Gate Station Skid

Campos Fabrication is working with the Emerson Impact partner network to provide and integrated odorant solution. The Emerson Tartarini™ Type DO200 Odorant Injection System, the newest iteration of Dosaodor Odorizer, is available for use in Campos Fabrication Skids. Using differential pressure that may already exist in your application, such as the upstream and downstream of a regulator, the DO200 can achieve a more uniform distribution of odorant with smaller injections done at a higher frequency. This pumpless system has very few moving parts, which results in minimized maintenance costs.

Other benefits of the DO200 turnkey skid include:

• High turndown ratio
• Zero Emissions and Reduced Environmental Impact
• Automatic calibration of the system during active use
• Hazardous environment rated
• User-friendly configuration software
• Several Back-Up and Redundancy Options
• Easy Integration with FlowBoss and ROC RTUs
• Rosemount 5300 Guided Wave Radar Level Transmitter
• Anderson Greenwood ASME Relief Valve
• Campos Fabrication ASME U Vessel with custom sizing and pressure rating available

The DO200 is also certified as Explosion Proof Class 1 Div 1 and 2, has a maximum Supply and Injection Working Pressure of 1450psi/100 bar and a temperature range of 14-140°F (-10 – 60°C), allowing for its use in the most challenging of environments. Higher pressures are available upon request. Campos Fabrication, in partnership with NECI, can also provide a turnkey solution, with the control panel, odorant tank, and injection system, at a competitive price and lead time. In the past, Campos Fabrication has successfully implemented this turn-key integration, providing an OEM solution on RNG interconnect skids for multiple clients across the country, and is proud to now provide a drop in solution for existing regulator stations as well.
