Will there be anny issues in using shell & tube type water cooled condenser with R410A in chillers? R410A being a high density refrigerant, will the shell and tube condenser increase the system charge drastically? Using a PHE or tube-in-tube is not an available option for us, due to alkaline water quality.

Is any manufacturer offering R410A water chiller of say 20TR - 30TR using scrolls?
