Fieldpiece Charging Jacket S365

[RussellHarju]

Jim Bergmann from Trutechtools.com was kind enough to film a test of the Fieldpiece S365 charging jacket. This product allows you to charge TXV systems in weather between 37 F and 70 F. This allows you to extend the billable hours in a day or year and service your contractors during cooler parts of the year when demand calls are low. Check it out and let us know what you think.

Where was the low side sensor .2˚-.4˚SH

Was it 37˚F in the shop there?

I think Jim said it was in the mid 60's. I'm not sure what to make of the Superheat. But give it a shot in some much cooler weather and let us know what you think!

i've been blocking condensers for years.

is an excellent method to ensure charge when the weather man is wrong again

Has anyone used this yet?

Since my company wants us to do a/c service in cold rainy conditions, including fixed/piston units, can this work on those too?

I had a lesson on charging in cold weather and was shown to raise the indoor to 75° and block the top of the condenser. No SH or SC just 65 & 225 psig and a 17° temp split, R-22.

Ya like that? That is a training unit in my shop, the TXV bulb is loose. Students have to identify the problem. No worries though, it has an accumulator. I guess since you identified the problem you passed the test. 700+ views and you are the first to comment.

How accurate is it with a low evap load. Such as return dry bulb 65°?

Just as accurate as at 75 degrees. Or were you asking about the charging blanket? As far as that goes, there are only two things to be concerned with, do not freeze the coil, and do not crank up the head pressure to high. Neither were done in that testing.

i like the concept. It should work fine on txv systems, but piston systems could be undercharged and you would/could miss it.

[RussellHarju]

We only recommend using this on TXV systems for the exact reason you state.

Russ you may want to look at passing on specific recommendations on taking liquid line temps in cold weather in your manual. You can not simply clamp a ATC1 on a liquid line and expect to get a good reading @37˚F
