Product name: Air Defrosting Coolroom Evaporator Cold Room Outdoor Unit 23bar
EDG SERIES INDUSTRIAL DUAL-DISCHARGE GLYCOL UNIT COOLERS
1. Product description:
EDG series industrial air cooler adopts the structure of air inlet from the bottom and air outlet from the two sides., which are mainly used for cooling equipment in cold storage with glycol aqueous solution as the refrigerant. The low-temperature glycol aqueous solution circulates in the heat exchange tube of the cooling fan to absorb external heat, so as to achieve the purpose of reducing the storage temperature. EDG series of air coolers can be used in cold storage at 10℃, 0℃ and -18℃ respectively
This series of products have the following characteristics:
● Casing:high quality galvanized steel with silver powder coating (RAL7001) , it has strong anti-corrosion property; The outer water plate adopt hinge structure, convenient and quick operation.
● Evaporator end plate adopts aluminum plate, effectively protect copper tube, reduce weight.
● Double water plate design: the outer water plate adopts angular structure, smooth drainage, no drainage dead angle; The inner water tray adopts the flume structure of aluminum plate. The condensed water or defrosted water is directly discharged into the outlet of the outer water tray through the inner water tray.
● Coil:copper pipe φ15, tube spacing 50×50 square arrangement, heat transfer area is large, heat transfer temperature difference is small, fin frosting speed is slow.
● Corrugated aluminum fins with hydrophilic film, fin spacing of 4.0 , 6.0 and 9.0mm to meet the different temperature requirements of cold storage.
● Fan: high-power external rotor fan of blower, operating temperature -30℃~60℃; Fan specifications φ450,φ500, the formation of different specifications of the product series, users have more choices.
● Defrosting:standard electric heating defrosting, stainless steel heating pipe are distributed on the coil tube fin and inner water plate, has a good defrosting effect.
● IP65 grade waterproof junction box and waterproof connector, the fan and heating pipe adopt independent wire box ,with better waterproof effect, high reliability.
● Strict factory pressure test, test pressure 23bar.

5.How to select correct evaparator:
Generally,Choose evaporator capacity=cold room cooling capacity *1.15
1.When the cold room temperature is around 0℃, select 4.5mm as fin space.
Evaporator choose=1.0*Q0
2.When the cold room temperature is around -18℃, select 6mm as fin space.
Evaparator choose=1.1*Q0
3.When the cold room temperature is around -25℃, select 9mm as fin space.
Evaparator choose=1.27*Q0
Remarks: The water defrost and hot gas defrost type are also optional.
