Green Low-Temperature Purification

Hanertech develops and designs melt crystallization process technology, offering customized standalone equipment, integrated skid-mounted units, or on-site installation systems.
Melt crystallization is a method for separating and purifying substances based on their differing melting points, making it an energy-efficient, clean separation process for organic compounds. It demonstrates high efficiency in isolating special systems—such as hydrocarbons with closely matched boiling points, structural isomers, and heat-sensitive materials—while the production of ultra-pure substances stands out as a unique advantage of melt crystallization.

Our approach of static stepwise crystallization is a novel method for separation and purification. By using specially designed crystallization plates and a self-developed temperature-control unit that precisely regulates the medium temperature within the plates, we enable the target substance to gradually transition from a saturated state into an oversaturated one, prompting the desired compound to crystallize and precipitate out—eventually forming a continuous crystalline layer on the plate surface. Meanwhile, melt crystallization yields high-purity products through a three-step process: cooling-induced crystallization, warming-induced sweating, and subsequent heating to achieve complete melting.

Solid Heat Exchange

Solid Heat Exchange

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

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.
Flue Gas Decolorization

Flue Gas Decolorization

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!
