Designed for refuelling hydraulic oil systems and cooling systems of aeroplanes and helicopters with liquids. The tanker body contains three tanks for storing liquids and a pneumatic system providing overpressure in the tanks.

Fluid from the tanker to the aircraft (helicopter) systems is supplied through flexible hoses by displacement with filtered nitrogen (air). The tanker can be equipped with tanks for liquids in various combinations. The tanks are easily removable. This makes it possible to use them outside the fuelling unit.
