How compressors recover 98% energy at the Swedish Dafgård food plant
Big energy savings, cost reductions, reduced carbon dioxide emissions and air quality improvement: see the difference our oil-free compressor systems make
Food and beverage oil-free air solutions
Dedicated Class 0 certified compressor air systems for the food and beverage industry. Guaranteed oil-free air for safe and high-quality end products, lowest total cost of ownership
The standard in food and beverage air compressors
Whether for sorting and ejecting, mixing, aerating substances, or inflating and stuffing products, compressed air for food and beverage applications must be absolutely clean and free of contamination. Only oil-free compressors can guarantee absolute air purity, and eliminate any chance of air-based contamination.
100% clean, 100% safe
Atlas Copco has set the standard for contamination-free compressed air in the food and beverage industry. You can rely on the largest range of oil free technologies within the industry, knowing that you work with the first compressor manufacturer to achieve ISO 8573-1 (2010) Class 0 clean air, certified by TÜV Rheinland. Food and beverage air produced by our compressors is completely free of oil aerosols and vapors to protect your hard-won reputation.
First to be ISO 22000 certified
When ISO 22000 emerged as the most important global Food & Beverage quality standard, we have become the first compressor manufacturer to be awarded the certification for our Oil-free Air Division production facility in Antwerp, Belgium:
- manufacturing equipment made in a clean, safe environment
- increased transparency with documented Food Safety Management Systems in place
- our experts can contribute towards our customers’ ISO 22000 certification process
At home in the food and beverage industry
Make decades of experience in food and beverage work for you:
- certified technology
first to receive ISO 22000 and ISO 8573-1 (2010) CLASS 0, for all oil-free air compressors - pushing boundaries in performance
first to integrate Variable Speed Drive, oil free screw technology and rotary drum technology - global installed base
Thousands of compressed air installations throughout the world, with many of the world’s largest food and beverage companies
Applications
Automation air
Compressed air is used to control the valves and actuators in automated lines for filling, packaging and bottling. With oil-free compressed air, you prevent your automation components from jamming and keep your end product safe
Transportation
Compressed air is used to push powdered milk or cocoa powder along pipes.
With oil-free air, you will avoid oil contaminant mixing with the powder and maintain the powder purity
Cleaning air
Compressed air for cleaning bottles, packaging and moulding prior to filling. Oil in compressed air will contaminate the food containers and alter the flavour and odour of the end product, besides being a health hazard
Air blowing, aeration
Compressed air is pumped into a liquid to boost its oxygen content. This is used, for example, in fish farming to oxygenate water in lower layers and/or oxidize the sediments. Oil contamination in the air will kill the fish and other fauna
Fermentation
Compressed air supplies oxygen to bacteria during fermentation to produce food ingredients such as citric acid, wine, yoghurt… The presence of even small oil traces will affect bacterial activity, create a substandard product and contaminate the end product
Food storage
In the air separation process, compressed air is broken up into oxygen and nitrogen. The nitrogen is then used to preserve foods in cans, in larger storage facilities and in maritime transport. The air must be 100% oil-free as the nitrogen comes directly into contact with the food. Oil will also destroy the membranes in psa plants which are expensive to replace
Cooling and spraying
Compressed air is used to cool down baked goods after they emerge from the oven. Contamination of the air spoils the end product leading to rejections and production losses
Food and beverage customer stories
How industrial heat recovery lowers your natural gas consumption
German food company Wernsing Feinkost reduces its natural gas consumption and protects our climate with a heat recovery solution in their compressors. See how
Muller Dairy reduces heating costs through energy recovery
Read in this case story how the UK-based Muller Dairy saves in gas process heating costs thanks to their compressor set-up. The secret? Energy recovery technology
Atlas Copco provides oil-free compressed air to La Molisana
Class Zero, means zero oil and zero risk of contamination or of unsafe products. Oil-injected compression, even filtered, cannot guarantee that all oil vapors, aerosols and other contaminants are removed from the air.
In the food and beverages industry in particular any risk of oil contamination must be excluded.
