MAK Controls & Systems

The MAK Load Bank is a portable test instrument that verifies the output quality of aircraft ground power equipment before it is put back into service or connected to an aircraft.

The MAK diesel-driven GPU is a self-contained 400Hz alternating-current power supply designed to sustain aircraft electrical systems during turnaround without running the aircraft's own APU.

The MAK Pre-Conditioned Air (PCA) unit supplies temperature-controlled, filtered air to a parked aircraft's cabin environmental control system, allowing the aircraft to maintain a comfortable cabin temperature during ground time without burning APU fuel.

The MAK Aircraft Air Start Unit (ASU) provides high-pressure, high-flow air to initiate engine rotation on aircraft that require external pneumatic starting — particularly high-bypass turbofan types where APU-less cold starts are routine in line maintenance or remote parking scenarios.

The MAK GPCU Combo consolidates two conventionally separate pieces of ramp equipment — a pre-conditioned air unit and a DC ground power unit — into one self-contained mobile platform.

The MAK Static Frequency Converter (SFC) is a solid-state ground power unit that takes standard utility mains — 400/415V three-phase at 45–65 Hz — and converts it to the 400Hz, 200/115V three-phase power that aircraft avionics and systems require.
