If you have been struggling to find a suitable substitute for CO₂, the Nitrobrew could be the perfect choice. Arranged on a convenient skid-mount base that can be easily transported and forked onto your site, the Nitrobrew delivers a cost-effective and reliable supply of on-site nitrogen gas. Enquire about this product ## Product Enquiry How it works + Nitrogen (N₂) is an inert gas that is used to displace oxygen – a common cause of premature food spoilage. Nitrogen has the ability to extend the shelf life of food and beverages while helping to maintain distinct flavours, aroma and appearance. The Nitrobrew has been developed specifically for use in breweries. It converts the air that we breathe into a very pure supply of nitrogen gas that can be used for anything from packaging, to dispensing systems.  This packaged nitrogen generator unit includes an air compressor, refrigerated dryer, filtration system, and a PSA nitrogen generator system. All combined into a single turnkey solution, the Nitrobrew delivers a cost-effective and reliable supply of on-site nitrogen gas. Already pre-commissioned, simply plug it in and you're ready-to-go. ## How the Nitrobrew works All components of the Nitrobrew work in unison to deliver a pure supply of nitrogen gas for your brewery.  1. **Compressed air supply:** A permanent magnet rotary screw air compressor first produces an efficient compressed air supply which is regulated by speed control, to match the changing user consumption. 2. **Filtration: **The compressed air passes through a refrigerated dryer via a pre-filter, which separates out the moisture. The compressed air then passes through coalescing filters to separate out all unwanted oil and particle contaminants down to 0.01 microns. 3. **Nitrogen generation: **This very dry and clean compressed air is then supplied to the nitrogen generator which uses Pressure Swing Absorption (PSA) technology to remove unwanted oxygen and gaseous contaminants, by passing it through a Carbon Molecular Sieve (CMS). The contaminant gases are vented out to the atmosphere and the now pure nitrogen gas supply passes through a storage vessel before being discharged for use at site.   Benefits of the Nitrobrew + The Nitrobrew nitrogen generator system brings many benefits over conventional bottled gas. Cost savings It costs less than one-tenth of the price that gas companies charge, for rented gas bottles. With guaranteed and budgetable operating costs, the Nitrobrew ensures that you're in control of your nitrogen gas spend. Convenience With your own nitrogen gas now produced on-site, the Nitrobrew cuts out the middle man. You'll no longer experience logistical issues and delays that are all too common, when relying on gas bottles that need to be delivered. Constant N₂ supply The Nitrobrew ensures you have a constant, on-tap supply of nitrogen gas 24/7, 365 days a year. You'll be left with peace of mind knowing you no longer have to worry about supply issues. Gas purity Pure nitrogen gas supply is important for any business that operates in the food and beverage industry. The Nitrobrew ensures no contaminants, resulting in pure nitrogen gas for all brewing needs. Variable-speed control The fully packaged Nitrobrew also includes variable speed control for the highest efficiency and lowest running (gas) costs, plus two PLC controllers with operational alarms, and an automated condensate management system. Frees up production space Measuring only 1200 x 2400mm and standing 2000mm high, this unit is small enough to be tucked away into any brewery corner. Or to save production space, simply place the Nitrobrew outside under a covered shelter. Nitrogen (N₂) is an inert gas that is used to displace oxygen – a common cause of premature food spoilage.
