Product Description

DJ-3.4/20 DJ Type electric iron body ammonia air cooler without water for cold room refrigeration unit

 

Introduction

 

Model D Series Air cooler/Cooling Fan/ Evaporator is a type of cooling equipment applied to vrious of refrigeratories like frozing, storing and freshing food. Model D series have the three types: DL, DD, DJ, which can meet different requirement on temperature. Model DL applies to 0 degree freshness storehouse. Model DD applies to -18 degree cold storage. Model DJ applies to -25 degree quick-frozen storage.

 

Feature

 

1. With reasonable structre, symmetrical forming frosting, highly-effective performance on heat transfer.

2. Assembled with high quality fan and motor, to make sure the low noise, big air volume and stable operation.

3. All the air coolers are tested under 2.5MP pressure, so to make sure they are in high air tightness.

 

 

RFJ  air cooled evaporator are suitable for high,middle,low temprature(+10°C- -35°C)
1.light in weight,convenient intallation,compact structure,Rapid temperature falling,long preservation time.
2.efficient fins, more evaporation area.
3.mechanical tube expanding,tight connection between fins and copper pipe to increase heat exchange efficiency.
4.bright type copper tube thickness:0.35mm,silverbrazing for elbow.
5.motor:efficient,low power-consuming,strong windy,Wide-range, low noise,long service time.
6.over 2.6MPa pneumatic test permition,reasonable design, Power conservation by 25%.
7.cold-rolled steel plate for shell,phosphating static spraying technique,pleasing shape,rustproof.
8.Defrost heat performance: 8 hours defrost cycle.

 

DL DD DJ series for your choice

 

DL : High temperature

DD : Medium temperature

DJ : Low temperature
