For example, a 300 mbar reduction in differential pressure over 8000 operating hours can save approximately £5650 per UltraPleat filter annually. To maximise the efficiency of UltraPleat technology, flowoptimised filter housings and continuous monitoring through an economizer are essential. This system not only indicates the most economical replacement time for filters but also provides data for higher-level control of compressed air systems. For larger compressed air volumes, UltraPleat filters ensure a prolonged service life with consistently low differential pressure, vital for achieving energy savings. Donaldson’s Ultrapac Smart adsorption dryer technology incorporates these filters, along with capacity control and compressor couplings, contributing to substantial savings in regeneration air. Additionally, energy-efficient dryer technologies, such as prefilters with electronic, level-controlled drains, zero purge technology, and energy-saving control systems, enhance overall efficiency. Addressing air leaks Even the best filter technology cannot compensate for system leaks. Common sources of leaks include pipe connections, conditioning units, shut-off valves, quick couplers, and terminal equipment. These small leaks can cumulatively lead to significant losses. For instance, a company operating a 150 kW compressor for 6000 hours a year can waste nearly £50,000 annually due to leaks. Detecting and addressing leaks requires regular servicing and preventive maintenance. Donaldson offers advanced technology and techniques to help customers detect and minimise energy costs, including Air Quality Audits. Its experienced customer service engineers can identify even the smallest leaks while the plant operates normally, providing detailed reports and tailored optimisation concepts. Optimising compressed air systems can significantly reduce energy consumption and costs while also contributing to environmental sustainability. Implementing advanced filtration technologies and efficiency improvements showcases the potential for substantial savings and enhanced performance in various industries.
