A rotary-screw air compressor has a separator, a cooler fan assembly, and a mounting apparatus. The separator has a first chamber and a second chamber. The first chamber separates compressed air and coolant. The second chamber separates compressed air and moisture. The separator is disposed in a chasm formed by a first platform. The mounting apparatus elevates a motor and air end vertically above and spatially apart from the separator. A cooler fan assembly is vertically above the motor and air end. The cooler fan assembly has a first heat exchanger vertically above a second heat exchanger. A shroud having an opposite open end is connected to the first heat exchanger at one open end and the shroud is connected to the second heat exchanger at the other open end. A cooler fan is disposed completely within the shroud and between the first and second heat exchangers.

Rotary Seals are suitable for a wide range of temperature and pressure/velocity applications. Seal solutions include flange seal, insert seals and seals with metal locking devices. They feature high performance material, metal retaining ring designs and memory lip designs. Rotary Seals are designed to seal dynamic rotating motions. Some rotary seals are designed for dry-run, including rotary shaft seals and radial lip seals.

Rotary selector valve is a multi-port valve usually provided with 2-8 ports. This valve can be used as quiet replacement for solenoid valves. It internally supports a rotatable trunnion having an elbow passage between a nozzle portion of the trunnion and a lower end outlet that communicates with a test port of the valve body. The outer end of the nozzle has an axially reciprocable hollow seal piston with a seal support ring whose outer face is formed with an endless groove to receive an O-ring. It can control the communication of a plurality of conduits with an outlet opening into a chamber of a stationary valve casing. It can be used in installations for the detection of fuel-element-casing failure or whenever variable communications between a certain numbers of inlet passageways traversed by a fluid and one or more outlet passageways are desired.

Rotary separator turbine uses unique technology to separate oil, water and gas, while offering the opportunity to recover energy lost in conventional pressure letdown operations. A rotary-separator turbine is built with full flow capacity for a 500 F downhole temperature with 850,000 lbm/hr production rate. The preliminary design is for the 10-megawatt wellhead power plant for the Roosevelt type resource. This system shows a specific power of .0013 kW hr per lbm, which is 20 percent greater than an optimized wellhead single stage flash plant. This is 26 percent greater than a central plant of 20 to 50 MW capacity when consideration is given to steam-gathering system pressure drop between the wells and central plant.
