ACU-2000

Aircraft Heating Unit

The ACU-2000 Series trailer-mounted aircraft heating units offer a range of models that deliver from 500,000 up to 1,000,000 Btu/Hr of clean pressurised, heated air to all aircraft or facilities equipped with a standard 8-inch (203mm) connector. The unit provides filtered air to maintain passenger comfort during aircraft turnover or to maintain the cabin temperature during layovers to prevent damage to any onboard plumbing systems.

The gasoline engine supplies the thermal and mechanical energy required to operate the heating system. In the 500 KBtu/Hr model the inlet air is heated by the blower heat of compression and then passes through a heat exchanger that recovers energy from the engine coolant circuit. In the 750 KBtu/Hr models an additional heat exchanger recovers energy from the engine exhaust.

For the most severe environments, the 1,000,000 Btu/Hr model combines these approaches with electric resistance heating elements powered by an external 90 KVA GPU connection (GPU not provided). The recovery and use of engine waste heat make the ACU-2000 a very energy efficient unit.

Features:

Reliable and durable construction

High fuel efficiency and machine output

Local factory-trained support available

SCU-025

Sub-cooling Unit

The SCU-025 is a supplemental, portable air conditioning unit that is designed to provide sub freezing air to aircraft in tandem with any large ACU. The SCU accepts cooled air from any suitable ACU and further cools the air to about minus 10°C (-15°F). This patented concept provides exceptional cooling efficiency while minimizing acquisition costs for subfreezing air systems. Equipment owners can continue to use their existing fleet of ACU’s in tandem with the SCU, resulting in a very low cost yet effective solution.

The simple yet rugged design consists of a diesel engine directly driving a refrigeration screw compressor and condenser fan. This is the unique “TLD Direct Drive” technology which provides more cooling for the same input power, and has a reduced part count, resulting in higher reliability and lower total cost of ownership.

The belt driven condenser fan exhausts waste heat directly upward making the unit immune to performance fluctuations due to varying wind conditions and minimizing heat and noise radiated to the immediate ramp area.
