Ecoair has custom designed high output, high efficiency alternators with voltages ranging from 36V through 90V. These specialty alternators can be used in DC gensets and vehicles that have a special need for higher voltages. If the operating range of the system is relatively fixed and in the area of 6,000 to 8,000 alternator RPM’s, then the output can be as much as 5 to 15 kW.Eco-Tech alternators make use of permanent magnets, thereby optimizing alternator efficiency and power density. A high efficiency rating of 90% has been achieved. Where space is limited and high output is needed, the Eco-Tech alternators supply as much as two and one half times the output of conventional alternators.
