Where to buy coaxial heat exch. for refrigeration.

[JKProSoft]

Where I work we have been using coaxial heat exchangers as a built in pre-coolers. We have had some problems with our suppliers Shmöle, ACP sice they are not able to calculate their heat exchanger to use in refrigeration. We are using R404A. Does anyone know of a company which know what they are doing when it comes to calculating coaxial heat exchanger for refrigeration.
