Product name: Waterproof IP65 Commercial Coolroom Evaporator Air
Cooler For Cold Storage
EHG SERIES COMMERCIAL CELLING GLYCOL UNIT COOLERS
1. Product description:
The EHG series commercial ethylene glycol cooler developed by our
company adopts φ 12 copper tubes, cold storage cooling equipment
with glycol aqueous solution as refrigerant. The EHG series of air
coolers can be used in cold storage at 10℃, 0℃ and -18℃
respectively, mainly for cold storage with medium and small cooling
capacity.
This series of products have the following characteristics:
● Casing: high quality galvanized steel plate with silver powder
coating (RAL7001), with strong corrosion resistance; The two side
plates and the outer water plate adopt the hinged structure, which
is convenient and fast to operate.
● 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.
● The long air duct design with integral stretch arc has good air
flow effect.
● For fan with diameter of 500, there are floor support feet for
easy installation.
● Coil:copper pipe φ12, spacing 38.1×33, triangle arrangement, heat
transfer efficiency is high.
● Corrugated aluminum fins with hydrophilic film, fin spacing of
4.0 and 6.0mm to meet the different temperature requirements of
cold storage.
● Fan: high-power external rotor fan, operating temperature
-30℃~60℃; Fan specifications φ350,φ400,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.
