A thermal control valve for use in a lubricant flooded compressor system including a controller that generates a control signal includes a valve body including a hot coolant inlet, a cooled coolant inlet, a mixed coolant outlet, an actuator space, and a cylinder bore. A sleeve is positioned within the cylinder bore and is movable between a first position, a second position, and a third position, and an electrical actuator is at least partially disposed within the actuator space and is operable in response to the control signal to move the sleeve between the first position, the second position, and the third position.

A dryer assembly for drying compressed fluid received from a fluid compressor. The dryer assembly comprises a compressed fluid circuit and a refrigeration circuit associated with the compressed fluid circuit and configured to reduce the temperature of the compressed fluid and to remove condensate from the compressed fluid. The dryer includes means for manipulating the dryer to regulate the rate of heat transfer between the compressed fluid circuit and the refrigeration circuit. A first sensor senses the lowest temperature of the compressed fluid after the compressed fluid has passed the refrigeration circuit and a second sensor senses a reference temperature. A controller is configured to receive the lowest temperature and reference temperature from the sensors and to determine a relative humidity based on the lowest temperature and the reference temperature. The controller controls the means for manipulating the dryer in response to the determined relative humidity.

A method is provided for determining and for predicting the present and future condition of a machine having at least one rotative element. The method includes an initial step of storing in memory a predetermined logic routine and at least one predetermined key frequency of the at least one rotative element of the machine. The machine is operated in a predetermined operational state and, during operation, the mechanical motion of the at least one rotative element is sensed by at least one sensor. The sensed mechanical motion of the at least one rotative element is converted into a corresponding electrical signal, and the predetermined operational state of the machine is correlated with a corresponding electrical signal. The corresponding electrical signal is inputted into corresponding vibration data by utilizing the predetermined logic routine. Then, the corresponding vibration data is compared with the at least one predetermined key frequency to predict the present and future condition of the machine. A control signal is transmitted to the machine, in order to control the machine, in response to the present condition and the predicted future condition of the machine.

An apparatus includes a compressor for compressing fluid including a sensor capable of sensing at least one function relative to the operation of the compressor. A controller controls the compressor causing the value of said one function to be within a predetermined parameter. A computer overrides the independent response of the controller wherein the controller acts in response to the computer, the computer being separate from said controller. The computer may act as a sequencing computer or as a test computer.

A fluid compression system includes a fluid compression device which pressurizes fluid. A pressure sensor senses pressure generated by the compression device. A control device indicates operating parameters and functions of the compression device, graphically displays the parameters and functions, sets limits of the parameters and controls the compression device in response to any of the parameters reaching a preset level of a corresponding function. A reverse rotation sensor determines when the compression device is operating in an incorrect direction by the initial pressure sensed by the pressure sensor after startup of the compression device, and in response, shuts off the compression device.

A position of a rotary valve having limited motion between an open and a closed position is determined by a limit sensor. A stepper motor supplies power to open and close the rotary valve. A coupling transmits any stepper motor motion to the rotary valve. A sensor actuator is affixed to the coupling. A limit sensor determines the position of the rotary valve by sensing the position of the sensor actuator, wherein there is no contact between the sensor actuator and the limit switch when the position of the rotary valve is being determined.
