Tropical (successor to Alfa) is a Greek manufacturer involved in machinery and vehicle development and production.
Its history is characteristic of a company which has made significant efforts to evolve in a country that effectively forbids production of locally developed passenger cars.
Instead, Alfa focused on the production of a variety of bus types, as well as air-conditioning and refrigeration units for commercial vehicles.
The company went out of business due to the crisis in the bus market in Greece (after imports of used buses were allowed), but it was re-founded as Tropical in 1991.
Since the late 1990s, Tropical has invested heavily in research and development of a wide variety of hydrogen-powered generators, appliances and vehicles.
