Our Products

Our product is OTH series Chemical Chlorine Dioxide Disinfectant Generator. Adopting the advanced technology from China and foreign countries, OTH ClO2 Generator has good performance and high level of automation. This low-cost generator could be operated simply and maintained easily. It is widely applied in water supply system, recycled water disinfection, hospital wastewater disinfection, industry circulating cooling water, wastewater treatment of papermaking, and dyeing industry etc. After treatment, the water quality could conform with the Sanitary Standard for Drinking Water (GB 5749-85) or the Integrated Waste Water Discharge Standard (GB8978-1996). In year 2003, when SARS break out in China, OTH’s products used in lots of hospitals national around had indelible effect for controlling disease spread. It is also worth mentioned that Hainan Qionghai Water Supply Company who could supply good quality of water for 2005 Annual Conference of “Boao Forum for Asia” use OTH’s ClO2 Generator.

Performance of Leading Products

OTH Series ClO2 Disinfectant Generator applies HCl-NaClO3 chemical method to generate ClO2. The Reaction System is made of heat-resistant and corrosion-proof composite material and the spray lacquer baking varnish on metal products of the crust improve its corrosion resistance. Concerning about the specific technical performance of our Leading Products, please find the information as following:

 

OTH2000 Series

  • Use aerating technological process with negative pressure to generate the composite product of ClO2 (main product) and little Cl2. the transforming rate > 82%, content of ClO2(active chlorine)> 70%.
  • Adopting intellectualized numeral controller and touch panel. It can realize automatically control temperature (ensure the best reaction temperature 70℃) and pressure.
  • Raw material supply system adopts Germany metering pump and it can exact measure and reliable work.
  • The alarm system will work when lower dynamic water pressure, higher temperature or other malfunction happened.

 

OTH2001-LPR Series

  • OTH2001-LPR Program Automatic Series ClO2 Disinfectant Generator retrofitted and designed on the basis of OTH2000’s new technology. But it has higher degree of automatic, security, stability, dependability and promotes the conversion ratio.
  • Use aerating technological process with negative pressure to generate the composite product of ClO2 (main product) and little Cl2. Transforming Rate > 85%, content of ClO2(active chlorine)> 70%.
  • This equipment adopts high reliability Program Logical Controller (PLC) and Human-Machine Interface (HMI) System. It is self-controlled according to the input data of temperature, the amount of residual chlorine and the frequency of metering pump. It shall be automatically switched off upon receiving the alarm signal which is deepened on the setted parameters of hydraulic pressure and liquid level.
  • Touch LCD screen can directly complete the system operation such as parameter setting, data collection and real time data processing. The control panel shall display those informaiton as the state of the equipment all the time, operate instructions and setted parameters. Meanwhile, it shall be capable of encrypting the pages with important parameters.
  • Germany Siemens Program Logical Controller (PLC) which we use has RS485 standard communication interface which in conformity with multiform communication agreement. The controller shall be capable of remote switchover or switching over at the side of the equipment. Interfaces shall be provided for the control equipment to connect with the control system of the whole plant so as to realize the overall remote monitoring and control.
