envelope of operation on the 48 Series rooftop unit to meet year round com-fort and energy conditions. Designed with energy savings in mind. Energy recovery wheels rotate between the incoming outdoor airstream and the building exhaust stream. As the wheel ro-tates, it transfers heat and moisture from one airstream to the other. Resulting in

Abstract. In this chapter, the fundamentals of design of conveying and construction machinery will be presented. Machines that fulfill transportation tasks in limited operating areas such as mines, ports, work and storage yards, as well as construction sites are most common and can be found in any type of industry.

transfer stations and a second day of public meetings. Based upon these two fact-finding sessions, the Working Group in March 2000 published the draft report, A Regulatory Strategy for Siting and Operating Waste Transfer Stations. This report made several recommen-dations to EPA concerning proper and equi-table siting and operation of transfer
