The air conditioner i've started dismantling uses R410A and looking at the rating plate i need a heat exchanger rated at 36 Bar working pressure. after searching ebay etc. the best i can find are from Germany rated at 30 Bar.
Thanks steve

36 bar is a ridiculous pressure. 30 is just fine. R410 at 50C is just under 30Bar. What temps do you want to heat to? Above this temp, the HPs are usually CO2 or 2 stage units.
There are lots of SWEP or Alfa Laval HX rated and available.
Don't forget, if the HX is rated at 30bar, it has been tested to maybe 45bar
