The best one is the SANYO one. Never failed in our labs and we have quite a
lot of them

> A couple weeks ago I asked for input regarding -80 freezers. Some others
of you posted that you also were interested in information on this subject.
I posed the question of "which -80s are best" to the building manager of the
facility I used to work at. He's been the building manager there for quite
some time, and has seen a lot of freezers come and go. I thought some of
you might find his comments helpful,so I've appended them below. Please
note that neiter he nor I have any affiliation with any of the companies
> Hi Mike--
> You are correct when you note that I have bought a lot of So-Low
over the years. What I like about So-Low is that the cabinets are very well
made. We do not have the door/inner door problems with them that we do with
Revco. Their refrigeration system is the same as Revco, pretty much, and
they are less expensive, on the order of $5,000. The down side of the
So-Low is the fact that they are quite noisy.
> For those people who have more cash, I now recommend the Forma at
about $8,000. They are much quieter than any I have heard. They also now
have a lower and upper OUTER doors so that when you open the freezer, you
are only opening one half of it. This limits the frost build up and also, I
would think, the temperature fluctuations inside the box. My -80 repairman
likes the refrigeration system design that they employ. I do not yet have
adequate experience to forecast whether or not they will run longer between
compressor changes than the comparable So-Lows. Ask me in about 3 or 4 more
> As for reliability, a wise man (not me, that's for sure) once
said: "the question is, not IF, but WHEN your -80 will fail". Most upright
units run pretty well for about 5 years, and then need a compressor change
for about $1200. Chest units do much better, but require enormous amounts
of floor space which no one really ever has.
