The mobile paralleling box from KOHLER Power Systems enables users to combine different size generators with different fuel types. Designed for use with KOHLER’s LP or natural gas and diesel mobile generator line, four boxes can be used to parallel up to eight generators. The KOHLER Decision-Maker 3500 digital controller, standard on all KOHLER LP or natural gas and Tier 4 Final diesel mobile generators, provides the paralleling intelligence and network communications. 800/544-2444; www.kohlerpower.com.
