Abstract: In general terms the present disclosure proposes a lamp arrangement for curing a material, the lamp arrangement including at least one lamp unit, wherein each of the at least one lamp unit has at least one light source configured to emit a radiation of a pre-defined intensity, and at least one reflector; and a controller configured to control at least one parameter to provide the desired curing of the material.

Abstract: The present invention relates to a device at distillers adapted to distil solvents for recovery of pure solvent from impure solvent, said solvent (2) being used e.g. for washing away residues of paint from spray guns. The distiller (1) comprises an outer container (5) with a boiling chamber (8) which at the top has an opening (9) which can be tightly closed by means of a cover (10) and a flexible inner container (13) is provided in the boiling chamber (8), said flexible inner container (13) containing impure solvent (2) to be distilled. A pipe means (20) is placed beside the flexible inner container (13) in order to allow solvent steam (7a), which is generated by boiling solvent in a lower space (19) beneath the flexible inner container (13), to pass from said lower space (19) into an upper space (16) having an outlet (17) and located above the flexible inner container (13) for preventing said solvent steam (7a) from lifting the flexible inner container (13) in the boiling chamber (8).
