In early August 2023, a distribution company in Jilin City consulted about oil filter equipment that could be used for filtering and dehydrating light fuel diesel, and supplied it to their own Congo cloth customers for use in China Gold Group's Congo cloth project. Mainly used for transfer filtration refueling of light diesel.

After multiple negotiations between the user and our sales personnel, the user quickly decided to place a new order for a ZJD-F-30 light oil coalescence separation oil filter, as the project had used our ZJD-F series light oil coalescence separation oil filter in 2018.

At the same time, a distributor company from Shanghai also visited our Chongqing Tongrui Oil Filter Company for on-site inspection. After visiting our company's production base and communicating with our technical personnel, they directly ordered a ZJD-F series light fuel filtration dehydration oil filter equipment.

This device is one of our non heating series products. It can be used not only for processing marine diesel, but also for filtering, dehydrating, and purifying diesel in oil depots to improve oil quality.At present, these devices have been produced, assembled, and debugged, and have been shipped as scheduled according to customer requirements.
