The manufacturer of the world's largest ozone generators is using gas detection equipment to safeguard operators of its products
Ozonia supplies turnkey installations, some producing several hundred kilograms of ozone per hour, for diverse processes including drinking water purification, wastewater treatment, chlorine-free bleaching and pharmaceutical applications.
The company now incorporates Crowcon ozone detectors, oxygen detectors and control panels into its generator packages to ensure that personnel are never exposed to dangerous gas levels. Because ozone gas is toxic even in very low concentrations, legislation in most countries stipulates that generator rooms must be monitored continuously for leaks.
Some generators, depending on the application, produce ozone using a supply of pure oxygen; in such cases, rooms must also be monitored for oxygen leaks which would represent a serious fire hazard if unchecked.
Ozonia uses Crowcon's TXgard remote gas detectors and Gasmaster control units to provide a range of automatic safety responses in the event of a hazard.
If a detector senses a dangerous gas level, the control unit automatically shuts down the ozone generator and triggers audible and visual alarms to alert personnel in the vicinity.
Typically, it will also increase the rate of ventilation in the area, and may even lock the generator room doors if no personnel are present.
Ozonia was attracted to Crowcon's Gasmaster controllers by the variety of configuration options available.
As well as dedicated alarm relays, the units incorporate industry standard 4-20mA and 1-5V outputs to operate a range of external equipment according to the requirements of each installation.
Smaller plants are protected by one ozone detector and a single-channel Gasmaster 1 unit, while for bigger installations, the four-channel Gasmaster 4 is used in conjunction with multiple detectors.
The largest plants, and those where gas leaks are possible in more than one room, utilise multiple control units.
