Optimal illumination of the polymerization chamber with four compact fluorescent UVA lamps emitting in the 350-400 nm range. Rapid curing through special arrangement of the powerful fluorescent lamps and reflectors. Homogenous curing within 0-15 minutes with an exposure time preset and automatic shut-off facility controlled by mechanical timer. Large polymerization chamber to accommodate up to four models at one time. Straightforward operation, thanks to removable insert and only turn on the main switch and setting the timer for polymerization. High level of safety, thanks to well-insulated electronics complying with relevant standards. Small space requirement, thanks to compact design.
