APA-10 is hybrid type GPU, equipped with diesel engine for continuous power and batteries for engine starting mode. Lightweight and manoeuvrable unit is perfect for indoor and outdoor usage. Its relatively small size and extreme agility allows bringing the rectifier to any desired position.

Reconditioned Units

Old ground power units are often removed and scrapped to make way for new projects or expansions, however they are often repairable and can be used for other applications. AXA 2300 units are still widely used on airports around the world. The 2300 units operate to the same high standards as the newer units, and when properly maintained can still be used effectively. We reclaim AXA 2300 units in order to renovate and recondition them for smaller airports, aerodromes, heliports, or for any application which may not have the budget to cover the install of new units.
