5TR / 30TR / 60TR / 70TR / 120TR / 140TR / 150TR & many more…

An ACU is used for supplying cold / hot Air into a parked aircraft's to sustain comfortable temperatures for passengers in relation to ambient conditions .The output air travels via One/Two hoses connected to the aircraft's under belly.

MAK design and manufacture Air Conditioning Units from 5TR to 150TR. Standard models are 30TR, 60TR, 65TR, 70TR, 110TR & 140TR manufactured as per commercial aircraft specifications. MAK has specially developed ACU's for corporate jets with 5TR capacity. MAK ACUs boast of 1 Lakh + hours of incident free operation and find satisfied customers among major civil airlines and defense organizations across the world.

MAK ACUs comes with a touchscreen control panel MAK GSEM V8-C and MAK RDMS-A feature rich fleet management software which transmits live operational data to a remote computer/mobile and alerts users in real-time of faults, alerts. With this software, users can plan maintenance schedules, ad-hoc service records, order spare parts... and much more, eliminating need for dedicated manpower per operation location.
