20KVA Cummins generator set (silent type)

Product Introduction

Cummins Diesel Generator Sets (slient type) adopt the unified global design, production, and testing standards of Cummins, providing customers with reliable and integrated one - stop power generation systems. They perform excellently in normal, standby, and continuous operation.

Description du produit

Comply with the standards of ISO8528 - 2005 and GB/T2820 - 2009 《Reciprocating Internal Combustion Engine - Driven Alternating - Current Generators》.

The design and manufacturing units of the generator sets have passed ISO9001 or ISO9002 certification.

Cummins provides 1 year or 1000 - hour quality assurance (whichever comes first) for the generator sets, covering the engine, generator, and control system.

The professional service network across the country provides customers with 24 - hour after - sales service and technical support.

Performance Features

Advanced design and excellent manufacturing: Adapt to harsh working conditions, with high strength and strong heavy - duty operation capabilities.

Holset turbocharger: Smooth air flow, better power performance.

Integrated design: Such as cylinder block, cylinder head and other "one - piece multi - function" components, reducing connection parts by 40% compared with other same - class engines, greatly reducing the failure rate.

Outstanding reliability: High - strength cylinder block and crankshaft, high - strength cylinder body design, high rigidity, strong resistance to high pressure, longer service life.

Platform - like oil - proof channel design: The perfect geometric channel effectively prevents oil leakage of the machine.

Rotor high - pressure oil injection: Lower fuel consumption and effectively reduce noise.
