High Side Low, Low Side Low

[VTP99]

[QUOTE=k-fridge;10425412] I think we'll see it go away in a few years.

Honeywell considers it long term on there Guide to Alternative Refrigerants.
Along with R404a,R507,R422a,R422d,&R407c.
I personally think it should be banned in small cap tube reach-in's.
On the flipside those Artic Air Freezers can get down to -30*
Also many domestics refrigerators run the low side in vaccum.

I would guess your low side should be at about 4psig. Which would give you about a -5* cold wall.
How old is that equipment ? Got a serial # ?

The serial number is JA0995. I think it means it was made in 95. The newer models use a TXV.
