Falling Film Evaporator

Cold water flows evenly down the outer surface of the pillow-shaped plate in a thin film, thanks to the distribution trough at the top. Meanwhile, the refrigerant inside the plate enters the pillow-shaped structure and absorbs heat as it evaporates, effectively cooling and enabling ice formation. Compared to immersion-style ice-making, this method features a higher evaporation temperature and is more energy-efficient.

Equipment Advantages

The SPI wastewater heat exchanger is designed for applications such as liquid heating, cooling, and waste heat recovery. Featuring Xiehongtai's globally advanced laser-welded Pillow plate heat transfer technology, the heat transfer plates are arranged at specific intervals to form a compact plate bundle. On the wider external channels of the bundle, one fluid flows, while the narrower internal channels within the plates accommodate the other fluid, effectively achieving efficient heat exchange. The combination of Pillow plate heat transfer technology with a wide-channel design not only delivers an exceptionally high heat transfer coefficient but also endows the heat exchanger with remarkable advantages over conventional models—namely, superior resistance to high temperatures and pressures, excellent anti-fouling performance, ease of cleaning, and flexible assembly and disassembly capabilities.
