Why XICHENG
XICHENG designs, moulds, fabricates and exports waste gas treatment and ventilation equipment. Six reasons buyers stay with us.
In-House Moulding and Fabrication
Components up to 450 mm are injection-moulded in our own tooling; larger ducts, square sections and transitions are fabricated and welded in-house.
Engineered to Your Drawings
Scrubbers, towers and duct runs are built to client drawings, with process design support and engineers sent to site to guide installation.
Material Matched to the Duty
PP, PVC and FRP are quoted against the actual gas, temperature and moisture, so the wall, joint and gasket suit the stream they meet.
Capacity for Large and Repeat Orders
1,000+ staff and 40+ manufacturing facilities and offices, with the largest base rated at 5,000 sets of environmental equipment a year.
Export to 80+ Countries
Export packing, documentation and inspection support come as standard, and two factories in Vietnam serve Southeast Asian delivery.
R&D Backed by 50+ Patents
Joint research with Xi'an Jiaotong, Tongji and China University of Mining and Technology produced our permanent-magnet fans and valves.
