"Five key benefits placing liquid-cooled ahead of air-cooled engines are low noise, improved performance, longer life, all-weather/all-purpose and easy low-cost maintenance," the company said.
Perkins Australian manager Laurie Phillips said the units were "flexible, accessible and efficient".
"Only the liquid-cooled engine can offer the flexibility to maintain operating efficiency throughout the whole spectrum of work cycles and ambient temperatures," he said.
"The system is designed to offer the required cooling needs when the engine is running at maximum capacity, which thermostatically changes when there is less load on the engine, providing optimum operating efficiency and low specific fuel consumption."
The unit's power rating is 26-300hp (19.5-223.5kW), allowing a wide range of uses. The lower surface temperature of liquid cooled engines enable a far lower temperature than do air cooled engines making them particularly suitable in specialist applications where fire or explosion hazards exist.
Improved access enabled easier maintenance, and the low noise output negated the need for sound-reduction canopies, Perkins said.
Powerpaks are available through Allight in Australia.
