Pure nitrogen for perfect beer: how Dalgakiran Compressor Ukraine LLC installed a state-of-the-art nitrogen generation system for a brewery

In modern brewing, the stability of production processes and the uncompromising quality of the final product are the key factors for success in the market. However, many breweries—from local craft brewers to large-scale facilities—still face significant operational challenges when using purchased nitrogen. Purchasing gas in cylinders or in liquid form entails constant risks: delivery delays, price fluctuations, complex logistics, regular transportation costs, and a high probability of forced downtime on the bottling line.

The optimal solution to this dependency is to switch to on-site gas generation. A professional turnkey engineering solution from “Dalgakiran Compressor Ukraine” allows companies to fully meet their gas needs through in-house production, ensuring complete autonomy and a significant reduction in production costs.

Autonomous nitrogen production: watch our video overview of the project

To see exactly how the gas generation process works and what a fully installed and operational nitrogen station looks like right on the brewery’s production site, watch our detailed video overview:

PSA technology and plant configuration: how a modern itrogen station works

At the heart of the implemented project is a highly efficient nitrogen generator based on PSA (Pressure Swing Adsorption) technology from the leading Turkish manufacturer Ideal Makina.

Operating principle and the role of carbon molecular sieves (CMS)

Extracting nitrogen from atmospheric air is based on the physical separation of molecules under pressure. The key element of the system is carbon molecular sieves (CMS). Thanks to their porous structure, the sieves trap oxygen molecules and other impurities, allowing only nitrogen molecules to pass through. The adsorption process occurs cyclically in the generator’s two columns: while oxygen is adsorbed under pressure in one column, desorption (regeneration of the sieves by releasing pressure) takes place in the other.

Comprehensive configuration of a nitrogen station

To produce high-purity gas, a generator alone is not sufficient. Specialists at “Dalgakiran Compressor Ukraine” design comprehensive engineering solutions consisting of several interconnected process units:

Screw compressor: ensures a stable supply of compressed air at the required pressure and volume.

Air treatment and purification system: includes a water separator, main filters for coarse and fine purification, a carbon column (to remove oil vapors), and a compressed air dryer.

This is critically important, as moisture or residual compressor oil entering the generator can irreversibly damage the expensive molecular sieve.

Air receiver: stores compressed air to smooth out pressure fluctuations before it is fed to the generator.

Ideal Makina nitrogen generator: performs the final gas separation.

Nitrogen receiver: serves as a buffer to store the finished product before it is fed into the brewery’s production line.

The station operates in fully automatic mode 24/7. An integrated sensor system continuously monitors the specified nitrogen purity (up to 99.999%), ensuring that only impeccably pure gas is supplied for production needs.

The role of nitrogen in brewing: why it is critical to beer quality

The use of food-grade nitrogen in brewing has a significant technological impact on the final properties of the beverage: Preventing Oxidation (Tank Flushing): Before filling tanks, kegs, or bottles with beer, they are thoroughly flushed with nitrogen. Displacing oxygen minimizes oxidation of the beer, allowing it to retain its original aroma, color, and freshness for much longer.

Transporting the beer: Brewers use excess nitrogen pressure to transfer (push) beer between containers. Unlike carbon dioxide, nitrogen is practically insoluble in beer under standard transportation conditions, which helps prevent unwanted excessive carbonation of the beer.

Creating the “avalanche effect” (nitro beers): For dark ales and stouts, nitrogen is an indispensable ingredient in the bottling process. Saturating beer with a gas mixture high in nitrogen produces that famous “avalanche effect” and creates an exceptionally dense, stable, creamy head.

Modernization Results: Economic and Technological Benefits for the Business.

Implementing an in-house nitrogen station based on Ideal Makina equipment provides the company with immediate competitive advantages: Complete energy independence and operational autonomy: The brewery is no longer dependent on third-party inert gas suppliers’ schedules, cylinder availability in stock, or traffic conditions.

Production modernization and cost optimization: In-house nitrogen generation reduces the cost per cubic meter of gas by up to 80% compared to purchasing it in cylinders. The project typically pays for itself in 12 to 24 months, depending on the scale of production.

Consistent quality and safety: High levels of automation and a built-in gas analyzer ensure consistent nitrogen purity without the risk of human error.
