Beijing Avespeed Commercial & Trading Co., Limited is the leading manufacturer and supplier of diesel engines for marine propulsion, marine Gen-sets, stationery Gen-sets and power plant applications in China. AVESPEED manufactures diesel engines with unit output from 150KW to 4500KW, which can be used as propulsion of merchant vessels and special vessels from 1000 to 30000 tons DWT. AVESPEED manufactures marine auxiliary diesel generators with unit output from 150KW to 4500KW and stationery HFO generators with unit output from 500KW to 8000KW.
AVESPEED designs and builds turn-key power plant with an output up to 100MW as base load power plant, peaking power plant or industrial self-captive power plant in cement, textile, mining or oil and gas industries etc. The power fuel can be diesel oil, bio-diesel, heavy fuel oil (HFO) or bi-fuel. AVESPEED has been set up more than 200 heavy fuel oil (HFO) power plant projects in the world in recent years, especially in Nigeria, we have set up more than 60 HFO power plant projects there.
All of our marine diesel engines have achieved type approvals and work test approvals of, CCS, China Ships Inspection Bureau, and China Fishing Ships Inspection Bureau. Many products are rated as "National Grade New Products" and "Industry Brand Products" and awarded with "National Prize for Progress in Science and Technology", Now AVESPEED diesel engines are widely used for deep sea fishery, inshore fishing ships, ocean shipping, inland water navigation, passenger cargo ship transport, harbor tug, engineering ships, enforcement ships, naval auxiliaries etc.
New energy products developed in recent years including natural gas generator sets, biomass generator sets, tyre oil/vegetable generator sets and dual-fuel generator sets with unit output from 50KW to 1000KW.
AVESPEED also involves in the development and manufacture of the crystal silicon (mono and poly) solar panel/module, photovoltaic system, and other photovoltaic products. We supply solar panels ranging from 45W to 290W. AVESPEED's on-grid and off-grid inverters are the sole in China certified by TUV. The PV inverters range from 1KW to 1000KW.
