Cu/Ni condenser,32 bar,9 kW for R410A/salted water

Hello,
for our new generation of swimming pool heat pumps, we need to switch over to the new refrigerant R410A, which means we need a pressure rating on the refrigerant side at least 32 bar (450 psig?).

At the same moment we need to use salted pool water on the secondary side.

Can anybody deliver any condenser 32 bar, 9 kW capable of handling salted water? (Cu/Ni, titanium coaxial possibly)

I am ready to send the calculation of a (plate) condenser that we need to replace.

Awaiting any suggestion.
with advance thanks
