ColdCrate at Energlo Diesel 

Refrigeration Principle: 

High temperature & high-pressure refrigerant gas goes into the air-cooled condenser after compressed. The gas condenses in the air-cooled condenser, changes to liquid,passes by the filter which removes water and impurity,

which then passes capillary tubes which reduces pressure.

Later, the low temperature, low pressure liquid flows

through evapoator and evaprates / absorbs heat,

reducing the temperature in the box. 

Temp -18* F
