Abstract: A modular humidifier system includes a base module having a frame and a wet-pack assembly, the wet-pack assembly being enclosed in the frame. The humidifier system also includes a fan module structured to draw air through the base module and a cover assembly structured to couple to each of the fan module and the base module. The frame includes a first side and a second side, where the fan module is structured to selectively couple to either the first side or the second side.

Abstract: A wet-pack assembly includes a water panel, a scale control configured to surround the water panel on at least three sides, and a distribution tray disposed on a top portion of the water panel and coupled to the scale control via one or more joints. The one or more joints prevent separation of the distribution tray from the scale control. The wet-pack assembly also includes a feed tube extending from a basin formed within the scale control to the distribution tray, where the feed tube is structured to direct water flow from the basin to the distribution tray for recirculation to the water panel.

Abstract: A distribution tray for a humidifier includes a surface, and a flow divider disposed on the surface, where the flow divider is configured to receive a flow of water. The distribution tray also includes a plurality of channels, where each channel within the plurality of channels is fluidly coupled to the flow divider and is configured to receive water from the flow divider. Each channel of the plurality of channels defines a flow path, and each flow path has a varying slope along a length of each channel.

Abstract: A humidifying system includes a water panel, and a distribution tray, where the distribution tray provides water to the water panel. The system includes at least one eductor fluidly coupled to the distribution tray and a scale control tray. The system also includes a valve assembly fluidly coupled to a water supply at a first inlet and is fluidly coupled to the at least one eductor via an outlet, where the valve assembly controls water flow through the at least one eductor. The valve assembly includes a second inlet in fluid communication with the scale control tray, where a wastewater flow from the scale control tray through the second inlet is controlled by a first valve and a freshwater flow from the water supply through the first inlet is controlled by a second valve. A configuration of the first valve is based on an operational state of the second valve.
