Roof-mounted AC system – AC353-5

The 5th generation AC353 has a new look. Its minimalistic design, as well as its clear lines and contours, makes the AC353-5 unmistakably more puristic and dynamic than ever before.

Reliable, durable and robust: the AC353-5 combines the groundbreaking features of the AC353 product family into a single system. The reduction in refrigerant and electricity consumption, which is a saving of up to 10% compared to the previous AC353 G4 generation, ensures a sustainable energy balance. With a cooling capacity of 27 kW in the basic version through to the powerful variant with a 6-cylinder compressor and a cooling capacity of 48kW, the AC353-5 is designed for use in both temperate climate zones and hot countries. With a switch-off temperature of 46°C and a cooling capacity of 27kW, the Tropic Version AC353-530 is the light and compact alternative for use at high ambient temperatures.
