Cleaner Air with a Variable Orifice Flare

Our patented flare has become the industry standard with its innovative design and 99% Destruction Removal Efficiency (DRE). Our variable orifice design efficiently and reliably combusts VOC emissions with its self-adjusting flare tip that uses site pressure to eliminate the need for electricity on-site. This innovative product design allows both high and low-pressure gas streams to be used on a single modular device, mitigating the need for multiple flares on one site while achieving smokeless operation in compliance with Quad-O, 40 CFR 60.18 EPA regulations.

The Steffes Variable Orifice Flare, models SHP-6, SHC-6 and SVG-3B4, are now certified under the North Dakota Department of Environmental Quality’s High Efficiency Program for 99.0% (DRE).


Design Features:

  • Self-adjusting design to meet flaring needs at various flow rates, including both High Pressure and Low Pressure
  • Modular construction of single, dual or multiple flare tip combinations
  • Field proven 99% DRE
  • Engineered to meet Quad-O & EPA 40 CFR 60.18 requirements
  • Service made simple with retractable pilot arm
  • Continuously lit flare pilot, perfect for retrofitting older flares
  • A reliable, patented complete site solution
  • Stainless steel construction

Compliment a Variable Orifice Flare with our Flare Accessories:

Steffes flare accessories allow you to customize your hardware to meet your flaring needs. Our experienced team can help you determine which flare accessories you need to maximize the performance of your Steffes flare.

Flare Controller
Whether you’re on-site or want to manage your flares remotely, the Steffes Flare Controller maximizes flare efficiency and ensures your flare continually operates to regulatory standards.

  • Smart ignition system
  • Temperature display
  • LED lights to indicate operation status
  • Solar panel, solar controller and battery
  • Thermocouple for monitoring pilot with data logger and temperature transmitter
Flare Extensions Kits

The flare extensions kits extend the height of the flare to stack heights to 20’, 30',  40’, and 60'.

Flare Knockouts
Fit your flare with a flare knockout to minimize the accumulation of liquids that are condensed from the relief gases.

Gas Assist Ring

Improve low pressure flare combustion performance with a gas assist ring.

  • Stainless steel construction
  • Increase operating range for smokeless flaring
Retractable Pilot Arm

The Steffes Retractable Pilot Arm is a reliable solution for safer flare maintenance. It eliminates the need for cranes, ladders or bucket trucks to service the flare pilot. Add it to a new flare or retrofit existing flares for service made simple.

  • Stainless steel construction
  • Fits both new and existing flares
  • Designed with safety in mind
Detonation Arrestor

Protect against flame propagation in piping systems by using a detonation flame arrestor. This detonation arrestor is bi-directional and is proven to stop ignited flammable vapor mixture approaching from either direction.

  • Maximum flow with minimal maintenance
  • Low pressure drop
  • Bi-directional
  • Easily removable flame cell
  • Available with ANSI, DIN and JIS flanges
