Abstract: A fluid compression system includes a compressor operable to produce a first flow of compressed fluid and a refrigerated dryer coupled to the compressor and operable to separate the first flow of compressed fluid into a second flow of compressed fluid and a flow of liquid. A first sensor is positioned to measure a property of the second flow of compressed fluid, and a controller is operable to initiate operation of the refrigerated dryer at a first time and at least partially in response to the measured property, and to initiate operation of the compressor at a second time. The first time is before the second time.

Abstract: A gas compression system is operable to deliver a flow of compressed gas to a point of use. The gas compression system includes a compressor that is operable to produce a flow of compressed gas at a first pressure, a motor operable to drive the compressor at a compressor speed, and a gas treatment member positioned to receive the flow of compressed gas from the compressor and deliver the flow of compressed gas to the point of use at a second pressure. A controller is operable to vary the compressor speed in response to a difference between the first pressure and the second pressure.

Abstract: A method and system for modifying the operation a device. The method can include obtaining a first reconfiguration kit. The first reconfiguration kit can include a portable memory device. The method can also include connecting the portable memory device to the device and transmitting information between the portable memory device and the device. The method can further include disconnecting the portable memory device from the device and returning the portable memory device to an entity associated with the provider of the portable memory device.
