I don't know of any; I think the pressures of R410A may be too high. Might check with Recold.

So long as it rated for operational pressures, where is the problem. Total heat of rejection is the primary factor.

The manufacturers should be able to give you a correction factor for R-410a. Since they already have R-22 ratings I suspect the correction factor would be based on the R-22 data.
I looked at this one time. R-410a looks like a good refrigerant except for the high pressure. If you use a lower condensing temperature you should be below the manufacturers maximum pressure rating.

Dont use an r-22 coil, there rated at 300 psi. 410-a is rated to 450 psi. on residental and most light commerical package units as well. Hope this helps.

Oh most manufactures have coils rated for both but you need the correct txv.

The condensing temperature/pressure will determine the required design pressure. If it's air-cooled then the design pressure would of course be much higher.
