Series electric defrost air cooler is a kind of cooling and cooling equipment in the cold storage used in the refrigeration unit, according to the applicable temperature, divided into DL, DD, DJ three series, can be applied to different storage temperatures, DL type air cooler is mainly suitable for about 0ºC fresh storage, DD type air cooler is mainly suitable for -18ºC cold storage, DJ type air cooler is mainly suitable for -25 "C below the freezer.
CHARACTERISTIC
Features:
It is specially designed for refrigeration, freezing and preservation, prolonging the storage cycle of products and ensuring product quality to the greatest extent;
The shape and structure are compact, and do 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 an efficient heat exchange effect: the coil is tested for air tightness under 2.8MPa air pressure to ensure the quality characteristics of high air tightness when the product leaves the factory; Motor: Conventional grille type, outer rotor 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 of the elbow parts at both ends is less;
The dispenser assembly selects the best scheme through theoretical calculation and practical testing to maximize the uniformity of dispensing. The electrodefrost type air cooler is adopted, with an aluminum plate at the bottom, to improve the effect of forced heat exchange;
The heating wire is in close contact with the aluminum plate and heated, so that the water tray is more evenly frosted;
Water Flushing Series Air Cooler, Unilateral Air Outlet, DL, DD, DJ three series of products have a complete chain and wide storage temperature coverage: -35~20ºC, suitable for various industrial cold storage.
CHARACTERISTIC
Features:
Fan diameter ø500~710, three-phase voltage;
Baffles are added before and after the coil to avoid frost water splashing 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 to 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 offices for details.
enclosure
It is made of high-quality galvanized steel sheet and has very good corrosion resistance. The tuyere is stretched into a bell by the fan baseplate, 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 exchange 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 integrated hot-dip galvanized, which has strong corrosion resistance and longer service life. The fins and heat exchanger tubes are treated by a monolithic hot-dip galvanizing process with a galvanizing thickness
0.06-0.10mm, 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 adopted 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.
