With regard to CKRS-X3.5WF/ALA ,when system found ice or frost ,the four way valve will change to cool function automatically,so defrost the system.
 
Our patented system use a Solenid Valve which is installed on the compressor vent pipe to defrost the bottom of condendor,and then system changes to normal defrost way(by four way valves).
 
Have your customers confirm the 20GP container order?

Switzerland  Zurich   21.10.2010   at 7.30 in the  morning,  temperatures minus 3C
The bottom plate completely frozen
After deicing the unit, top and bottom plate are removed to see what happening.   The fan run very slow and the unit start icing up from the bottom. Icing of the bottom plate first.
The Icing is from the bottom and up wile the fan is moving on low speed. 
When the condenser is 3/4 frozen from the bottom is still liquid gas in the accumulator so its no shortage
It looks like liquid gas from the bottom part, while top part get nothing.
