The Himoinsa Kronos series of generator sets is supplied in four standby rating power nodes from 6 to 35kW. Kronos utilizes the very successful Hatz air-cooled engine, close coupled to a 12-wire brushless reconnectable generator end. Hatz engines are renowned for their reliability and ability to run unattended for considerable periods with minimum maintenance. Hatz engines are extensively used in constructions applications, and the Kronos series targets the prime, rental, oil field, and construction market that require reliable power for long periods and minimum down time.

Kronos sets are supplied in open and sound-attenuated configurations. Sound attenuated models incorporate the well-known Hatz Supra and Silent Pack ranges. Kronos is one of the few series of air-cooled diesel generators that is fully EPA and CARB approved, and can be operated in any emission regulated environment, including mobile for construction and rental.
