SIGMA Process Equipment

Who We Are

SIGMA Process Equipment is a specialist dealer and exporter of used industrial chemical and process equipment, operating from China. Our stock is sourced from China's largest concentration of surplus industrial plant — a network of decommissioned chemical plants, pharmaceutical facilities, food processing operations, and engineering yards that generates a continuous flow of inspected, export-ready machinery.

Buyers come to us because the Chinese surplus market holds equipment types and brands that are difficult to find elsewhere: glass-lined reactors, large-format plate and frame filter presses, multi-effect falling film evaporators, industrial disc stack centrifuges, and more — often available at a fraction of the cost of new fabrication, with lead times measured in weeks rather than months.

QUALITY IS POWER

Our operating principle is straightforward: a used equipment transaction only works long-term if the buyer receives machinery that performs as represented. Every unit we list has been mechanically inspected before sale. Inspection findings, condition photos, and available service records are shared with every quote — buyers see the real condition of the equipment before they commit.

We do not ship equipment with unknown mechanical history or undisclosed defects. If a unit has wear, we document it. If something cannot be verified, we say so. Buyers can then make an informed decision, request an independent inspection, or ask for refurbishment before dispatch.

Export & Logistics

SIGMA handles the complete export process: inspection documentation, export packing (wooden crates, seaworthy packaging, moisture protection), customs clearance paperwork, certificate of origin, and freight booking to any port worldwide. We work under all standard Incoterms — EXW, FOB, CFR, CIF, DAP — depending on the buyer's preference and destination.

Shipments go to chemical plants, engineering companies, and equipment dealers in Europe, Southeast Asia, the Middle East, Africa, South America, and beyond. Our team handles export formalities daily and understands the documentation requirements for used industrial machinery in most major import markets.

How to Buy

The process is simple: submit a request for quotation describing the equipment type, capacity, and any specific requirements. We check current stock, pull condition photos, and respond within 24 hours. If a unit matches your requirement, we issue a detailed quote with photos, inspection notes, and logistics estimate. Payment terms and shipping are agreed before any unit is reserved.
