RadMax® Technology

Up to 12 vanes slide axially through the rotating rotor as they follow machined cams in the ends of the stationary stator housing. Chambers form at both sides of the rotor between the rotor, stator walls and vanes. The chamber volume changes as the vane follows along the cam profile during rotor rotation creating up to 24 compression or expansion events per revolution. This results in up to 48 compression, expansion, pumping, or any combination of such events per rotation. Desired device configuration is accomplished through the flexible placement of simple intake and exhaust ports in the cam.

RadMax Rotary Cycle


RadMax® Technology

By simply changing the cam profile and/or intake and exhaust porting locations, a RadMax device can be designed as an internal combustion engine, compressor,

pump, gas expander, or a combination of the functions.

RadMax Internal

Combustion Engine Cycle

RadMax Internal Combustion Engine Can be configured as compression ignition (diesel) or spark ignition using gasoline, natural gas, etc. fuels.

Key Advantages: • Compact size & weight (~ 25% of comparable hp

piston)

• High power to weight ratio (>1 hp/lb)

• High internal expansion ratios possible (20:1)

• Continual, smooth rotary motion

• Easily scalable 20 – 1,500hp

• Low part count and fewer moving parts; conducive to rapid change-out replacement, reduced maintenance costs and increased reliability

Applications: Primary and backup power generation; automotive & truck, aviation, marine and industrial applications prime mover; hybrid vehicles


A larger expansion than compression volume is possible in a

RadMax® internal combustion engine which can result in increased

engine efficiency of 10 – 15% over comparable hp piston engines!

RadMax engines are able

to accommodate a

greater expansion volume

(Ve) than compression

volume (Vc). This results

in more work being

extracted from the

expanding gases and

increased engine

efficiency and fuel

economy.

IC Engine Extended Expansion Cycle



RadMax Prototype Bus A/C Compressor

RadMax Compressor A 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. This results in an exceptionally energy efficient device.

Key Advantages:

• Able to efficiently compress low density gases and can better handle entrained liquids in gas

• High internal compression ratios possible (20:1)

• High volume output to size ratio

• Scalable from small to very large devices

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



In principle, gas expansion is compression running in reverse. Unlike turboexpanders, a positive displacement RadMax gas expander is able to capture and convert both kinetic and pressure-volume energy in gas expansion applications.

RadMax Gas Expander

• Able to efficiently expand low density gases and can better handle gas entrained liquids

• High internal and potential automatic variable expansion ratios possible (20:1)

• Higher work efficiency at lower speed

• Scalable from small to very large devices

Applications: Prime mover (standalone & in turbine engine); natural gas throttling energy recovery (pipeline

distribution & compressing stations); air conditioning systems throttling energy recovery; waste energy recovery; power generation

Key Advantages:

RadMax Prototype Gas Expander


RadMax Prototype Water Pump

The RadMax positive displacement pump pairs the high volume capacity of positive displacement pump with the simplicity and efficiency of a centrifugal pump. A RadMax pump is able to utilize the volumetric displacement energy of the fluid and the kinetic energy of the vane action. This results in an extraordinarily energy efficient pump.

RadMax Pump

• Multiple smooth pumping actions per rotation creates high output volume to size and weight ratios

• Better handling of gas-entrained liquids

• Self priming & auto re-priming

• Can operate as a boost or lift pump

A RadMax technology device is comprised of two cams connected by a common driveshaft in a single housing. By using separate vane actuator systems, each cam can have a different compression or expansion ratio making it possible to have two separately functioning cam cycles (i.e. engine, pump, compressor, or gas expander) in the same device.

NG Distribution System Throttling Energy Recovery


• As well productivity declines reciprocating compressors lose sufficient suction and stall. Gas must be

recirculated at each compression stage to maintain minimum required suction to the compressor to insure

proper operation. Solution is to recycle gas; very inefficient and expensive in terms of loss revenue.

• Typical pressure reduction valves used in the recirculation circuits can not capture stored energy in the

high pressure gas stream.

• RadMax gas expander and generator can potentially capture 20% of lost energy and convert to electricity.

• Expanded gas can also be used to augment inter-stage cooling.
