Our History

Xiangshui Delkang Refrigeration Equipment Co., Ltd., formerly part of the Huizhong Group, is a restructured enterprise and one of the leading manufacturers of heat exchangers for air conditioning systems in China. Located in Xiangshui County, near Lianyungang, Jiangsu Province (the hometown of the Monkey King's Flower and Fruit Mountain), the company shifted its focus to producing heat exchangers for central air conditioning systems after 2000, following the trend of large air conditioning companies producing their own major components. Following restructuring in 2006, Xiangshui County Derkang Refrigeration Equipment Co., Ltd. was established, enhancing the company's autonomy and leading to the development of various specifications of heat exchangers for multiple industries. Since entering the market, its products have gained the trust of numerous enterprises and established strong cooperative relationships with many domestic companies.

Our company is a refrigeration component manufacturer specializing in various tube-and-fin heat exchangers. Our products use copper and aluminum as the main raw materials and are manufactured through advanced processes. They are essential components of energy exchange equipment. Specific types include: A. Copper Tube Aluminum Fin Type: This heat exchanger uses copper tubes with diameters of 9.52/15.88/7 mm and corrugated or double-bridged aluminum fins. Through rigorous mechanical expansion, it ensures tight contact between the aluminum fin hole walls and the copper tube, preventing the effects of thermal expansion and contraction, thus achieving stable and continuous heat exchange. Its efficiency is 1.2-1.3 times higher than ordinary heat exchangers. This product is available in flat, L-shaped, U-shaped, G-shaped, and O-shaped shapes. It is a customized, high-efficiency condenser and evaporator for various air conditioning units, condensing units, and heat pump units, enabling heat exchange between hot/cold water and air, and between refrigerant and air. B. Copper Tube/Finned Type: This heat exchanger uses copper tubes with diameters of 9.52/15.88/7 mm, employing corrugated fins or double-bridged open-window copper foil, manufactured according to standards through rigorous mechanical expansion. Its products are characterized by strict material selection, meticulous manufacturing, stable performance and quality, and corrosion resistance. Each unit undergoes rigorous testing to ensure high pressure resistance and zero leakage. It is an essential component of air conditioning or heat exchange systems in marine, chemical, and textile industries. Target Market: Our company's heat exchangers, thanks to their superior product quality, strong technical support, reasonable prices, and excellent corporate reputation, have successfully established cooperative relationships with numerous enterprises across various domestic industries.
