ORC SCREW expander power generators employ world-leading Rankine Cycle power generation technology that gives isentripic efficiency of as much as 85% for their expander unit such as to achieve net power generation of 135KW under conditions of 2.57 tons per hour,100? saturated steam and 20 °C cooling water. Organic medium in the unit  undergoes rankine cycling in a sealed interior. It absorbs heat from high-temperature source and release heat to low-temperature source, thereby generating shaft power. The products require relatively low conditions to operate and hence are suitable for recovering energy from low-grade heat source.

     The wide range of flow and differential pressure make the kaishan screw steam expander power generators cover a very wide range of applications. It has high power generation efficiency within steam flow 1-20 t/h and the diferential pressure 0.15-2.5 Mpa for a sigle expander. With 0.5 Mpa and 1 ton/hr of saturated steam, the Kaishan Screw steam expander with ORC screw expander has a net generating capacity of at least 102kw, not only muh higher than that of steam turbine set, but also higher when compared to any similar productsat nome and abroad.

     The models with 50 Hz using saturated steam are as follows:
