Why buyers stay
Every unit ships with a factory acceptance test record, material certificates and welding documentation. When a damper must seal or a deaerator must hit its oxygen specification, you have the test data before the equipment leaves our works.
How it works
No account managers between you and the engineers who size, fabricate and test your equipment.
Duct dimensions, media and temperature, or drawings of the existing installation. Photos of the site help us match flange positions.
Sizing calculation, sealing concept and actuator recommendation. Itemized quotation within 24 working hours.
GA and detail drawings issued for your sign-off before any steel is cut — revisions included at no cost.
Cutting, welding, machining and assembly, then leakage and torque testing witnessed by you or SGS/BV.
Seaworthy wooden cases with export documentation, plus installation supervision and commissioning guidance on site.

Explore →★★★★★
“The desulfurization dampers passed the leakage witness test first time, and the sealing-air package arrived pre-assembled. Our shutdown went exactly to schedule.”
★★★★★
“They dimensioned the slide gate valves from our site templates when the original supplier had closed. Fit was perfect on both units, and commissioning took a single shift.”
★★★★★
“Deaerator oxygen content has stayed below 0.03 mg/L since commissioning. Paperwork, spares and after-sales response are all what we expected from a qualified supplier.”
