As we have mentioned in previous blogs the food and drink industry relies heavily on compressed air for a variety of manufacturing operations. To ensure best practice, the International Standards Organisation (ISO) has a specific class of air quality for sensitive industries such as food and beverage. Known as Class zero, it is the most stringent air quality class, limiting oil contamination in liquids, aerosols, and vapours.
Compair’s new Ultima compressor range are 100% oil and silicone-free and meet ISO 8573-1 Class Zero (2010), making them the ideal choice for stringent oil-free applications within food and beverage, pharmaceutical, electronic and the automotive industries.
What makes this compressor series unique is the lack of a gearbox. Ultima uses ultra high efficiency direct drive motors which replace the gearbox and the single motor, which optimise performance throughout the complete volume range, as the airends can be driven at different speeds dependant on the demand. With a single motor driving both airends together this is not possible.
The Ultima utilises an intelligent “digital gearbox” design, which continuously monitors and independently adjust the speeds of each airend, ensuring maximum efficiency and pressure ratios at all times. When any regulated speed compressor gets to the minimum speed, it goes into idle run. For any compressor, this is wasted energy. Ultima uses 45% less energy in idle run than a conventional two-stage compressor and a 160kW compressor uses only 8 kW in idle run.
Ultima contributes to bottom line cost savings in many ways. Not only do these compressors deliver outstanding efficiency and significantly lower lifecycle costs, the Ultima requires on average up to 37% less floor space than a conventional two-stage oil-free compressor. This allows easy installation in the smallest possible space giving you an oil free compressor option in smaller production facilities with limited space.
In the industries that require Class Zero air the Ultima is the future of oil-free compressor design, available today. Harrier Pneumatics engineers can work with you to install the necessary equipment to help you ensure compliance with your particular industry’s regulations and put in place a regime of regular ongoing testing.
