Hi guys, hope u are fine, first thanks for your explanation, thean I want to know where can we by the circular blue stuff you use to manipulate the freezer??
Hi! The expansion tank is installed in the 2nd stage refrigeration circuit. The expansion tank is connected to the compressor's suction side by a valve and expansion device. When the system is approaching its operating point, the expansion tank adds more refrigerant to the system.

Hi Abdul, We use this 40 inch, 2,000-pound turntable from Global Industrial: www.globalindustrial.com/p/pallet-skid-carousel-turntable-rotating-ring-2000-lb-capacity As of yet, we have not had any Sanyo ULT freezers through.

A r404A compressor with r404A refrigerant easily could get -40°C. If it use blend refrigerant, maybe it could get -55°C as well. (Just make sure the ambient temperature lower than 30°C and better it has fan cooler) China product now so cheap.
@@myselfnegative4290 If I add a bit of R1150 to R290 would it reach lower temps? or the boiling point is too far apart to be useful without tremendously increasing the high side pressure? Maybe with significant subcooling?
@@teresashinkansen9402 yeah, it works. But you need adjust the mixture that r1150 not so high and raises discharge temperature -pressure that compressor would not stand. A good refrigerant blend need time and experience to adjust, depends on your purpose, available materials, compressor type etc...
@@teresashinkansen9402 i've tried a mixture of R23, R32 and etc, obtained -50°C high-capacity, non-fluctuation temperature. Discharge temperature 70-80°C, oil bath temperature 60-70°C, condensed liquid mixture kind of high (measured on condenser outlet pipe: 33-35°C). Thanks to standard outside temperature (high), then i just obtained -50 to -52°C at evaporator). Designing ultralow temperature system needs money first, available refrigerant and hood material to gain the heat exchange efficiency.
@@teresashinkansen9402 forgot to say, need quite good oil-separator. Without it, oil will be easily clogged inside evaporator in lower -55°C. So, maybe -60°C will be the threhold of your system if you dont apply one good oil separator. The normal oil separator one, couldn't filter 100% oil particles so you need a designed oil separator with certain refrigerant mixture.
Maybe you guys can make a video of a rebuild.
Hi.... I have a burnt compressor in one of those ULT. Do I need to get the exact replacement or something similar could do?

Where did y’all learn to flush with alcohol?
Thank you for sharing .
Where do you get the turntable.
Have you work on Sanyo Ultra low Freezer
Hi Abdul,
We use this 40 inch, 2,000-pound turntable from Global Industrial: www.globalindustrial.com/p/pallet-skid-carousel-turntable-rotating-ring-2000-lb-capacity
As of yet, we have not had any Sanyo ULT freezers through.
My low side compressor gets over heated and trips off after 30 minutes what could be the fault
Hello, how do you weld the oil separator, what type of welding do you use? thank you

How much does this service cost?
Hi! It depends on how bad the system is, the cost is $1,500 to $3,000 (but we don't really do contract repair work).
Hi there, my thermo ult freezer’s compressor is not working, any info on the places that sell a new compressor? Thank You!
Hi,
We purchase new compressors for our freezers from Allied Supply Co. www.alliedsupply.com/
@@newlifescientificinc.789 thank you!
Where can we find spares for ult in India
What do you think of the north air ultra low freezer on Amazon? It reaches -40c and it’s only $400 including tax! Too good to be true right?

What temperature does the first stage evaporator work at?
Hi! Depends on manufactures, refrigerant and temperature.
@@newlifescientificinc.789 whats is our name tô fluid
Hi my name is Raju I'm allready it' s gas charging but 75.degre rech temperature not rechd -80
What problem
Cen i call you sir
Why not just replace the compressors? The reed valves could be gone.
because new compressors will need oil change too.(factory oil not working in cascade systems.)
Help me make one for under 100 dollars
Ok a grand....
You know how come on "spill it".lol
