Abstract: A vaneaxial blower system having a stator and a rotor is disclosed. Each of the stator and rotor have a hub and blades, each of the blades have a leading edge and a trailing edge, an angle theta defined by a line extending from the respective leading edges to the respective trailing edges and the respective hub and an angle beta defined as an angle measured between a camber line between a first blade and a second blade and a horizontal tangential line that extends through respective leading edges of the first and second blade.

Abstract: An improved double-wall heat exchanger in which the safety “leak” space between heat exchange surfaces forming channels for the fluids exchanging heat is filled with a heat transfer medium with improved thermal conductivity in comparison to air. Pressure responsive rupture points allow release of the heat transfer medium and the heat exchange fluid in the event of failure of one of the containment surfaces. Metal-to-metal heat transfer points are dispersed in the gap to further enhance heat transfer between the hot and cold heat exchange fluid streams.

Abstract: A process device includes a controller, a wireless communications module. The wireless communications module is coupled to the controller. A power generation module is provided to generate electricity for the process device. The power generator module can be disposed within the process device or it can be a separate unit coupled to the process device.
