Holtec provides an impressive portfolio of expertly designed nitrogen (N2) gas generators for industrial on-site nitrogen production. With over 140 years of combined engineering experience in the gas separation industry, Holtec offers a wide range of nitrogen generators.
Pressure Swing Adsorption (PSA) Nitrogen generators use adsorbent material to extract oxygen molecules from other gases, leaving behind an inert product stream that is mostly nitrogen. They are used to generate nitrogen on demand, eliminating the need for cumbersome nitrogen gas cylinders or liquid nitrogen tanks. By selectively capturing and removing oxygen from the compressed air, PSA generators deliver a continuous, reliable source of nitrogen gas. They can also deliver extremely high-purity nitrogen gas levels tailored to specific requirements.
Membrane Nitrogen Generators rely on selective permeation using hollow fiber membrane bundles to separate nitrogen from other gases in the air. Like PSA generators, they produce nitrogen on-site at low to moderate (99.5%) purity but are more compact than PSA generators. For higher purities, membrane technology is far less cost-effective and usually supplanted in favor of PSA technology. These generators offer a reliable, cost-effective, and eco-friendly alternative.
Nitrogen is typically produced from atmosphere at pressures between 75-200 psig. Where higher pressure is needed, N2 boosters are employed to elevate the pressure of nitrogen gas beyond what the nitrogen generator can provide. This ensures a steady and adequate flow for various applications. Boosters contribute to increased productivity and reduced downtime by maintaining precise pressure levels. They also ensure a steady and adequate flow for various applications.
At Holtec, we also provide comprehensive Aftermarket Services for our nitrogen generators, boosters, and systems. We can also advise on or repair nitrogen generators from other manufacturers.
If you are looking for nitrogen generators to produce your own nitrogen on-site, you’ve come to the right place. At Holtec, we understand that selecting the right system can be a challenge. Our goal is to make complex technology simple to buy, use, and maintain.
We carry 4 families of generators from which you can choose. Selecting the right type will depend on the following aspects:
The Holtec line-up includes systems as small as a cabinet that produce up to 75 SCFM. We also produce large modular systems capable of producing over 2300 SCFM each. Depending on your nitrogen usage, there’s a Holtec generator that can fit the bill.
Many customers learn about the purity of nitrogen by checking the certificate on the nitrogen they are currently buying. This negates an important advantage of generating your own nitrogen, which is tailoring the nitrogen purity to your actual needs. Only in this way can you achieve maximum cost savings.
To suit your application, Holtec’s nitrogen generators produce from 95% to 99.9995% pure nitrogen depending on the generator you select.
Our experience shows that setting up on-site nitrogen generation goes beyond the physical environment of temperature, humidity, and weather exposure. It also includes significant consideration for the individuals who are responsible for the day-to-day operations. This includes safety protocols, environmental awareness, and site accessibility, among others.
Since the handling of nitrogen gas presents inherent risks, operators working in these environments must adhere to strict safety protocols. Operators should undergo comprehensive training programs covering nitrogen hazards, safe handling procedures, and emergency response protocols.
Protective equipment, such as safety goggles, gloves, and respiratory protection, should be readily available and used as needed. Proper labeling of nitrogen pipelines and storage containers should be used to prevent confusion and accidental mixing with other gases.
Regular equipment inspections and maintenance are crucial in preventing leaks or malfunctions that could lead to nitrogen exposure. Nitrogen generators should be well-ventilated to prevent gas buildup, and nitrogen storage areas must be clearly marked and secure.
Clear signage, safety barriers, and restricted access zones should be established to prevent unauthorized personnel from entering hazardous areas. Furthermore, continuous monitoring of nitrogen gas levels in the work environment is essential to detect any sudden changes or leaks.
Emergency response plans, including procedures for nitrogen exposure or gas leaks, must be in place, and all personnel should be familiar with them. Regular safety drills and exercises help ensure everyone knows how to respond swiftly and effectively in case of an emergency.
Nitrogen is a versatile gas with numerous applications across various industries. Here are some common applications of nitrogen:
Nitrogen is used to displace oxygen in food packaging containers. It preserves freshness and extends the shelf life of products like snacks, coffee, and potato chips. Many companies also use nitrogen to preserve raw ingredients and reduce spoilage.
In the pharmaceutical industry, nitrogen is utilized for blanketing, purging, and inerting applications. It prevents product degradation and ensures the safety of sensitive pharmaceutical compounds.
Nitrogen is crucial for preventing oxidation during the soldering process in electronics manufacturing. It ensures the reliability of electronic components and circuit boards, and reduces rework.
Nitrogen is used for purging and blanketing in metal processing to prevent oxidation during annealing, heat treating, and welding processes.
Nitrogen is primarily used as an assist gas to protect the raw material from oxidation during the high energy laser cutting process. It also improves cut quality, allows for faster and more precise cutting and protects sensitive parts of the laser itself from contaminates.
In the oil and gas sector, nitrogen is used for well stimulation, pipeline pigging, and gas blanketing. This enhances oil recovery and prevents explosions in potentially hazardous environments.
Nitrogen is employed as an inert gas in chemical processes to prevent unwanted reactions and ensure the purity of chemical compounds.
In healthcare, liquid nitrogen is used for cryopreservation and cryosurgery. Gaseous nitrogen is used in various medical devices, including lasers and pneumatic surgical tools.
These are just a few examples of nitrogen's wide-ranging applications. Its versatility makes it an essential gas in many industrial and scientific processes.
