Our Service
During the pre-sales phase, we tailor technical solutions to the client's specific needs - such as on-site grain silo conditions and processing capacity - while providing expert guidance on product selection to ensure the right equipment is matched to the application. During the sales process, we monitor production progress in real-time and provide a complete technical package - including installation drawings and operating manuals - to ensure the project proceeds smoothly. We offer a one-year warranty on the entire unit; the equipment utilizes internationally standardized parts, allowing for local procurement of spares in overseas markets. For international projects, we primarily provide remote video-based guidance for commissioning and maintenance; should on-site service by our technicians be required, the client is responsible for associated travel expenses. Beyond the warranty period, we continue to provide long-term technical support - including spare parts supply and remote troubleshooting - upholding our commitment to ongoing service and lifetime warranty coverage.
