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.

Abstract: A pump may generally include a frame including a reservoir. The reservoir stores a hydraulic fluid. The pump may also include a motor assembly supported by the frame and a pump assembly operably driven by the motor assembly. The pump assembly is in fluid communication with the reservoir and configured to dispense the hydraulic fluid out of the frame. The pump assembly includes a first piston and a second piston, wherein the first piston dispenses hydraulic fluid out of the frame between a first pressure and a second pressure greater than the first pressure, and the second piston dispenses hydraulic fluid out of the frame between the first pressure and a third pressure, the third pressure being greater than the second pressure.

Abstract: A system and method is provided for monitoring a hydraulic power system having at least one light emitter and a button. The method includes powering on the hydraulic power system, receiving an actuation at the button and detecting a release of the button after a first time interval, and entering a diagnostic state. The method further includes retrieving a code and displaying the code by turning on the emitter in a first pattern. In some embodiments, a system and method is provided for regulating a temperature of a hydraulic power system. In some embodiments, a system and method is provided for controlling operation of a hydraulic torque wrench.
