In terms of production management, TENESUN strictly adheres to the ISO9001 quality management system standards, establishing a comprehensive quality control mechanism covering the entire process from raw material procurement, production and processing, and finished product inspection to warehousing and delivery.The company has developed a significant technological advantage, particularly in the production and processing stage. The flexible air-source heat pump water heater production line established by the company is one of the earliest advanced production lines in the industry to achieve multi-category compatible production. It utilizes refined production processes and automated production equipment, with intelligent control of key processes. For example, the assembly of core components uses precise positioning technology to ensure assembly accuracy is controlled within millimeters.Simultaneously, a digital production management system has been introduced to achieve real-time monitoring and data traceability of the production process, allowing for quick identification and resolution of potential problems during production.


Operating Instructions
