Small drying unit for coatings on substrates, such as ink on paper in home or office, comprises near infrared source with cooled reflector and safety casing

摘要

An near infra red source (13) emits wavelengths of 0.8-1.5 mu m, and has a concentrating reflector (15) with cooling fins (17) to dry the coating. A lightweight plastic casing (7) covers the reflector, and can be touched without causing a burn.
