Energy Consumption: How it Relates to Performance in Refrigerated Compressed Air Dryers Timothy J. Fox | Research and Development, SPX Those in charge of specifying and purchasing equipment for industrial compressed air systems have many decisions to make. The design of a proper compressed air system does not end after determining the quantity of air required (i.e., the air compressor and receiver tank); the user must also pay particular attention to the quality of the air that his or her process needs. Today’s optimal air systems demand less moisture, less particulates, less oil aerosols, and less oil vapor than ever before. For most users, a refrigerated-type compressed air dryer will satisfy their requirements for moisture removal. With so many manufacturers offering “equivalent products”, each with promises of delivered pressure dew point, pressure drop and consumed electrical power, how does one make an intelligent selection This paper will address power consumption, and how it relates to a refrigerated dryer’s ability to remove moisture. It will explain how a potential buyer can determine if the stated performance is possible with the power consumption that is published in the manufacturer’s literature. an SPX Brand For more information please contact: Hankison.inquiry@dehydration.spx.com or visit our website at www.hankisonintl.com ple201211_SPX_whitePprHLF.indd 1 input #20 at www.plantengineering.com/information 10/29/2012 3:22:28 PM Four Things You Need to Know About Compressed Air Dew Point Sampling Sampling is needed when direct measurement of the air is undesirable or is simply not feasible. This may be due to a high process temperature, the need to protect the sensor from water spikes, the added convenience of installing and removing the instrument from a pressurized process without shutting down the line, or wanting to make the measurement in a more convenient location. To get a representative sample of the process gas and avoid potential sources of errorcaused by incorrect sampling practices, the following aspects should be considered. • Changing the pressure of the gas changes the dew point • To avoid condensation the dew point must be below the ambient temperature in the sampling line • A leak-tight sampling system construction is essential • Sampling in still air should be avoided, however low air flow is okay Download the White Paper at knowledge.vaisala.com/SampleCell www.vaisala.com/compressedair sales@vaisala.com ple201211_whtPprHLF_vaisala.indd 1 input #21 at www.plantengineering.com/information 10/12/2012 10:17:06 AM
Maximize Uptime and Profits Through Effective Fleet Management Practices Pat DeSutter | Director NMHG Fleet Management This paper from Hyster Company discusses lift truck fleet management. From planning and use strategy to understanding total cost of ownership, this white paper helps any operation with a fleet of lift truck equipment to understand how to effectively and efficiently manage that fleet. Topics included in this paper are challenges to fleet management, key elements of fleet management, total cost of ownership, replacement planning, telemetry and outsourcing. One central challenge presented to lift truck fleets is hidden cost. Multiple service providers can add an unexpected financial and administrative burden to the fleet’s operation. With only an estimated 20 percent of an operation’s materials handling costs going to the initial purchase of the lift truck, the remaining 80 percent is composed of maintenance, operator and fuel costs. A proper understanding of total fleet management from purchase to operation helps a company to review all associated costs and asset utilization. Several key element of true fleet management are also outlined, including proper planning, which is essential as lift trucks have an economic life of approximately 10,000 to 12,000 hours as a general rule. While that life varies depending on maintenance practices and operational conditions, it is a reminder to plan not only the usage of the trucks, but also their replacement, to avoid costly downtime or increased maintenance expenses. Hyster’s FleetSmart web-based reporting system allows managers to monitor and measure the fleet’s utilization, specific truck cost per hour and overall operating expenses. After reviewing many of the factors necessary to effectively manage and maintain their fleet, some operations choose to sign agreements with lift truck manufacturers or dealers to provide expertise and management assistance. Capitalizing on years of experience, a strong dealer network and utilization of latest technology, Hyster Fleet Services can deliver unmatched results in reducing costs and maximizing productivity.
