How We Produce
The manufacturing of every SINRUI radiator involves meticulous process oversight in our advanced workshop. It begins with accurate copper tube formation and fin attachment, followed by solid-frame welding, all performed according to international norms to assure resilience and efficiency.
Our ISO 9001 certification underscores this rigor: each radiator is subjected to final leak, pressure, and thermal assessments before leaving the plant. We therefore promise our customers a product distinguished by its uniform quality, exceptional lifespan, and steadfast heat dissipation.
