Why brewers should consider a N2GEN-FLEX nitrogen generator

South-Tek Systems has launched the N2GEN-FLEX Nitrogen Generator, a new solution for on-site nitrogen generation. This system is designed to provide high-purity nitrogen for a variety of uses in a craft brewery. With nitrogen gaining some traction as an alternative to CO2 in breweries in certain applications, the N2GEN-FLEX arrives at an interesting time in the industry — when efficiency and unique approaches to beer making are helping streamline and differentiate brands. From the press release:

“We’re excited to introduce the N2GEN-FLEX to the market,” said South-Tek Systems CEO, Jens Bolleyer. “Our customers are looking for efficient, cost-effective, and flexible solutions. The N2GEN-FLEX delivers on our promise to provide our customers with the right solution for their applications. It reduces operational costs, lowers service maintenance, and provides reliable high-purity nitrogen whenever it’s needed, revolutionizing how companies handle their nitrogen requirements. This line of products represents the future of nitrogen generation.”

Why Nitrogen is a great alternative for breweries

Nitrogen offers a sustainable and cost-effective solution for many brewing operations. Unlike CO2, nitrogen is abundant, comprising 78 percent of the Earth’s atmosphere. This makes it a readily available resource that’s cheaper to produce and environmentally friendly.

Applications of nitrogen in brewing

Nitrogen can replace CO2 in several areas, including:

Purging tanks to prevent oxygen contamination.
Moving beer between tanks while maintaining product integrity.
Pre-purging brite tanks after cleaning and sanitization.
Blanketing gas during canning and seaming.
Nitrogenating beers to achieve a creamy mouthfeel.
Draft systems for nitro beers and high-pressure tap lines.

By adopting nitrogen, breweries can reduce their dependency on CO2, especially during shortages, and improve their sustainability efforts.

Meet the N2GEN-FLEX

The N2GEN-FLEX is South-Tek Systems’ latest innovation, offering industry-leading performance and efficiency for nitrogen generation. Designed with breweries in mind, the system provides a reliable, on-demand nitrogen supply at a fraction of the cost of purchasing cylinders or liquid nitrogen. From the press release:

“The N2GEN-FLEX’s low air requirement and minimal pressure drop allows users to pair it with a smaller compressor than the standard PSA nitrogen generator, saving money in up front cost, electrical demand, and system maintenance,” said South-Tek Systems Mechanical Engineer, Garrett Rinker, Ph.D. “As a result, the N2GEN-FLEX provides a longer-lasting, more reliable solution that saves businesses both time and money— with full control of their operation at a predictable cost, without dependence on nitrogen delivery and supply chain volatility.”

Key features of the N2GEN-FLEX

Pressure Swing Absorption (PSA) Technology: This ensures the most efficient air-to-nitrogen ratio, reducing energy consumption by over 20 precent.
High purity levels: Delivers nitrogen at 95 to 99.999 percent purity to meet brewing standards.
Wide range of flow rates: Supports flow rates from 400 to over 2,200 SCFH to handle operations of all sizes.
Energy efficiency: Computational fluid dynamics (CFD) optimize performance, delivering substantial energy savings and rapid ROI.
Long lifespan: Designed for durability, minimizing maintenance costs and downtime.

The N2GEN-FLEX caters to breweries of all sizes, providing scalability and flexibility to support their growing needs.

Nitrogen as a solution — especially during CO2 shortages

Recent CO2 shortages have disrupted brewery operations, leading many brewers to explore nitrogen as an alternative. Nitrogen is not a complete replacement for CO2, as the gases behave differently in brewing. However, it excels in areas like purging tanks and blanketing during packaging, where high volumes of CO2 are typically used. By integrating nitrogen into their processes, breweries can:

Reduce CO2 costs.
Ensure consistent operations during supply disruptions.
Lower their carbon footprint.

How does nitrogen compare to CO2?

Nitrogen offers several advantages over CO2:

Cost-effective: On-site generation reduces reliance on external suppliers.
Eco-friendly: Produces fewer emissions, supporting sustainability goals.
Readily available: Eliminates dependency on fluctuating CO2 markets.

However, nitrogen is less soluble in beer than CO2, which affects carbonation and flavor. For certain applications, a blend of CO2 and nitrogen may still be necessary.

Choosing the right nitrogen generator for your brewery

The N2GEN-FLEX is ideal for breweries requiring high-purity nitrogen. It uses PSA technology to produce ultra-pure nitrogen with low operational costs. For smaller breweries, membrane-based systems may suffice, but for maximum efficiency and versatility, PSA generators like the N2GEN-FLEX are the gold standard.

Why brewers should consider the N2GEN-FLEX

The N2GEN-FLEX addresses critical challenges faced by brewers today, from CO2 shortages to rising operational costs. By providing an efficient and reliable nitrogen supply, it empowers breweries to innovate and adapt while improving sustainability. With its cutting-edge technology and brewery-focused features, the N2GEN-FLEX is a must-have for brewers looking to stay ahead in a competitive market.
