Polar 120 HD was born as a result of Polartherm's and Finnair's long term co-operation and development. Polar 120 HD and its earlier versions have been in use on airports since 1985 and it has been proven a very reliable and robust heater. The Unit is compact and easy to move by one operator due to its long towbar, single axle design, and good balance.
120 HD has a Yanmar - GTS engine-generator for producing the electricity needed to run the fan and fuel burner.
