chiller

Finally...the technicians started work on the chiller on at 6am this morning. but uncoordinated efforts stretched out the whole procedure to finish at 3PM.
This is the problem they found. Freon in the cooling system was undercharged, and that the flow of the refrigerant was hindered by the filter. The original System was a closed circuit configuration, so diagnosing the problem took some time. The tech had to blowtorch the pipes apart and put in an access valve to pump in the new freon. Mind you, this operation rendered the fridge useless as the ambient temperature was in the mid 20s.
The filter to be replaced is a big sausage of copper tubing (see photo). the replacement was half the size, and according to the tech, more efficient. So they placed in the new filter, cleaned out the compressor, and recharged the system with fresh freon. The gauges at 15Psi indicated that the system had no known leaks.
Progress was found after a 3 hour observation period. The temperature went down to ten degrees. I asked if it was possible to go down to five. Tech says not possible since it would be taxing on the compressor. Good enough. The ambient temperature stayed at 8 degrees. Cool.
Now we would be observing the fridge for the next few days to see if it will keep our sauces and veggies in servicable condition. We wouldn't want to serve little microbial villages to the guests, lest it was the end of the world.
tech from Besterm Technologies were very helpful and explained to me in idiot terms how these fridges work. It would be great if their service was consistent.
