Our company provides a limited quality warranty for the industrial water purification equipment sold, to ensure that under normal usage and maintenance conditions, the equipment's performance meets the technical specifications.

During the warranty period, for equipment failures caused by product design, materials, or manufacturing workmanship, our company will be responsible for repairing or replacing the faulty components. The service method can be remote guidance or on-site repair, depending on the specific fault situation.

Warranty periods vary for different products; please consult customer service for details.

For failures caused by the following circumstances, our company will charge repair service fees and parts costs even during the warranty period:

1. The customer disassembles or modifies the equipment without prior written permission from our company.

2. The customer fails to operate the equipment according to the User Manual, for example, running it without water, exceeding pressure limits, or having feed water quality that seriously exceeds standards, thereby causing membrane element fouling or pump damage.

3. The customer uses chemicals not specified by our company for chemical cleaning, resulting in corrosion of membrane elements and piping.

4. Failures caused by force majeure events, such as earthquakes, floods, fires, or abnormal power grid fluctuations.

5. Issues resulting from normal wear and tear: including the natural decline in membrane element salt rejection and pressure gauge calibration.
