The invention relates to a coating system, especially a low pressure plasma coating system, with at least one treatment chamber and a coating tool, especially a plasma spraying device, wherein at least one pump is provided for evacuation of the treatment chamber, which treatment chamber is formed to be temperature controllable. In addition there is a coating method for low pressure plasma coating with a temperature controlled and evacuated treatment chamber, in which a workpiece is coated by means of at least one coating tool. For acceleration of the coating process, especially the evacuating of the treatment chamber, it is proposed that at least the walls of the treatment chamber and/or the inside of the treatment chamber are temperature controlled at a temperature between 45° C. and 75° C.
