Abstract: A coalescing removal separator includes a separator tank and a coalescing media. The separator tank has a separator input that receives a fluid flowing through an HVAC system having entrained gas and solid particles, has a tank wall that forms a volume/chamber inside the separator tank to process the fluid, and has a separator output that provides processed fluid having at least some, most or substantially all of the entrained gas and solid particles removed. The coalescing media is arranged in the volume/chamber of the separator tank, has a series of vertically aligned corrugated perforated sheets substantially filling the volume/chamber of the separator tank and removes the at least some, most or substantially all of the entrained gas and solid particles from the fluid.

Abstract: A spiral heat exchanger features first spiral channels configured to form rows and columns of coiled hot fluid pathways to receive hot fluid; and second spiral channels configured to form corresponding rows and columns of coiled cold fluid pathways to receive cold fluid having a temperature less than the hot fluid. The first spiral channels and the second spiral channels are configured to alternate every other row and column so as to form a matrix of alternating rows and columns of coiled hot and cold fluid pathways separated by alternating coiled walls that act as both fluid separators and conduits through which heat is transferred between the hot fluid and cold fluid.

Abstract: A condition monitoring device for monitoring machinery includes a combination of on-board sensors and a condition monitoring module. The on-board sensors include modules for non-contact temperature, magnetic flux and 3-axis vibration sensing of the machinery. The condition monitoring module provides a condition monitoring signal containing information about an operating condition of the machinery, based upon a data synthesis condition monitoring technique that synthesizes non-contact temperature, magnetic flux and 3-axis vibration sensed data received from the combination of on-board sensors, determines a current operating condition of the machinery, and compares the current operating condition and the baseline operating condition of the machinery.

Abstract: A pump controller features a signal processor configured to respond to signaling containing information about three corresponding discrete arrays with respect to a discrete motor speed for each system position at a motor speed derived from 3D discrete distribution surfaces of motor power, pump differential pressure and flow rate by respective numerical interpolations; and determine corresponding signaling containing information to control a pump, or pumps in a system of pumps, or a system of pumps based upon a corresponding pump differential pressure and flow rate at the motor speed for a corresponding power reading value determined using a numerical interpolation of the three corresponding discrete arrays, the signaling received. The signal processor is configured to provide the corresponding signaling as control signaling to control the pump, or the pumps in the system of pumps, or the system of pumps.

Abstract: A suction diffuser or arrangement is provided featuring a main suction diffuser body and a flow conditioning arrangement. The main suction diffuser body is configured with an inlet to receive an incoming fluid flow, an interior cavity to receive the incoming fluid from the inlet, and an outlet to receive the incoming fluid from the interior cavity and provide an outgoing fluid. The flow conditioning arrangement is configured in relation to the inlet and also comprises a flow conditioning portion having at least one inwardly contoured surface, configured to extend into the interior cavity, diffuse the incoming fluid passing from the inlet into the interior cavity, and provide a flow conditioning that produces a uniform flow of the outgoing fluid by directing the incoming fluid towards the outlet, based at least partly on a contoured design corresponding to the at least one inwardly contoured surface.
