The special air cooler for quick-freezing storage adopts copper tube and aluminum sheet sprayed shell or 304 stainless steel shell, and the high-power internal rotor axial motor is suitable for short-term rapid freezing storage temperature -35°C--45°C. Water cream, hot fluoride cream or electrochemical cream can be used;
For refrigeration units, according to the applicable temperature, it is divided into three series: DL, DD, DJ, which can be applied to different storage temperatures, DL type air cooler is mainly suitable for fresh storage around 0ºC, DD type air cooler is mainly suitable for -18ºC cold storage, DJ type air cooler is mainly suitable for freezers below -25"C.
peculiarity
Peculiarity:
It is specially designed for refrigeration, freezing and preservation, prolonging the storage cycle of products and ensuring product quality to the greatest extent;
Compact shape and structure, does not occupy the usable area of cold storage;
The copper tube adopts a mechanical expansion tube to make the fins and the copper tube fit closely to ensure efficient heat exchange effect: the coil is tested for air tightness at 2.8MPa air pressure to ensure the quality characteristics of high air tightness when the product leaves the factory; Motor: Conventional Grid Type, Outer Rotor Air Duct Type, Outer Rotor Panel Type, Inner Rotor Axial Flow Type:
The length of the stainless steel heating wire is much larger than the length of the coil core, so that the frost accumulation at the elbow parts at both ends is less;
Dispenser components select the best solution through theoretical calculations and practical tests to maximize the uniformity of dispensing. The electric defrost air cooler is adopted, and there is an aluminum plate at the bottom to improve the forced heat exchange effect;
The heating wire is in close contact with the aluminum plate and heated, so that the water pan is more evenly sanded;
Flush series air cooler, unilateral air outlet, DL, DD, DJ three series of products have complete chains, wide storage temperature coverage: -35~20ºC, suitable for all kinds of industrial cold storage.
peculiarity
Peculiarity:
Fan diameter ø500~710, three-phase voltage;
Baffles are installed before and after the coil to avoid frost splashing on the motor shell or dripping on the motor shell and burning the motor;
The depth of the water tray is reasonable to prevent overflow when the water volume is too large;
Frost at both ends of the coil, remove the frost layer to avoid freezing;
The drip tray above the coil is evenly distributed, and the water outlet hole is located above the copper pipe to avoid water splashing;
Non-standard products can be customized according to customer requirements to meet special requirements, please consult our distribution office for details.
enclosure
It is made of high-quality galvanized steel sheet with very good corrosion resistance. The tuyere is stretched into a bell shape by the fan bottom plate, which not only increases the rigidity of the tuyere, but also ensures smooth airflow and small resistance loss.
coil
Aluminum tubes and aluminum fins are characterized by light weight and fast thermal conduction. The expansion connection between the fin and the heat exchanger tube adopts imported special equipment and is in close contact, so as to achieve low thermal contact resistance and high heat exchange efficiency.
The steel pipe and steel fin are one-piece hot-dip galvanized, which has strong corrosion resistance and longer service life. The fins and heat exchanger tubes are galvanized thick
The degree is 0.06-0.10mm monolithic hot-dip galvanizing process, so they are composed of integral heat exchangers. In addition, the design in the tube is optimized, the resistance is reduced, and the heat transfer efficiency is very high.
The combination of constant fin spacing and variable fin spacing is used to better improve the heat transfer efficiency of the air cooler in various environments. The coil frame is made of hot-dip galvanized integral galvanizing, so it has high strength and good corrosion resistance.
The sheets have a large size and wavy integrity, which achieves high heat exchange efficiency and also facilitates hygienic handling. The aluminum fins are in the form of fins, combining a stretched and elevated neck ring with constant fin spacing; The steel fins adopt a special crown structure with constant spacing to ensure the accurate positioning of the fins.
Axial fans and motors
The screen protection axial fan is characterized by high efficiency, wide range of air volume and air pressure
, stable operation and low noise. The blades of the fan are made of die-cast aluminum alloy so that light weight and good corrosion resistance are achieved. The new blade design makes for better aerodynamics. The fan motor is IP55 rated and can be used in a temperature range of -40ºC-40ºC.
Cooling water tank and water tray
The cooling water tank and water tray are made of high-quality galvanized steel sheet with very good corrosion resistance. The cooling tank designed by mesh water spray method has the characteristics of uniform water spray, no blind area, fast defrosting speed and low water consumption. The water tray is removable, so it is easy to clean and ensure hygiene. The shielding plate between the cooling water tank and the water tray effectively prevents water from splashing outside.
For refrigeration units, according to the applicable temperature, it is divided into three series: DL, DD, DJ, which can be applied to different storage temperatures, DL type air cooler is mainly suitable for fresh storage around 0ºC, DD type air cooler is mainly suitable for -18ºC cold storage, DJ type air cooler is mainly suitable for freezers below -25"C.
