Maintance and Service
4-Year Warranty – Every radiator is backed by a 4-year warranty, ensuring long-term reliability and peace of mind.
How We Produce
SINRUI's Vacuum Brazing Core Technology – At SINRUI, we operate dedicated vacuum brazing furnaces that fuse the aluminum plate-fin core into a single, leak-free unit. This proprietary process, tightly controlled in our own facility, ensures optimal heat transfer and structural integrity for every radiator.
Backed by ISO 9001 certified quality management, every radiator must pass a series of rigorous validations—including leak, pressure, and thermal cycling tests—before approval. This end-to-end control guarantees that we deliver products with outstanding durability, stable performance, and consistent cooling reliability, batch after batch.
