Sweden’s Atlas Copco has introduced two Tier 4 Final diesel generators from its QAS series.
The gensets are powered by an Isuzu 4LE engine that use a diesel oxidation catalyst in order to meet the emission requirements. Both systems generate 60Hz each. According to Atlas Copco, the systems ensure low noise levels for residential and noise-sensitive locations.
The generators are designed for heavy-duty applications. Large fuel tanks allow extended run times. Both replace the existing QAS 25 and QAS 45 gensets and use the same basic engine, enclosure and controls.
Due to minimising the number of service parts and increasing technician familiarity, lifecycle costs and therefore the total cost of ownership will fall, claimed the company.
Generator Power recently placed an order of 170 Atlas Copco generators of various sizes, worth $5.7m.
EPA adopted Tier 4 emission standards in 2004 for new off-road diesel engines in order to reduce hydrocarbons, carbon monoxide, particulate matter and nitrogen oxide. Tier 4 Final standards require a reduction to near-zero levels.
