Stainless Steel Tank & Vessel Manufacturing

RITAI sanitary tube-in-tube heat exchanger is specially designed for cooling processes of injection water (WFI) with a flow rate less than 1500 Lph. This heat exchange consists of two tubes, an inner and an outer coiled together, which ensures rapid cooling, minimal maintenance, and no risk of cross-contamination between the product and working fluids.

• The entire heat exchanger is made up of three layers of seamless steel tubes, formed in one piece without any risk of leakage (no internal welding). It is manufactured as an integral structure. There is a disturbance device between the two tubes on the cooling medium side to enhance the heat transfer effect. On the product side, there are no cervices or dead corners.
• The product flows through the central channel, while the cooling medium flows through the inner and outer layers of the heat exchanger. The three-layer tubes are bent into a U-shaped design, allowing for the elimination of any thermal expansion generated during heating, cooling, or even steam sterilization with large temperature differentials. The counter-current flow design ensures optimal heat transfer efficiency and a greater cooling range.
• RITAI sanitary tube-in-tube heat exchanger can be sold as a single unit or as a complete modular system, with the modular option being easier to install and use. The module consists of a tube-in-tube heat exchanger, an outer casing, valve assembly, and Pitot tube interface. Our specially customized Pitot tube interface is used for connecting the heat exchanger to the main pipeline system.
