Ground power units (GPU) for aircraft operations

Air+Mak Industries Inc has been designing and manufacturing 400Hz ground power supply units for aircraft applications for more than 40 years and is a pioneer of digital 400Hz GPUs worldwide.

GPUs are manufactured from 40kVA-180kVA 400Hz AC and up to 2,500A 28.5VDC, in accordance with the latest emission regulations.

MAK GPUs are built with MAK 400Hz alternators with double bearing and the highest class of insulation.

They are manufactured to be towable trailer-mounted, self-propelled and skid-mounted for commercial trucks.

Air pollution-free static frequency converters / sold-state ground power units (SGPU)

Solid-state ground power units are similar to conventional GPUs in terms of rating and performance but use commercial mains supply instead of a diesel engine. These units are air pollution-free, reduce operational noise and are much more compact than standard GPUs.

The power ratings are the same as GPUs, of 40kVA-180kVA and 28.5VDC. They are available in two models, which are vertical and jet-bridge mount types.

Air start units (ASUs) for commercial jets

Air start units used to start commercial jet plane engines are manufactured from 100PPM to 400PPM based on engine requirements.

The ASUs are built with proprietary digital pressure control system, which automatically regulates the output air pressure / flow for different aircraft.
As with GPUs, ASUs are also manufactured to be towable trailer-mounted, self-propelled and skid-mounted for trucks.

Air-conditioning units (ACUs) for aircraft cabins on ground

Air-conditioning units used to cool aircraft cabins on the ground are made with an extensive capacity from 5TR to 150TR, and are also available with heating options based on ambient conditions and aircraft size.

Also known as ground cooling units, this type of equipment is built with direct-drive or electric-drive technology. Units are self-propelled and also manufactured for skid-mounting on trucks, as well as being towable when trailer-mounted.

Apron tractors (AT) for airport cargo / baggage dollies

Electric apron tractors are used for cargo / baggage dollies at airports, these units have a pull capacity of 4,000lb (2,500kg) and feature power steering, hydraulic brakes and ergonomic cabins.

A totally emissions-free unit, this is ideal for use in airports where the cargo hold is located underground and using diesel tractors is impractical.

Load banks (ALB / DLB) for airport ground power units

Load banks are used for testing / calibrating ground power units and static frequency converters over regular intervals. Units are made with similar power ratings of GPUs in 48kW-144kW 400Hz AC and 300A-2,500A 28.5VDC

MAK’s load banks are portable, robust and fully digital with a touchscreen display and load bank monitoring system (LBMS), which records operational parameters on a PC via USB.

All load banks come with a wheeled enclosure trolley for optimum portabilty.

Remote diagnosis and monitoring system (RDMS)

A unique feature across MAK’s ground support product range gives users the capacity to monitor equipment parameters and health anytime and from anywhere in the world.

A MAK Wireless Module (MWM) is fitted on the equipment with an M2M SIM card that uses mobile data to communicate the unit’s operational parameters at regular intervals to a Cloud server. This solution enables users to monitor performance from a computer or smartphone through a software application.

This solution records all operational parameters, fault alerts, maintenance schedule, AMC management, ad-hoc servicing record, order spares and a schedule to receive automated reports straight to your inbox.
