R410a For Low Temp/low Pressure

[ralph feria]

Does anyone have experience using R410a in low temp or low pressure applications? I am looking for compressors that are approved for this use. Yes a compressor for R404a would work just fine, but i need the compressor to be labeled for R410a use at low pressure/low temp conditions.

Thanks!!

I think Copeland make some R410A condensing units.
