China Dongjing Environmental Protection Equipment Co., Ltd.
Dongjing develops and manufactures equipment for circulating, purifying and reclaiming industrial oil, covering design, production, sales and after-sales service. The company works to four stated commitments — quality, environmental responsibility, service and innovation — and continues to take in technology and management practice from the wider industry.
The equipment handles more than a hundred industrial oils, among them transformer oil, hydraulic oil, turbine oil, cutting oil, gear oil, EDM oil, quenching oil, slideway oil, hydrocarbons, kerosene, diesel and white mineral oil. It is in service in power generation, mining, construction machinery, factory equipment and marine applications.
Extending the service life of the oil instead of replacing it lowers purchasing cost and the volume of waste oil to be handled at the same time. That is the commercial case for the product, and the direction of the company's continued investment.
