The heater operates quietly while consuming minimal electrical power and fuel. Choose from an installation mounted outside, in the double-floor or inside the vehicle. The integrated altitude sensor constantly ensures an optimal combustion process in altitudes up to 2,200 m – under lower air pressure and with a lower oxygen ratio.
The Air Top Evo models feature an in-built air pressure sensor as standard.
