Steel Fabrication
Uses fiber laser cutters, CNC punches, automated benders, and surface treatment booths for SUS304 and SUS316 stainless steel.
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.
Manufacturing Shops
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.
Uses fiber laser cutters, CNC punches, automated benders, and surface treatment booths for SUS304 and SUS316 stainless steel.
Builds screw and piston compressor skids, condensers, and ASME or PED pressure vessels using automated welding and X-ray checks.
Runs three German Hennecke PIR panel lines, making FM approved cold storage and freezer panels from 50 to 250 mm thick.
Builds blast coils, unit coolers, and condensers with hydraulic tube expansion and 2 to 12 mm fin spacing, plus aluminum contact plates.
Builds and tests Siemens and Allen-Bradley PLC cabinets, touchscreens, VFD drives, and remote gateways with 100% wiring checks.
Every spiral drum, drive, control cabinet, and compressor skid passes test runs and pressure checks in our CNAS lab before shipping.
Key Equipment
Modern automated tools cover every step from raw steel cutting to final system tests.

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

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

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

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

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

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

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

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