The Tine Norske Meierier dairy packer in Norway has adopted compressed air filtration that is designed to be energy efficient.
Oil-X Evolution compressed air filters by Parker domnick hunter Filtration use aerospace technology to optimise air flow paths through the filter's housing and element to reduce air turbulence and pressure losses, reducing system operating costs.
"Pneumatic machinery at Tine Norske Meierier does most of the work of slicing, grating and wrapping cheeses and the compressed air driving this machinery must be of the best quality. A new central compressed air system was installed by domnick hunter/Hillevag Elektro Diesel AS and was fitted with a Pneudri desiccant dryer and Oil-X and Bio-X filters to ensure purity and sterility."
"Energy-saving controls on this purification package will save the company more than 100,000 kWh per year in energy consumption, according to Gaute Nesse, the company's maintenance manager," says Mr John Davis, business development manager at Parker domnick hunter Filtration.
The filters have been designed from the outset to meet current and forthcoming requirements for compressed air quality. Design of the compact filter has focused on efficiency-critical areas, such as air flow management, filtration media selection and construction and efficient removal of coalesced liquid.
Aerospace technology has been applied to eliminate all unnecessary pressure losses in the filters. These losses would otherwise consume energy as the pneumatic system worked harder to compensate. Air streams are channelled through the filters in a way that reduces turbulence and pressure losses, including the use of full radius blended bends, diffusers and turning vanes that reduce a 90° inlet corner into a number of smaller, more efficient corners. The filters also employ a flow distributor to ensure the air stream is evenly distributed throughout the filter element for maximum performance.
