Re: R410a evaporative condenser
I don't know of any; I think the pressures of R410A may be too high. Might check with Recold.

Re: R410a evaporative condenser
So long as it rated for operational pressures, where is the problem. Total heat of rejection is the primary factor.

Re: R410a evaporative condenser
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.If all else fails, ask for help.

Re: R410a evaporative condenser
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.

Re: R410a evaporative condenser
Oh most manufactures have coils rated for both but you need the correct txv.

Re: R410a evaporative condenser
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.
If all else fails, ask for help.
