I hope you have better luck than I did keeping the high-pressure refrigeration gases from leaking out from MPT fittings. The refrigeration gasses are going through very large temperature cycles, to say nothing of the HX being subjected to vibration.
What you want on the refrigeration side is a "sweat fitting". Don't let the name fool you into thinking that it implies sweat soldering, that would be a mistake. You need to
braze your refrigeration tubing, in order to withstand the temperature cycling and vibration... Or else use a compression fitting, which this is not.
The HX you linked to is a water-to-water HX.
