir hatch PIT systems. By using them as a complete solution, it is possible to install GPUs far from the location of the PIT system.

We strongly recommend to use ElectroAir GPUs with ElectroAir PIT systems. Using them as a complex solution it is possible to install GPUs far from PIT location. Our automatic cable voltage drop compensation system makes it possible to install GPU 185 m away for AC and 35 m away for DC power supply (taking into account 15m of cable inside the PIT system).

If needed systems of compressed air and water (potable, blue, sewer) can be also built in to the PIT system. In addition, ElectroAir provides PCA and facility PIT systems. The PCA PIT system is equipped with a PCA rigid hose.

Underground chamber design is protected against foreign objects, dirt, rain and ground water ingress through the lid hatch. The corrugated outer surface of the cover eliminates slippage of an aircraft chassis, wheels of trucks and other vehicles. The cover is protected from spark formation due to collisions with metal objects. The cover holds up to 90t (according to EN 124 F900). The perimeter of the lid is marked with yellow and black warnings. The identification plate with a serial number and a complete set of the system is mounted onto inside of the hatch. The hatch is lockable to prevent inadvertent movement. The opening of the hatch is mechanical with a counterweight system.
