The semi-welded technology offers distinct advantages over traditional gasketed plate heat exchangers. By welding the plates in pairs, the milk channel is completely sealed, eliminating the risk of cross-contamination between milk and service fluid (e.g., hot water or steam). This design also withstands higher pressures and temperatures, making it suitable for continuous pasteurization at 72–85°C and flash sterilization at 130°C. The sanitary tri-clamp connections align with 3-A Sanitary Standards and are widely accepted in dairy plants for their ease of disassembly and cleaning-in-place (CIP) compatibility.
Our heat exchangers undergo rigorous quality control at every stage, from raw material inspection to final pressure testing. Each unit is hydrostatically tested at 1.3 times the design pressure to ensure leak-free operation. The company holds multiple certifications including HACCP, ISO9000, ISO14000, and OHSAS18001, reflecting our commitment to food safety, quality management, and environmental responsibility. With an annual export value exceeding US$10 million, we have supplied thousands of units to dairy processors across 50+ countries.
