Such a flameproof enclosure may be considered as a building stone of a modular energy distribution system containing extensive low voltage installations (Fig. 6.102) in a chemical plant. [Pg.266]

A hot runner system is required for conserving material and reducing the amount of rework required. Externally heated hot runner systems are always preferable to the internally heated systems as the externally heated hot runner systems maintain uniform flow of melted material with a constant melt temperature over the cross-section of the hot runner. The heat energy can be evenly distributed from outside to inside in the melt. Low voltage systems (5 or 24V) have been observed to function well. [Pg.326]

Continuous water irradiation by e-beam is conducted on a bench scale at the Austrian Research Center, Seibersdorf. A 500-keV, 25-mA ICT accelerator (Vivirad-Eligh Voltage Corp.) is used as the electron source [52]. A 3-mm horizontal layer of water is irradiated. Low penetration by the lower energy electrons produced by this smaller accelerator is compensated for by irradiating a turbulent water flow. Dose distribution in the turbulent stream is not uniform, but the overall volume of water treated to an average dose is increased. A schematic of the system is shown in Fig. 5. [Pg.339]
