Portable Chlorine Dioxide Gas Generator

Electricide® CMG generator

Chlorine dioxide is a proven chemical for inactivation of viruses, bacteria, cysts, spores, molds and biofilms. It is a gas at room temperature and is generated at the point of application from a single precursor chemical. The CMG generator is a small footprint, portable chlorine dioxide generator designed to produce chlorine dioxide gas under slight positive pressure. The gas is directed from the outlet pipe of the generator into rooms, spaces or water circuits.

  CMG Chlorine Dioxide Gas Generator (37.1 KiB)

Benefits of the CMG generator

  • One precursor chemical: 25% or 31% sodium chlorite solution.
  • High efficiency electrochemical cell – low running cost.
  • Maximum output = 11 g/hr = 0.5 lb/day as ClO2.
  • Flexible, timer controlled operation of dosing. Touchscreen programmed times set for any combination of hours, days, weeks based on real time start and stop.
  • Optional connection of a ClO2 gas monitor to ensure gas concentration is correct.
  • Portable trolley mount. Wheel the generator to the desired location, connect power and the gas transfer hose then start dosing.
  • Easy handling of chemicals on the trolley.
  • Pressurized water accumulator tank mounted at trolley.
  • Optional remote internet access to generator.

Save time on labor for sanitization

Manual sanitization of hard surfaces with expensive alcohol based liquid chemicals is time consuming. The CMG generator can be setup to automatically dose chlorine dioxide gas into a room, sanitizing the surfaces while you wait. No labor required and no liquid sanitizer chemicals required.

Typical Applications

Hospitals

“Luftman et al. (2006) evaluated ClO2 gas used to decontaminate a 4800 m3 facility with a total ClO2 dosage of 400 ppm/hr in a single evening. This trial test proved ClO2 gas to provide effective disinfection in a normal hospital room.”

“Shirasaki et al. (2016) applied ClO2 gas as a sterilizer in a hospital room (87 m3) with concentrations from 0.8 ppm to 40.8 ppm for 2 hr to 3 hr. They were no differences in concentration between 0.1 m to 2.5 m above the floor. Under 80% relative humidity, the colony formation of both Staphylococcus aureus and E. coli was inhibited with 3 ppm exposure of ClO2 gas.”

“Liou et al. (2007) investigated the sterilization effect of indoor air of laboratories, hospitals and conference rooms using 200–1000 ppm ClO2 gas. At the end concentration of 625 ppm, the disinfection efficacy of 90% was achieved in 30 minutes.”

“Lorcheim (2011) confirmed that ClO2 gas can be used to treat beta-lactam manufacturing in a pharmaceutical plant. With various concentrations of ClO2 gas and exposure times, the pharmaceutical manufacturer asked for 3-log (99.9%) reduction of eight different beta-lactams on various surfaces.”

“Lowe et al. (2013) exposed ClO2 gas at 10 sites in a hospital room to evaluate the germicidal efficacy of 385 ppm ClO2 gas for health-associated diseases and pathogens such as Acinetobacter baumannii, E. coli, Enterococcus faecalis, Mycobacterium smegmatis, and Staphylococcus aureus. They verified that 7 to 10-log reductions of viable organisms could be achieved. Sealing of the doors of each room was implemented to prevent gas leakage.”

Cafeterias

“Hsu and Huang (2013) tested two different approaches of gaseous ClO2 releasing by an aerosol device in disinfecting a student cafeteria. One was a one-off treatment and the other was a twice-daily treatment. The bioaerosol levels of bacteria and fungi were measured. The air quality before and after disinfection was evaluated. They measured that the average levels of bacteria and fungi decreased 65% and 30% from 972.5 ± 623.6 and 1534.1 ± 631.8 colony-forming units (CFU)/m3, respectively, in the one-off treatment. The twice-daily ClO2 treatment enhanced the reduction levels of bacterial and fungal concentrations by 74% and 38%, respectively.”

Medical Cannabis Greenhouses

Chlorine dioxide is effective for control of odor and powdery mildew. Gas is introduced from the CMG generator into the air ventilation system to ensure even dispersal at low concentration.

Cooling Towers

Small cooling towers utilise timer controlled dosing of ClO2 into the circulation line or into a bypass loop around the sump using an eductor. The CMG generator can be located outdoors next to the cooling tower as the cabinet is weatherproof and chemical resistant.
