The expanded line QEC range of containerized generators includes two dedicated models for the U.S. and Canada, which have been designed for multidrop, prime power and critical standby applications for mining applications. The QEC 800, QEC 1000 and QEC 1250 are available for the global market (50/60Hz switchable) and the QEC 950 and QEC 1200 are dedicated 60Hz, EPA Tier 2-certified for the U.S. and Canada. To minimize maintenance and service costs, the QEC range comes with long service intervals of 500 hours, easy removal of the aggregate engine-alternator via the slide in/out concept, large access panels, a mechanical cooling system and several service tools. Additional maintenance features include heavy-duty dual stage fuel and air filtration, a dedicated door for easy cleaning of the engine coolers and directly accessible power cable connections. An optional Qc4003 controller can put two or more QEC models into parallel for a flexible power solution for loads that exceed the output capability of a single generator set. This type of power management system (PMS) can also be used to provide continuous power when one of the gensets needs to be shut down for scheduled maintenance or repair.
