Oxygenation, Carbon Dioxide and Nitrogen Pumping and Cooling Services

Portable In-Situ Oxygenation (I-SO) Service

Linde's In-Situ Oxygenation (I-SO) emergency service can quickly provide temporary oxygen-based aeration to increase dissolved oxygen (DO) as needed due to unexpected or expected water and wastewater treatment capacity problems or excursions.

Using oxygen instead of air eliminates nitrogen from the aeration system. This virtually eliminates VOC stripping from the water and minimizes foaming, which can foul equipment, impede mixing and further reduce oxygen transfer. In addition, the I-SO system provides excellent solids suspension and decreased odor emissions. By reducing total gas throughput, the oxygen-based system reduces emissions volume, which can help meet air emissions regulations.

Temporary Gas Supply

When your normal supply of industrial gases is unable to meet the flow, pressure or temperature of your temporary requirements or your supply has been interrupted, Linde Services Inc. can help address your temporary supply needs.

Our national distribution network of service centers and liquid plants enables us to deliver Nitrogen, Argon, Oxygen, and Hydrogen, in either liquid or gaseous form whenever and wherever you need service. With a fleet of pumpers, vaporizers, transports and tube trailers, nearly any combination of pressure temperature and flow rate can be supplied for hours, days or months.

We are capable of offering supply alternatives to refineries, chemical plants, pipelines, and more - to keep your systems operating safely whether you're experiencing unexpected supply disruptions, difficulty meeting short term demand, or unusually high production rates.

Guided Wave

Linde Services Inc. offers long-range Guided Wave Ultrasonic Testing (GWUT) for piping, a means to rapidly screen piping systems by measuring the propagation of a specific form of low-frequency ultrasonic waves.

With miles of piping in your operation, there are distinct areas where it is difficult to determine the extent of corrosion or other defects. Certain sections of your piping system may be inaccessible for visual or hand-held ultrasonic testing (UT) inspection and incompatible with in-line inspection tools, making these or other analyses impractical.

Concrete Cooling

With our mobile nitrogen pumping equipment, Linde Services Inc. has the ability to provide a turnkey concrete-cooling service on-site at almost any location with proven reliability critical to any concrete-cooling operations.

Traditional liquid nitrogen cooling systems require a permanent or semi-permanent cement base to anchor injection arms. Our system is self-contained and we do not need to lay a foundation. After the nitrogen injection project is over, the Linde nitrogen delivery system is easily removed, returning the job site to its original condition.

We can provide liquid nitrogen for your most challenging concrete cooling requirements, temperature specifications during high heat conditions, and other pour jobs in need of concrete cooling, such as caps and columns, bridge decks and power plants have all been poured using liquid nitrogen.

SaFog Special Effects Service

Our SaFog special effects service can save your production time while providing a natural, non-flammable breathing atmosphere and safely created synthetic fog for the entertainment industry. The SaFog service produces a quality alternative to naturally occurring fog and our expert staff will coordinate the operating of the cryogenic equipment along with monitoring the fog activity while in use.

Our SaFog special effects fog mixture has been utilized for many major motion pictures. The Academy of Motion Picture Arts and Sciences honored the company with a Technical Achievement Award in 1998.

Nitrogen for Pipeline Freezing

Often, as part of a hydro-test, line freezing is required to isolate specific sections of piping. Linde Services Inc. can provide the equipment, liquid nitrogen, and manpower to safely assist with almost any line freezing requirements.

Nitrogen Cleaning and Target Testing

We offer Power Plants a safe, cost effective alternative to natural gas, for cleaning and target testing. Using our mobile nitrogen pumping units, we are able to provide a continuous flow of nitrogen that will ensure that momentum (velocity) specifications are satisfied, while avoiding potential dangerous ignitions and time delays associated with the use of natural gas.

Carbon Dioxide Services

When your operation calls for CO2 gas or liquid – Linde Services Inc. can supply your requirements. As the largest industrial gases company in North and South America, and one of the largest worldwide, our resources ensure the CO2 you need, when and where you need it.
