REGI U.S., Inc., through its subsidiary, RadMax Technologies, Inc. (RadMax), operates as a technology and product development company.
The company engages in designing, building and proving the functionality of a family of axial vane, rotary engines, compressors, pumps and gas expanders for commercial, residential and government applications.
The company focuses on developing devices that reduce carbon footprint, device size, weight and parts count. Its proprietary sliding axial vane technology enables its devices to deliver high output to weight ratios making them scalable from small to very large. The company focuses on applications that are new and disruptive. The company’s patented RadMax sliding axial vane technology, has vanes that form chambers on both sides of the rotor, the volume of these chambers change as the vanes follows along the cam profile.
Products and Applications
RadMax Compressed Gas Expander
The RadMax compressed gas expander is a positive-displacement device that is uniquely able to capture both kinetic and pressure-volume energy and convert it to rotational power in compressed gas expansion applications. This power could then be used to drive other devices, such as compressors and electrical generators.
Applications
The RadMax gas expander, when paired with a generator could replace less efficient devices, such as the throttling valves in air conditioning and refrigeration systems. The incumbent free gas expansion valves and mechanical throttling valves are not capable of capturing available pressure energy. The RadMax compressed gas expander is also used as the turbine component in the RadMax expander engine, it is used to capture lost energy in natural gas pipelines and throttling stations, and is used to generate electricity from flare gas, solar, and geothermal sources.
The company focuses on designing and building prototype devices targeted for use in the air conditioning / refrigeration and natural gas distribution industries. When used these devices could significantly reduce electric power requirements and associated carbon dioxide emissions. RadMax is partnering with the Department of Energy (DOE) through Pacific Northwest National Laboratory (PNNL) on various Solar Energy Technology Office (SETO), Geothermal Technology Office (GTO), and Building Technology Office grant proposals and projects.
RadMax is also actively soliciting corporations to evaluate and commercialize these products in their product designs. Various of these companies are supporting the proof of concept projects underway with the DOE and PNNL.
RadMax Compressor
The RadMax positive displacement compressor incorporates the advantages of both positive displacement and centrifugal compressors by utilizing the volumetric energy of a positive-displacement compressor and the kinetic energy of a centrifugal compressor to pressurize a gas. A combination of four distinct sections, this design allows for each section to be configured with a different compression ratio and allows multi-stage compression in one device.
Applications
Compressing refrigerants for industrial, commercial, residential and automotive air conditioning systems; industrial gas compressing; natural gas field and pipeline gas compression; low density gas to high pressure. The RadMax compressor is being tested in DOE SETO and GTO projects that use metal Organic Framework Materials as sorbents fix a thermal compressor and for a dehumidification/carbon dioxide capture system.
RadMax Combined Function Devices:
A attribute of the RadMax technology is the ability to combine approximately one machine function into a single device. The combined function device consists of two cams connected by a common driveshaft in a single housing.
Applications
RadMax external combustion engines, applications with limited space and weight restrictions, such as auxiliary and backup power generation, waste heat recovery, portable pumps, compressors, generators, and compressed gas system throttling energy recovery for A/C and refrigeration systems.
RadMax Pump
A RadMax pump is able to utilize the volumetric displacement energy of the fluid and the kinetic energy of the vane action. A combination of four distinct sections, this design allows for different pumping actions or flow rates/streams in one device.
Applications
The RadMax pump is well suited for fire protection; water and flood control; irrigation; marine; water treatment; oil and gas industry down hole and subsea; industrial processes; heavy industry and construction; and portable pump applications.
RadMax Internal / External Combustion Engines
The RadMax engine is characterized by high torque, compact size, and a high horsepower-to-weight ratio, making it an ideal option for various transportation, and power generation applications. Long service life, low power-to-weight ratio, and increasing environmental concerns and regulations are prompting a second look at the viability of gas turbine engines for more mainstream applications. The company is seeking co-development partners to move further engine development forward.
Applications
Primary and backup power generation; automotive and truck, aviation, marine and industrial applications prime mover, and hybrid vehicles.
Strategy
The company’s guiding business strategy is to develop RadMax technology products for applications that are either looking for a solution, or where its product offers significant advantages in performance and / or financially over incumbent products. This strategy implies that its co-development industry partners would be ‘early adopters’ looking for new ‘green’ products to enhance their market position, broaden their product line, and increase their market share and margins.
