Hanertech's solid heat exchange technology consists of a series of parallel-arranged pillow plates and corrugated plates. The pillow plates and corrugated plates each form individual heat exchange units, and by stacking multiple heat exchange units, a significantly larger heat transfer area can be achieved.
In a pillow-plate heat exchanger, the hot medium flows through the gap between the pillow plates and corrugated plates, transferring heat to the cold medium on the opposite side. The space between the pillow plates and corrugated plates forms separate flow channels, allowing the hot and cold media to move independently—each following its own distinct path—thereby enabling the cooling, heating, or drying of bulk solids.

Waste Heat Recovery and Utilization
Hanertech has independently developed the Pillowplate, a unique pillow-shaped heat transfer plate, utilizing advanced laser welding technology and integrated bulging molding. All components are crafted from premium stainless steel materials or higher-grade alloys. Leveraging our proprietary Pillowplate technology, we have created innovative products such as plate-type air-to-water heat exchangers and plate-type air-to-air heat exchangers, along with a comprehensive range of waste heat recovery systems. These systems cover waste heat recovery across solid, liquid, and gaseous media, enabling the full-scale reuse of heat—from high-temperature to medium- and low-temperature applications—tailored to meet diverse customer needs. Applications include winter heating, preheating boiler condensate, summer cooling, and even waste heat-to-power generation.
Hanertech has independently developed the Pillowplate, a pillow-shaped heat transfer plate that utilizes laser welding technology and is formed through an integrated expansion process—all crafted from materials equal to or superior to stainless steel. Leveraging our proprietary pillow-shaped heat transfer plate technology, we offer both plate-type air-to-water heat exchangers and plate-type air-to-air heat exchangers.
Not only have we integrated a dedicated anti-fogging system into our product designs (patent application pending: Patent No. ZL 2021 2 1696521.7), but this system has already demonstrated remarkable performance in real-world applications, earning high praise and satisfaction from our customers!
Meanwhile, Hanertech continues to innovate by further enhancing our anti-fogging system—this time by incorporating waste heat recovery into the design, creating an advanced anti-fogging system (patent application pending: Patent No. ZL 2021 2 1865550.1). This cutting-edge solution not only effectively prevents fogging but also captures low-temperature waste heat, repurposing it to generate hot water and provide cooling. In doing so, we’re pushing the boundaries of energy efficiency and environmental sustainability even further!
Hanertech's static melt crystallizer is a device that uses vertically arranged special-shaped plates, employing an internally circulating heat transfer medium (HTM) to either heat or cool the system. Steel plates are suspended within the molten feed material. As the stagnant melt cools slowly below the freezing point of the HTM, crystals begin to grow on the plates, enabling the separation and purification of the target substance.
Cooling: The material enters the heat exchanger from the top, filling the interior completely up to the feed hopper, ensuring the material submerges the heat transfer module. At this point, cooling water flows into the module plates from the bottom and exits through the upper section of the heat exchanger. Meanwhile, the discharge rate of the feeder at the top of the feed hopper is adjusted according to the incoming material volume, maintaining a consistent material level within the hopper.
The material in operation flows uniformly and as a whole between the heat-transfer module plates, achieving cooling by means of indirect heat exchange with the cooling water inside the heat-transfer plates.

The SGG gas-to-gas heat exchanger utilizes Pillow plate heat transfer elements arranged at specific intervals. Inside the plates are clean gas channels, while the outer surfaces accommodate the process gas (flue gas) flow. The spacing between the heat transfer plates can be flexibly designed and adjusted according to the operating conditions. Combined with a wide-channel design, the Pillow plate heat transfer elements not only deliver exceptionally high heat transfer efficiency but also feature low pressure drop, excellent resistance to high temperatures and pressures, durability against dust accumulation, and ease of cleaning.
Significantly superior technical features compared to conventional heat exchangers.

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.
