An Internet of Things (IoT) gateway integrated into a real-time monitoring system for skid-mounted natural gas compression systems. The IoT gateway enables remote monitoring, troubleshooting, and diagnosing of natural gas compression systems by providing access to cellular and satellite communication networks for communicating operational data to one or more remote servers. The IoT gateway can be configured to select a communication network based on an order of priority and other various criteria. The order of priority and the selection criteria may be updated over the air. The IoT gateway can be further configured to receive and relay software and other updates to one or more components of the natural gas compression system. The IoT gateway is configured to meet various regulatory compliance standards and is explosion proof.

A fan is disclosed. The fan includes a base mountable to a ceiling; a base motor contained in the base; a multi-section shaft operably connected to the base motor and moveable between a collapsed position and an extended position; and a fan assembly connected to the multi-section shaft and including a fan motor and at least one fan blade operably connected to the fan motor, wherein in response to a signal, the base motor raises or lowers the fan assembly by moving the multi-section shaft between the collapsed position and the extended position.

It is provided a cooling fan module having: a fan shroud; a fan propeller cutout, which is formed in the fan shroud; a motor mount which is mechanically connected to the fan shroud by means of struts which are located at the rear viewed in the flow direction; a motor, which is mounted at least partially in the motor mount; a fan propeller which is arranged in the fan propeller cutout and which is driven rotationally about a rotational axis R by the motor. The fan propeller has a plurality of blade elements. All the elements of a group which has at least one of the struts and at least one of the blade elements are forward-sickled or rearward-sickled.

A gaseous compression system for compressing a gas from an initial pressure to an exit pressure with a first, blower compression bank and a second, mechanical compression bank. Each compression bank has plural stages of gaseous compression with a gaseous fluid compressor and a heat pump intercooler. The heat pump intercooler comprises a cascading heat pump intercooler with a high temperature section, a medium temperature section, and a low temperature section, each temperature section with an intercooler core. Each stage of the blower compression bank has a high-pressure blower, and each stage of the mechanical compressor bank has a mechanical compressor. A final stage of gaseous compression is without a heat pump intercooler. Gas compressed by the gaseous fluid compression system can be injected into a gas-driven generator to generate electric power from movement of a working fluid induced by injection of the compressed gas.

The disclosure provides a centrifugal fan, including an enclosure, a spacer, and a fan blade rotor. The enclosure includes a top panel, a bottom panel, and a side wall connected between the bottom panel and the top panel. The top panel, the bottom panel, and the side wall together form a first air exhaust vent and a second air exhaust vent. The spacer is disposed in the enclosure, is connected between the bottom panel and the top panel, and spaces a first space in communication with the first air exhaust vent and a second space in communication with the second air exhaust vent in the enclosure. The spacer includes a first opening. The first opening is in communication with the first space and the second space. The fan blade rotor is rotatably disposed in the second space.

A fan is disclosed. The fan includes a base mountable to a ceiling; a base motor contained in the base; a multi-section shaft operably connected to the base motor and moveable between a collapsed position and an extended position; and a fan assembly connected to the multi-section shaft and including a fan motor and at least one fan blade operably connected to the fan motor, wherein in response to a signal, the base motor raises or lowers the fan assembly by moving the multi-section shaft between the collapsed position and the extended position.

A cooling fan includes a base, a tube, a bearing, a stator, a rotor, and fan blades. The base includes a base protrusion. Each of the fan blades includes a first notch. When the cooling fan is working, the base protrusion passes through the first notch on each of the fan blades. The base protrusion and the first notch not only increase the heat exchange area of the base but break the thermal boundary layer on the base repeatedly to improve the heat dissipating effect when the cooling fan is working.

A blower includes an impeller that is rotatable about a central axis extending in a vertical direction, a motor that rotates the impeller, and a base portion on which the motor is mounted. The impeller includes a cup portion that covers the motor, and blades extending radially outward from the cup portion and arranged in a circumferential direction. A gap is provided between the cup portion and the base portion such that the gap becomes narrower in an outward direction with increasing distance from an interior of the cup portion.

A compressor controller for operating a compressor within an industrial automation environment is provided. The compressor controller includes a control module, configured to control the compressor via control settings, and a machine learning module, coupled with the control module. The machine learning module is configured to receive a set of supervised data related to the compressor, and to train with the supervised data to produce a Newtonian physics model representing the inputs and outputs of the compressor within the industrial automation environment. The machine learning module is also configured to receive performance data related to the compressor, receive environment data related to the compressor, and to process the performance data and environment data to produce predicted future performance data for the compressor, and to produce control settings for the compressor.

A fan includes an electric motor and a fan wheel drivable or driven by the electric motor, arranged within its housing. The underside of the housing has an opening for an electric outlet, and a side the housing has a bracket, thereby forming a bushing. An electric line is arranged at least partially at the underside of the housing and is guided through the bushing, and a cover element is arranged at the underside of the housing. The cover element has a first section and a second section. The cover element is arranged at the underside of the housing in such a way that the first section is at least partially arranged in the bushing and clamps the electric line in the bushing while forming a strain relief, and that the second section covers the opening.
