Abstract: This invention is an integrated system comprised of a flat plate, air-to-air heat exchanger, ducting and controls, and an AZFlow™ direct evaporative cooler in configurations where the system is able to provide air that has been cooled well below the ambient wet-bulb to temperatures approaching the dew point. These include: A) a two stage cooler where one evaporative cooler performs the stage one cooling by direct evaporative cooling, of the ambient air.

Abstract: An evaporative cooler, including one or more media, distributes water from a source of water to each media through a constant flow valve. A distribution unit at each media includes a pair of spray bars for spraying water through two rows of uniformly spaced apertures disposed in each spray bar. A spray bar channel associated with each spray bar distributes the streams of water impinging thereupon from one row of apertures to the underlying media in specific locations. A distribution cap associated with each spray bar distributes streams of water impinging thereupon to the front and back edges of the underlying media. The water dripping from the media is drained. A fan or other air moving device draws air through the media to obtain cooled air resulting from evaporation of water flowing downwardly along the media.

Abstract: An evaporative cooler includes an arrangement of a combination of fluid components including flow control valves, spray bars, spray bar orifices, spray bar distribution channels, and distribution caps that produce a water application profile on the media that is adjusted to match the heat load introduced to the media by the air to be evaporatively cooled. The water evaporation rate is a direct function of this heat load profile. Applying water in this profile takes advantage of the wicking rate and flow through time constant of evaporative cooling media to effectively distribute the water through the media. This results in a once through system that allows the volume of water being applied be the lowered such that water not evaporated and exiting the media is limited and does so at very high cycles of concentration while maintaining high levels of cooling effectiveness and scale free media.

Abstract: An evaporative cooler, including one or more media modules, distributes water from a source of water to each module through a constant flow valve. A distribution unit at each media module includes a spray bar for spraying water through a plurality of uniformly spaced holes having an aggregate area equivalent to or less than twenty five percent (25%) of the internal cross sectional area of the spray bar. A distribution cap distributes the streams of water to the underlying media module(s) and the water dripping from the media module(s) is drained. A fan or other air moving device draws air through the media module(s) to obtain cooled air resulting from evaporation of water flowing downwardly along the media module(s).

Abstract: A method for manufacturing a modular starting gate. The modules making up the starting gate include a truss module, a door releasing module, a stall divider module, a front door module, a rear door module, a towing module, and a wheel assembly module. Each module is manufactured to precise tolerances using fixtures or jigs to achieve the desired tolerances. The door releasing module is coupled to the truss module. The truss module is raised mounted to the towing module and the wheel assembly module. A first stall divider module is attached to the truss module and a positioning fixture is used to properly align a second stall divider module relative to the first stall divider module. The second stall divider module is attached to the truss module. The positioning fixture is removed and the front and back gate modules are fastened to the stall divider modules.

Abstract: A modular starting gate having a truss module, a door releasing module, a stall divider module, a front door module, a rear door module, a towing module, and a wheel assembly module. The door releasing module includes a roll-bar having articulated members that are coupled to the front door module via a coupling bar and a turnbuckle adjuster. The roll-bar is coupled to the truss module via a bearing and includes a first section coupled to a second section via a U-joint. A rebound stop is coupled to the starting gate, wherein the rebound stop has a first portion mounted to the front door module which cooperates with a second portion coupled to the stall divider module.

Abstract: A portable stage, transportable in a stacked configuration on a conventional truck trailer, has two modular units manually or vehicularly positionable side-by-side to define the platform of the stage. The platform of one unit is laterally and angularly relocatable relative to the supporting frame to position it contactingly adjacent the platform of the other unit. A plurality of carts, nestable as pairs intermediate the stacked units during transport, are deployed to convey the equipment used on the stage from a source or depot to the assembled stage and return. A pair of ramps serve multiple functions of loading and unloading the units and the carts and are configured to be anchored to different load bearing receiving elements. A specifically configured detachably attached yoke permits turning of pivotally mounted paired wheel trucks while positioning a unit to assemble or disassemble the stage.
