In the Transport Refrigeration Industry, converting to HCFC or CFC
refrigerants created a lot of problems and expenses for equipment and its
owners. The compressor oil had to be changed to a specific type. Rubber
hoses, pressure switches, driers, and Ids had to be changed also. The
troubles began there and don't stop, there are more coming. Before I
discovered the HC refrigerants, I was very busy replacing compressors,
rubber hoses, blown manifold and head gaskets, and resoldering melted
joints, all due to extreme heat and pressures created by these synthetic
HCFC/CFC refrigerants.
When I encounter a unit that has lost its charge, the system is dry
nitrogen tested, any leaks are repaired, the compressor oil is checked,
the drier changed, and the system is evacuated and recharged with HC-12a/134+
or HC-22a/502a with less than half the original charge. The unit is then test
operated and has lower pressures, lower head temperatures, better compressor
lubrication, and quicker pulldown, resulting in longer compressor life
and lower energy cost. This unit is not only repaired, it is improved.
I have converted, after repairs, approximately sixty units to HC
refrigerants. This includes all models and types: trailer units, small
trucks, cold plate systems, etc. The results I see are low cost of product,
lower operating pressures, lower AMP draw (20-30% energy cost), quicker
pulldowns, no special oils to worry about, decrease in future repairs,
and better lubrication resulting in longer compressor life. My proof is,
I rarely see these units again for refrigeration problems. Change today to Hydro Cool's
hydrocarbon refrigerants and improve the environment at the same time.
