In 1958, ZEXEL (then Diesel Kiki Ltd.) introduced its first airconditioners for automobiles in the Japanese market. Since then ZEXEL has been working closely with automakers, right from the vehicle development stage, in search of a truly comfortable passenger space based on human engineering. Electronically controlled variable-capacity compressors and other advanced technologies have been incorporated to implement the sophisticated, electronically controlled full-automatic air conditioning systems that promise the greatest comfort while reducing engine load.

ZEXEL offers a wide variety of airconditioners for passenger cars, vans, trucks, buses, construction vehicles, farm machinery, and rail cars, as well as refrigeration units for trucks and container vans.
