IF one drop of oil can contaminate 100 litres of fresh water, just imagine the potential harm that the ingress of oil vapours during food and beverage processing can cause to equipment, systems and end-products, says Integrated Air Solutions’ regional sales manager, Daryn Jack. “The food and beverage industry subsequently depends on superior quality, 100% oil-free compressed air to eliminate the presence of unwanted oil vapour throughout the production line.”
Compressed air specialist, Integrated Air Solutions, is the exclusive regional sales and service partner for global air compressor manufacturing giant, ELGi. Renowned for its quality AB and OF oil-free compressor series, ELGi is one of the few compressor companies able to design and manufacture oil-free air-ends, owing to the organisation’s in-house oil-free technology.
Nitrogen blanketing and bottling are two primary oil-free compressed air applications in the winery, brewery and distillery sectors. ELGi’s AB and OF series are used by some of the world’s leading wine-producing countries including France which ranks second globally. At one of the country’s largest privately-owned wineries, two ELGi AB series units produce certified Class Zero 100% oil-free compressed air to support the sustainable production of over 800,000 bottles of premium organic wine. The unmatched air quality and consistency of the AB series, which meet ISO 8573-1 Class Zero oil standards and ISO8573-7 compliance norms, ensure zero traces of microbial contaminants in the wine.
The AB oil-free compressors are also highly favoured in India where numerous machines have been installed in several breweries and distilleries around the country with five units operating at one of India’s leading alcohol beverage manufacturing companies.
Jack points out that alongside the need for quality oil-free compressed air, end-users also, equally importantly, require reliable air delivery to ensure maximum plant uptime and uninterrupted production for ultimate business sustainability and profitability. “Heeding this call, ELGi has synergised Class Zero ISO 8573-1 with uptime assurance in the design and engineering of its oil-free AB and OF compressor series to offer a dual compressed air advantage to customers and end-users.”
First addressing 100% oil-free air quality, Jack explains that the materials and processes employed within the entire air and water paths of these compressors are approved for food-grade applications. “A food-grade coating is applied wherever air gets in contact with internal metal surfaces for consistent oil-free air delivery without metal debris, while multiple sealing solutions further ensure 100% security against oil entering the chamber.” Jack adds that pipes also feature a special e-coating.
The philosophy of uptime assurance is embodied in every component in the oil-free ELGi machine – from design and manufacturing to quality testing. Quality manufacturing materials and optimised rotor clearances ensure ruggedness and long life under wide ambient conditions underpinning reliable oil-free air delivery for uninterrupted and seamless productivity.
Additionally, stainless steel rotors and hard anodised aluminium housings with stainless steel inserts in the bearing location, help to eliminate corrosion. Stainless steel oil tubing further enhances reliability and non-contact of the rotors extends air-end life.
