Our company’s surface-type coolers are among the core heat-exchange devices in air-conditioning and ventilation systems. They are primarily used to cool and dehumidify air, and can also be switched to hot-water or steam mode during winter to provide air heating. By utilizing a refrigerant (such as chilled water, refrigerant, or brine) or a heat-transfer medium (such as hot water or steam) flowing inside the tubes, these units facilitate forced‑convection heat exchange with the air flowing outside the tubes, thereby regulating air temperature and humidity. As the central heat-exchange components of chiller units, fresh-air handling units, fan coil units, and other equipment, they offer high heat-exchange efficiency, flexible installation, and broad compatibility.
Our company’s heat pipe heat exchangers are energy‑saving heat exchange devices that leverage the phase‑change heat transfer principle of heat pipes to achieve highly efficient heat transfer. With heat pipes as the core heat‑transfer elements, they enable rapid heat transfer and recovery without direct contact between the hot and cold fluids, making them one of the key pieces of equipment for industrial waste‑heat recovery, HVAC energy conservation, and process temperature control applications.
Our company’s heat-pipe heat‑exchanger cabinet is an integrated, energy‑saving heat‑exchange device that incorporates a heat‑pipe heat exchanger within a compact enclosure. With the heat pipe as its core heat‑transfer element, it enables complete separation of hot and cold fluids while delivering highly efficient heat exchange. It serves as a modular solution for industrial waste‑heat recovery, HVAC energy conservation, and process temperature‑control applications. The unit integrates the heat‑pipe heat‑exchanger core, airflow channels, insulated cabinet, and mounting interfaces into a single, self‑contained assembly. It requires no complex piping infrastructure, offers easy installation and stable operation, and can recover heat even under harsh conditions such as high temperatures, dusty environments, or corrosive atmospheres. Featuring high heat‑transfer efficiency, zero cross‑contamination between hot and cold streams, simple maintenance, and modular adaptability, it is widely used in industrial flue‑gas waste‑heat recovery, fresh‑air energy recovery, and energy‑efficient upgrades to air‑conditioning systems.
Our company manufactures duct-type heaters—also known as air‑duct or shell‑and‑tube electric heaters—which are installed within ventilation ducts or fluid‑transport pipelines. Powered by electricity, these devices heat the gases or liquids flowing through them, with their core component being finned electric heating tubes that enable rapid temperature rise of the medium. These heaters feature a compact design and high thermal efficiency, making them suitable for rectangular ducts, circular pipes, or industrial fluid lines. They can heat gaseous media such as air and flue gas, as well as liquid media like water and oil, while offering precise temperature control, flexible installation, and reliable safety. As a result, they are widely used in HVAC systems, drying processes, industrial fluid heating, exhaust‑gas treatment, and other applications.
