Natural gas filters, strainers, scrubbers for instruments

 In Gas Filtration

Natural gas contains impurities. Foreign material such as loose scale, rust, weld beads, grit, or other contaminants may damage expensive downstream equipment. For this reason, natural gas filters, strainers, scrubbers, and natural gas dryers become an inexpensive and effective way to prevent equipment damage and failures.

Linc Energy Systems is pleased to announce that one of our principals, IMAC Systems, released new gas filtration products.

Eliminator Pilot Filter

The IMAC Eliminator Series is a particulate and coalescing filter. The end-user can use it as a pilot filter, chemical injection filter, sample protection filter, gas analyzer filter, catalytic heater filter, or instrument filter. This air and natural gas filter performs at high pressure (MOP of 5000 PSIG) with a 316L stainless steel filter assembly.

The NGS1000 Natural Gas Scrubber is for industrial applications.

High-Pressure Instrument Filter Dryers

IMAC Instrument Filter Dryer, a desiccant dryer, provides cost-effective filtration to supply gas for high-pressure control instrumentation, such as pneumatic controllers, catalytic heaters, enclosure systems, and other instruments. The removal of contaminants helps eliminate costly downtime and increases the performance life of the equipment it protects. The IMAC natural gas dryer removes particles, moisture, H2S, odorant, and other impurities down to 3 microns. The IMAC desiccant dryers are available in various assemblies to accommodate the applications; pressure cuts (regulators), gas conditioning (catalytic heaters), automatic filter switching, and drain valve. The units are easy to install, provide trouble-free maintenance and maximum scrubbing. Removing unwanted contaminants helps eliminate costly downtime and increase performance and longevity for equipment downstream.

Low-Pressure Instrument Dryers

IMAC Systems offers two low-pressure instrument dryers, the Flo-Dri Filtration and Natural Gas Scrubbing systems.

Flo-Dri gas scrubbers are for gas conditioning appliances, such as instruments and catalytic heaters. The filter systems remove aerosols, contaminants, H2S, moisture, oil, and solids, eliminating costly downtime associated with catalytic heater failure. The patented design is engineered for long life, low maintenance, and easy cartridge change-outs. The units remove particles down to 0.5-micron and have various sizes to accommodate flow rates from 1-150 SCFM and perform up to a working pressure of 250 PSIG.

NGS 1000 natural gas scrubbers are for gas-fueled catalytic heaters (and other fueled appliances) in industrial applications. The NGS 1000 features a desiccant-based scrubber cartridge that is easily installed and maintained. The unit removes particulates down to 0.5-micron and has two sizes for applications having flow rates of 10-25 SCFM and a working pressure of 250PSIG.

IMAC filter dryers are appropriate to protect gas supply to:

Natural Gas Strainers

In addition to gas filters, inline strainers are an inexpensive way to remove harmful debris from natural gas to protect equipment. Various styles and sizes are available, including T strainers, gasket strainers, and temporary strainers (witches hat strainer, cone strainer, plate strainer, and basket strainer)

    Good afternoon,

    My name is Ken Bertelsen. I own and operate a small metal fabrication shop in the Black Hills of South Dakota named N-Line Fabrication & Design Mfg. LLC. We currently hold our “U” and “R” stamp certifications with The National Board and ASME for pressure vessel manufacturing along with specializing in B31.3 certified pipe welding. We primarily focus on gas compression, but have experience with separating units and treaters as well as VRU and LACT units. With the appropriate blueprints and information we can accomplish great things.
    N-Line Fabrication is not a large company. We have a total of 8 employees. Small, but ferocious… We fab the smaller projects that larger companies don’t care to mess due to smaller margins, time constraints or general overflow. Our low overhead allows us great flexibility when it comes to quoting projects and we offer the best shop rates in the region. To be clear- N-Line Fabrication & Design Mfg. will never sacrifice top quality or our company name for anyone or any thing. We have a combined total of almost 100 years in this industry.
    With that being said, to be completely honest with you, we wish to make you a contact for business opportunity. I’m not a salesman, I am a metal fabricator. I work side by side with my guys out in the shop and we are a great team… I dislike making cold calls and sending out emails like this because it seems to take the personal touch out of business communications, unfortunately, with the market being as tight as it is, I have little choice. I need to reach out. I would much rather speak with you in person or on the telephone about what N-Line can do for you and your company. Perhaps if you find time in your undoubtedly busy schedule, you might call or email and get to know us a little bit.
    If you have any questions, by all means please contact me, I am always available. Thank you very much for your time and consideration.

    (Family man, fabricator, all around decent Christian fella)
