Callidus Flares

nViro-XSR™ Flare

Cost-efficient smokeless flare technology


Utilizing our advanced computational fluid dynamics capabilities coupled with industrial-scale physical testing, our combustion experts created this next-generation, ultra-low steam consumption flare to break through the barriers of traditional design. The Callidus nViro-XSR is a safe, efficient combustion solution to comply with the latest government regulations.

Callidus nViro-XSR flare tip is designed to provide:

  • Lowest operating cost by using less steam and supplement gas
  • Increased hydraulic capacity
  • Increased maximum smokeless rates for regulatory compliance
  • Low noise with operation proven by industrial-scale testing


  • Lower standby steam requirement
  • High smokeless operation capability
  • Increased hydraulic capacity
  • Requires a lower backpressure
  • Single-valve steam control
  • Integrated noise reduction technology
  • 70% weight reduction of flare tip
  • Reduced wind-load surface area


  • Reduced operating expenses up to 3.6 times
  • Protection against visible emissions violations
  • Reduced community impact during flaring events
  • Ability to accommodate higher flow rate flaring events without visible smoke
  • 57% increase in smokeless rate
  • Simplified installation and operation
  • Reduced component count
  • Single point of control


  • Retrofit installation for older flare tip styles without modifying support structure
  • Upstream, midstream and downstream processing
  • Petrochemical processing
  • Chemical/specialty processing
