ʻO Zhejiang Kaishan Compressor Co., Ltd. kahi ʻoihana compressor ʻoihana me ka ʻoi aku o 60 mau makahiki o ka mōʻaukala. ʻO ia i kēia manawa ka mea hana hoʻoheheʻe ea nui loa ma Kina, a me ka mea hana hoʻoheheʻe uila nui loa o ka ʻāina ma ke ʻano o ka hana ʻana a me ke kūʻai aku. Ma 2017 ua kokoke ka loaʻa kālā o ka hui i RMB 2.2 biliona. ʻOiaʻiʻo, ʻoi aku ka kiʻekiʻe o ka nui o kāna hana a me kāna kūʻai ʻana ma mua o nā mea hoʻokūkū ʻē aʻe ma Kina, me nā hui multinational.

ʻO nā huahana koʻikoʻi o ka hui ʻo ia ka screw air compressor, refrigerant compressor, screw expander, gas compressor, a me nā huahana no ka ʻenekinia kaiapuni a me nā ʻoihana kaulahao anu. ʻO nā mea hoʻopaʻa uila ka mea nona ka mana mai ka 4kW a hiki i ka 630kW, a uhi ʻia ka mana kaʻa, ka mana diesel, ka mine shaft explosion-proof screw compressor a me ka mea hoʻopaʻa hoʻopaʻa paʻa pālua.

ʻO ka ʻenehana hoʻonui Screw kahi ʻenehana hoʻomohala haʻahaʻa haʻahaʻa e alakaʻi nei i ka honua, a me ka hoʻonui pololei ʻana me ka hoʻohana ʻana i ka wela koena a me ka ʻenehana hoʻonui Rankine Cycle (ORC). Hiki iā ia ke hoʻohana i ka wela haʻahaʻa haʻahaʻa haʻahaʻa a me ke kaomi i ke ʻano tiered a maikaʻi loa, me ka maikaʻi a me ka hilinaʻi i alakaʻi i ka honua. Hiki ke hoʻohana ʻia ka ʻenehana ma ka laulā nui i nā kumu mana hou a me nā kumu mana recyclable e like me ka hana geothermal power generation, koena-wela mana hana, bio-energy power generation and residual-pressure power generation.

Ma 2009 ua hoʻokumu ʻia ʻo Kaishan ma Seattle ma United States, "Kaishan North American Research Center". Ma muli o ke kumu hoʻohālike o "Developed in America, Made in China", ua hoʻomohala ʻo Kaishan i kahi helu nui o nā huahana kiʻekiʻe i loaʻa iā ia ka waiwai naʻauao. Ma muli o ka waiwai nui o "ka hāʻawi ʻana i ka hoʻohana noʻonoʻo ʻana i nā kumu waiwai o ka Honua", ua pōkole ʻo Kaishan i hoʻokomo iā ia iho i ke kahua honua, a lilo i mea hana compressor poʻokela.

Me ka ʻoi aku o 2,000 mau hale kūʻai kūʻai ʻo Kaishan e uhi ana i Kina a pau, e hāʻawi ana i ka lawelawe kūʻai maikaʻi i nā mea kūʻai aku. Ke kūʻai ʻia nei kāna mau huahana ma mua o 60 mau ʻāina a me nā ʻāpana o ka honua, me ʻAmelika Hui Pū ʻIa, Kelemānia, Iapana, Korea a me Rusia.
