Compressed air fail: Poor disposal
A lumber processor installed a remote lubricant-injected rotary screw compressor in an outbuilding to supply compressed air to a debarking system out in the yard. Lubricant injected air compressors normally pass some compressor oil into the system — usually about 4 parts per million for a well-maintained compressor — even though there is an air/oil […]
Kaeser’s new active oil-water separator shown at Hannover Fair
With the intelligent Aquamat i.CF, Kaeser Kompressoren has redefined condensate treatment. Available for delivery volumes up to 90 m³/min, this new oil-water separator now comes equipped for the first time with the Aquamat Control internal controller, which undertakes active management of the process while simplifying maintenance planning and making service work cleaner. Wherever compressed air […]
Compressed air fail: Strange CFM profile
A sawmill maintenance department requested a compressed air assessment to determine the efficiency of its system and to find out if any improvements could be made to reduce their compressed air system operating costs. They called in an auditor who placed data logging equipment to measure pressure, flow, and power. From these measurements, the auditor […]
Rotary screw compressors more efficient than ever
Rotary screw compressors are the dependable backbone of an industrial compressed air supply. With a multitude of features, the innovative CSD/CSDX range from Kaeser Kompressoren fulfills this role more efficiently, dependably, and economically than ever before, while at the same time reducing a company’s CO² footprint. The most important highlight of these compressors is their […]
Compressed air fail: Air dryer robbery
A routine audit of a wood products company has turned up some surprising results on a system that was thought to be very efficient. The system is simple — one compressor, a 100-hp variable speed drive controlled (VSD) screw compressor, and a heatless desiccant air dryer. Data loggers were placed on the system by a […]
Compressed air fail: Two VSDs
A bakery upgraded its aging compressed air system with to new air compressors. The corporate directive was to replace any old equipment with new more efficient types that would help reduce the company’s carbon footprint. As a result, the decision was to purchase variable speed drive (VSD) compressors to reduce compressed air energy consumption. Generally, […]
Compressed air fail: Check valves
A metal products company had a system of multiple compressors arranged in two compressor rooms. The maintenance workers were having constant problems setting up their compressors to run in a logical sequence. For some reason, the main compressor would never turn off in automatic start, which would allow them to save energy. The big compressor […]
Compressed air fail: Remote coolers
A wood products company had issues with its compressor room. Despite installing good filtering, the compressor oil and air coolers would clog up with sawdust — and the compressors would constantly overheat. The maintenance manager, remembering something from one of his previous jobs, decided to move his compressor coolers outdoors. This worked great in the […]
Quality air is critical for aerospace manufacturing
Compressed air quality is crucial for aerospace manufacturing, as aircraft components and tools must be of the highest quality and precision. This demanding standard for component quality urges aerospace manufacturers to utilize compressed air with specific requirements. The air must be clean, dry, and unvaried under pressure. If the air becomes dirty, moist, or varies […]
