two Raptor XL400 cone crushers, a Cedarapids jaw crusher and various conveyors and material‐handling equipment. We have also installed a 50 kW MTU Onsite Energy auxiliary generator set that, in colder weather, is used to power heaters in the water jacket of the main generator and also keep the oil warm in the crushers." Tough Work A quarry environment provides a host of challenges for engines and generator sets such as dust, moisture, huge loads, extreme temperatures and long hours. Equipment that wants to prove itself in this situation must be strong, tough and persevering. The Series 4000 has experience operating day in and day out, under extreme conditions and in hard continu‐ ous operation, according to the company. The prime‐rated 1.5 MW generator set is powered by a 12v Series 4000 MTU diesel engine, known for its reliability, low fuel consumption and high load‐factor capabilities. The keys to the superior load acceptance and transient response are the engine's Advanced Diesel Engine Con‐ trol (ADEC) system and additional cylinder displace‐ ment per kW of output. ADEC systems have been developed and produced by MTU specifically for use with the very latest high‐per‐ formance diesel engine technology – designed not only for full control of the Common Rail technology in the Se‐ ries 4000, but above all for the management of frequent extreme loads and sudden load changes, which can be Durability was an important factor in Central Stone's application due to the number of hours the generator set needs to run every workday. "The ADEC not only helps the engine respond quickly to changing loads," said Michael Ware, sales engineer for Interstate Power Products, the local MTU Onsite Energy distributor, "but it maintains the combustion at peak efficiency for low emissions, low fuel consumption and high power output." In selecting the generator set for this prime‐power ap‐ plication, Central Stone worked carefully with Ware, who made sure that the generator set met all of Central Stone's specifications. "We were able to meet their expectations on price and availability, but of prime importance to them was the fact that the generator set could produce the required amount of power, day in and day out," Ware said. "As with all MTU Onsite Energy products, the generator set was factory tested to make sure that it met all rated out‐ put and performance criteria." overcome effortlessly and smoothly using this system. With approximately 20 percent greater cylinder dis‐ placement than some generator drive engines, the MTU Series 4000 has significantly more reserve horsepower and torque. This design philosophy also reduces inter‐ nal stresses on pistons, crankshaft, bearings and other moving parts and increases durability. Central Stone's new 1.5 MW generator set uses a 12v Series 4000 MTU engine, designed with approximately 20 percent greater cylin- der displacement than some generator drive engines for high reserve horsepower and torque. www.rockproducts.com ROCKproducts • OCTOBER 2011 23
