At the ARA Show in Orlando, Fla., and at the recent World of Concrete show in Las Vegas, Makinex extended its compact three-phase power generation family with a new 23kW 480V model. Less than one third the size and weight of comparable towable and skid generators, the manufacturer said, the 23kW is the world’s smallest 3-phase 480V generator in this class.
“The small size of the 23kW generator makes it a no brainer for polishing and prep contractors,” said Jeff Durgin, a general manager in Gamka, N.J. “Now they can bring a 480V power source plus all of their equipment on a single trailer.”
Maneuverability at the job site is also important, with trailer and skid access getting harder to obtain on construction sites. Featuring large wheels and weighing only 410 pounds, the 23kW easily fits through doorways and can safely be taken in internal / external elevators to get power precisely where it is needed, without losing power over long cables from the street.
The 23 kW uses permanent magnet brushless alternator technology and has completely independent circuits for 120V and 480V. This guarantees clean 480V three-phase power that is unaffected by any load on the 120V circuit.
These advance alternator features result in 15 percent more power than from conventional copper wound alternators, the company said, and eliminates electronics used to regulate voltage. In addition, the generator comes with industry standard 50A, 30A and 20A outlets, and is able to run single phase and three phase equipment simultaneously.
In contrast, most conventional commercial generators only offer switchable voltage selection, and do not come with power distribution outlets as standard. This is the cause of countless cabling errors, which can result in accidental damage to the equipment being used.
“Most generators are built for stand-by applications, not the portable heavy-duty power applications you see in the concrete and flooring industry,” said Rory Kennard, Makinex CEO. “This market has been grossly underserved by generator makers. We aim to give them power products that are better suited to their needs.”
