Air & Freeze

Microcare Anti Static Circuit Chiller

Anti-Stat Micro·Freeze is engineered for low-temperature,
non-destructive thermal testing of electronic components with
minimal static generation. Anti-Stat Micro·Freeze quickly chills components
to -45ºC/-55ºF or lower. This product is ozone-safe, non-toxic, plastic-safe,
and non-flammable. Use to cool equipment prior to testing, dissipate heat
when soldering, or test circuit traces for stress fractures or loss of continuity
and for thermally isolating intermittent components on circuit boards.

The difference is that the FRZA is anti-static. Hence the A in the part number. The primary ingredient, HFC-134A, is the same in both products.
If you look at the MSDS you will note that the FRZA has a small amount of alcohol. This provides the static protection if you were to use the FRZA on a board that had power.
This was a much bigger issue before the introduction of SMT technology and bed-of-nails testing.

Today FRZ outsells FRZA by almost 8-1. Fifteen years ago that ratio would have been reversed.

In the end they both work very well. Though the FRZA will evaporate a bit slower because of the small amount of IPA
