A dehumidification forward passage is provided for guiding air withdrawn from a treating chamber as dehumidification-subject air A″ to an adsorption area of an adsorption/desorption type dehumidifying device. A dehumidification return passage is provided for guiding air A″ past through the adsorption area to the treating chamber. A desorption heat pump is provided for heating desorbing air HA to be flown through a desorption area of adsorption/desorption type dehumidifying device, with utilizing, as a heat sink, dehumidified air A″ which has flown through the adsorption area and sent to the dehumidification return passage. There is provided a sensible-heat heat exchanger configured to cool the dehumidification-subject air A″ present in the dehumidification forward passage through a heat exchange reaction with dehumidified air A″ present in the dehumidification return passage which has been cooled via absorption of its heat by the desorption heat pump.

A method and system for powder coating non electrically conductive elements, preferably brake pads. A pre-treatment station is upstream of an electrostatic powder coating deposition station and a baking station for melting and polymerizing the powder coating in order to form a coating layer on a surface to be coated. The pre-treatment station causes the elements to be coated to conduct electrically by uniformly wetting said elements by means of creating poorly mineralized water covalent bonds on at least one surface to be coated, in an amount aimed at producing a measurable weight increase in the non electrically conductive elements, which then causes them to conduct electrically. The water adsorbed and/or deposited is subsequently eliminated within the baking station.
