Wall Duct Application
Product Description
Wall duct is a UL® Listed, metal raceway used to enclose the wiring to diagnostic-imaging machines. Wall duct is used in combination with trench duct to provide a complete raceway system from the power and control consoles to the patient table. The raceway system enables a complete lay-in system. Cables can be installed by removing all covers and laying in the conductors. This is an important advantage due to the large diameter connectors used on the high voltage power cables. Whether these connectors are installed on the cable after “fishing and pulling” or factory-assembled into one customized unit, a lay-in system is necessary. Branch connection from the system is accomplished by pipe-nippling out of the covers or sides of the duct, or by removing sections of covers.
Each section of wall duct is furnished with covers. Customer selected variations can be flush or surface-mounted. Most applications will require a combination of each. The transition from one type to the other is accomplished by the use of a flush-to-surface device. The normal application has flush-mounted vertical duct connecting to a surface-mounted horizontal duct in the control rooms.
Economy and Flexibility
Economy and flexibility are the keys to comparing wall duct and cable-conduit systems. Conduit installations are fixed location systems. Wall duct, with its continuous covers, provides removable points of access. Modifications can be made to the room and equipment lay-out utilizing the existing wall duct locations, reflecting the superior flexibility of the wall duct as compared to conduit. With the continuing advances in medical-imaging technology, wall duct installations serve well during economical changes.
