The TLD ACU-804 Series Air Conditioning/Heating units represents a comprehensive range of self-contained, highly portable air conditioning/heating units meticulously engineered to meet the needs of single-connection aircraft worldwide. With ample capacity to efficiently establish and sustain comfortable cabin temperatures, the ACU-804 (60 Ton) is adaptable to narrow and medium-bodied aircraft, regardless of the prevailing climate.

Distinguished by its straightforward yet robust design, this system integrates a diesel engine directly linked to both the refrigeration compressor and blower, showcasing the unique "TLD Direct Drive" technology. A hydraulically driven condenser fan efficiently dissipates waste heat in an upward direction, rendering it impervious to performance fluctuations caused by variable wind conditions while significantly reducing heat and noise emissions within the immediate ramp vicinity.
