As part of EMAC, ConeMac provides industrial power pack solution that integrated with air intake, air exhaust, cooling system, control system, transmission and hydraulic accessories, We also supplying special products such as explosion proof engine, generator and water pump set, as well as ultra-low temperature condition engine power pack. We provide full life cycle services for all customers, from design to power system supply, from installation to commissioning, from after-sales service training to spare parts supply, from trouble shooting to overhaul technical support.

1. It is synchronized with Cummins’ advanced design and sophisticated manufacturing, adapts to harsh working conditions, and has high-intensity and heavy-duty work capabilities.
2. The Holset wastegate valve makes the low speed performance more perfect and the power performance better.
3. The cylinder block and cylinder head adopt integrated design to prevent the occurrence of engine water and oil leakage. The parts are 40% less than other similar engines, and the failure rate is greatly reduced.
4. Using forged steel camshaft and crankshaft, high-strength cylinder design, many parts are cast on the cylinder, with high rigidity, high pressure resistance, good reliability and longer service life.
5.The cylinder liner adopts a platform mesh honing design, which effectively prevents oil leakage with a perfect geometric structure, and adopts advanced technology such as new piston ring components and gasket crimping molding to reduce oil loss.
6. Holset supercharger with integrated wastegate valve, low speed response and strong power.
