Yuyan Introduction
Changzhou Yuyan Refrigeration Equipment Co., Ltd. is a leading cold storage plant and the overall energy efficiency solutions provider and one of the largest energy-saving manufacturers of cold storage panel. The cold storage panel is using polyurethane materials for the inner and the surface of panel using pre-painted galvanized steel sheet , 304 stainless steel sheet or aluminum embossed stucco sheet which can effectively reduce the heat generated due to the temperature difference between inside & outside and to achieve maximum efficiency refrigeration system. The scientific connecting method for the panel is by tongue-and-groove dry joint by cam lock which will have the good sealing performance and easy accessibility to ensure the excellent aesthetics for the cold storage installation.
The evaporators of DL, DD and DJ series are made by copper tube and punching of forming a second flange of aluminum fins with high heat transfer efficiency, and the coolers used are anti-moisture, low temperature, big wind, low noise, smooth operation and reliable. The stainless steel tubes used for the electrical hot-melt frost system whose fin heating tube is directly into the inside, and its defrosting time is short and effective; The shell is used with high-quality steel plates and the spray process is corrosion resistance, appearance smooth, beautiful, generos.
DL, DD, and DJ series of roof suspended air coolers can match with compressor condensing units with different cooling capacities and can be used in cold storage houses which are in different temperature being the refrigeration equipments. DL series are suitable for the storage of temperature of 0° C. The cooling storage can be available for fruits and vegetables, eggs and other DD series apply to the cold storage whose temperature around-18° C for the storage of meat, fish and other frozen foods; DJ series are suitable for -23° C to freeze the meat, aquatic products.
