The present invention relates to an improvement provided to a pressurized close-cycle machine that has a cold-end pressure vessel and is of the type having a piston undergoing reciprocating linear motion within a cylinder containing a working fluid heated by conduction through a heater by heat from an external thermal source and to a method using said machine. The improvement includes: a heat exchanger for cooling the working fluid, the heat exchanger comprising a first material in thermally conductive contact with the working fluid, and a second and distinct material in thermal conductive contact with a coolant fluid; and a continuous section of coolant tubing providing for circulation of the coolant fluid to outside the pressure vessel, wherein a section of coolant tubing is contained within a cooler for directing a flow of working gas across the coolant tubing.
