A Purge Systems Manufacturer

Purge systems are used to protect electrical equipment from flammable gases when installed in hazardous areas. The technique involves purging and pressurizing the equipment enclosure with an inert or nonhazardous gas. While some electrical devices can be protected by either making the system explosion-proof or intrinsically safe, in many cases these solutions are not possible or practical. In these cases, purge systems provide a low cost solution without interfering with the device's design or construction.

Description

 

Eclipse Technologies Z(Y)-Purging System is designed to provide safe monitoring of electrical equipment in Division 2 and Zone 2 hazardous areas.

 

An inert purging gas, either compressed air (preferred) or Nitrogen, is used to prevent a fire or explosion from occurring within the protected enclosure. The purging gas is used to dilute flammable products to a level below their lower explosive limit (LEL) to create a safe volume inside the protected enclosure.

 

Positive pressure within the enclosure prevents additional flammable products from entering the enclosure. Once the enclosure has been successfully purged, power may be restored to electrical equipment within the enclosure.
 

The control module monitors pressure levels inside the protective enclosure, and provides a warning alarm or a color indicator that activates when pressure drops below the safe working pressure of 1 inH2O. A continuous flow of purging gas is released into the protected enclosure to maintain positive pressure and compensate for enclosure leakage.
 

Eclipse Technologies Z(Y)-Purging Systems are certified for use in hazardous areas where the hazardous area is non-mining (above ground), and the hazard is cause by flammable gases, vapors, or dust.

 
 
   

Online water in organic solvents detector - NET 600

  

The NET-600 is an online detector for water in organic solvents.

The NET-600 is also designed to monitor low and high concentrations of CO and CO2 gas, as well as other traditional IR applications.

The NET-600 consists of an IR light source, a detector with a filter that isolates a specific IR wavelength, and flow cell.

The electronics board in the NET-600 controls a dual pyroelectric detector with individual optical filters for the analytical line. The light source is a subminiature tungsten lamp. The output is a 4-20mA signal proportional to the concentration of water or other chemical to be monitored.

The NET-600 can be operated in two different configurations, as a stand alone device with its dedicated controller, or as part of an integrated system where an industrial computer that is controlling other detectors and sampling system also controls the integrated NET-600. Ideal for applications that require various components to be detected simultaneously for example H2S and CO2 .
