About Zhongxin
An equipment manufacturer, not just a trader — design, machining, testing and support under one roof.
Jiangyin Zhongxin Machinery & Electrical Co., Ltd.
Founded in 2014, we are an integrated manufacturer of aeration and aquaculture equipment — Roots blowers, microporous aeration tubes and discs, floating aerators and galvanized canvas fish ponds.
We design, machine, test and ship complete systems, and back them with installation schemes and after-sales support. Our aim is simple: equipment that raises dissolved oxygen at the bottom of the pond, raises stocking density, and lowers the customer's energy bill.
12 years of hands-on experience in aquaculture aeration systems — high-density shrimp farming, hatchery and RAS projects.
