Company profile
CHIYO ENTERPRISES LIMITED is a comprehensive environmental protection equipment company serving pollution-control needs associated with semiconductor manufacturing and traditional industries. Its business integrates technology development, technical services, environmental equipment manufacturing, general project contracting and comprehensive utilization of resources. The company's environmental work centers on exhaust-gas treatment for manufacturing processes. Its reduction scope includes greenhouse gases, toxic gases and odors associated with semiconductor and traditional-industry operations. It also addresses process dust together with yellow and white smoke reduction identified as PM 2.5, with the stated goals of environmental pollution control and ecological-environment restoration. The greenhouse-gas scope specifically names PFCs Gas and HFCs Gas in connection with back-end exhaust from semiconductor and traditional-industry processes. Its registered business scope also includes local scrubber sales together with pollution-control and semiconductor-production-equipment related activities.
Exhibits
CHIYO ENTERPRISES LIMITED supplies a Plasma Water Washing tail gas (exhaust gas) treatment machine. The named machine belongs to the company's broader exhaust-gas treatment and environmental-equipment portfolio. Its core product categories include gas treatment, particle reduction, odor treatment and greenhouse-gas treatment. The Plasma water washing exhaust gas processor-CVD is identified as a Plasma water washing-CVD equipment type. For that CVD configuration, exhaust gas is preheated and then treated by vortex-plasma pyrolysis at 2,000~10,000C° before poison gas is dissolved by washing and the exhaust is water-washed for cooling and discharge. The CVD plasma-water-washing processor lists PFCs Gas including CF4, SF6 and NF3 as process gases. The Combustion water washing exhaust gas processor uses natural-gas pyrolysis for toxic gas and vortex water flushing that keeps the chamber below 50 degrees. After the combustion stage, poison gas is dissolved by washing and the stream is water-washed for cooling and exhausting; the listed process gases again include PFCs Gas such as CF4, SF6 and NF3. The Heating water washing exhaust gas processer applies high-temperature heating at 600~800C° before water washing to dissolve poison gas and cool the exhaust. For the general heating-water-washing configuration, the listed process-gas scope is waste gas that can be pyrolyzed or oxidized and then washed by water. A Water washing exhaust gas processor sends exhaust gas through washing chambers 1, 2 and 3 and uses normal-temperature water for gases that can be water-washed at normal temperature. An Adsorption exhaust gas processor routes exhaust gas into an adsorption bucket for adsorption of specific waste gas by adsorbent at normal temperature. A separate Heating water washing exhaust gas processor is designated only for MOCVD and uses 600~800C° pyrolysis followed by poison-gas washing and water-washing cooling and exhausting. The MOCVD-specific processor lists NH3, SiH4 and H2 as process gases. Across these equipment types, CHIYO ENTERPRISES LIMITED combines high-temperature cracking or pyrolysis, water washing, adsorption and cooling steps according to the gas and process requirement.
