Your Long - term Partner: Haina's Global Service Commitment

Buying emission control equipment should not be a "one - and - done" gamble.

That's why Haina offers a comprehensive global after - sales service framework to give you peace of mind:
·12 - hour emergency response: Dispatch on - site engineers within 12 hours after a fault report (for domestic customers; overseas through local partners).
·Semi - annual follow - up visits: Free inspections twice a year, covering motors, valves, automation systems, and structural integrity.
·Extended warranty options:
Multi - tube dust collectors: 5 years
Bag dust collectors: 2 years (including filter bags)
SCR catalysts: 1 - 3 years, depending on the installation location
We also offer remote diagnostic support, spare parts inventory planning, and operator training programs—available in English, Spanish, and Portuguese.
·A customer from Peru shared: "After two years of operation, their team still follows up regularly. They feel more like partners than just suppliers."
Because clean air is not a one - time purchase—it is a lifetime commitment.
