Manufacturing & Factory

At our 64 hectare (640,000 m²) manufacturing base in Nantong (1180 Jianghai Avenue & No. 155 Renmin West Road, Qidong), 1,800+ staff across five factories build our drums, belts, coils, pressure vessels, and PIR panels under one roof.

Integrated Manufacturing, One Quality System

Every major step happens under one quality system. We handle steel cutting, ASME skid assembly, German Hennecke PIR foaming, coil building, PLC wiring, and full factory test runs in our own plants.

  • Steel Fabrication

    Uses fiber laser cutters, CNC punches, automated benders, and surface treatment booths for SUS304 and SUS316 stainless steel.

  • Refrigeration Assembly

    Builds screw and piston compressor skids, condensers, and ASME or PED pressure vessels using automated welding and X-ray checks.

  • PIR Panel Foaming

    Runs three German Hennecke PIR panel lines, making FM approved cold storage and freezer panels from 50 to 250 mm thick.

  • Evaporator Production

    Builds blast coils, unit coolers, and condensers with hydraulic tube expansion and 2 to 12 mm fin spacing, plus aluminum contact plates.

  • Electrical & Controls

    Builds and tests Siemens and Allen-Bradley PLC cabinets, touchscreens, VFD drives, and remote gateways with 100% wiring checks.

  • FAT & System Testing

    Every spiral drum, drive, control cabinet, and compressor skid passes test runs and pressure checks in our CNAS lab before shipping.

Key Equipment

Manufacturing Technology

Modern automated tools cover every step from raw steel cutting to final system tests.

  • Laser Cutting Centers

    Automated laser cutters shape stainless steel frames, drum parts, and sheet metal with high accuracy.

  • CNC Punch Machines

    CNC punch and forming centers keep air baffles and wall panels consistent across large runs.

  • Sheet Metal Lines

    Automated bending, roll forming, and pickling lines build clean stainless steel housings with minimal welds.

  • Hennecke PIR Lines

    Three German Hennecke foaming lines make closed cell (≥93%) PIR panels over 12 meters long.

  • Auto Welding Equipment

    Automated orbital, plasma, and TIG welders create leak tight joints on coil headers, aluminum plates, and ASME vessels.

  • Evaporator Lines

    Dedicated fin stamping and tube expansion lines build NH3, CO2, and HFC heat exchangers in a 38,000 m² plant.

  • Surface Treatment

    Bead blasting, pickling, passivation, and powder coating lines protect steel frames and coils in wet washdown rooms.

  • Test Center

    Our CNAS lab tests freezer airflow, coil output, and compressor skid performance at design temperatures.
