Dear colleagues! We ask you to provide a commercial proposal for the production screw expander: Working fluid - R245fa  or another equivalent fluid Inlet pressure 5 bar Outlet pressure 1 bar Inlet temperature - 65 oC Outlet temperature - 20 oC Mass flow 1.5 kg/s Inlet volume flow 200 m3/hour Outlet volume flow - 950 m3/hour Under these conditions, we plan to install a unit with 50 kWe. For additional questions, please contact me as soon as possible.
