Engineering Progress Update for RadMax Technologies

SPOKANE, WASHINGTON--(Marketwired - Dec. 5, 2016) - (OTC PINK:RGUS): REGI U.S., Inc.'s engineering team and management are pleased to provide the following updates on the Company's RadMax Technology:

Engineering Progress Update for RadMax Technologies

RadMax Technologies now has seven engineers at work testing the diesel engine and designing new applications based on RadMax™ rotary technology.

Phase 1 testing of the diesel engine which measured the performance of the engine in a static state has been completed. This included static compression tests of the oil, apex, and side seals, as well as dry friction test. Paul Porter, Chief Engineer, stated that the results of these tests met or exceeded expectations.

Phase 2 testing of the diesel engine is on-going and involves measuring the performance of sealing and mechanical component systems while operating in a dynamic state. This includes testing of chamber sealing and lube oil systems, which is followed by spin testing of the engine assembly consisting of actuation assembly and operation, engine balancing, compression, temperature, vibration, noise signature and wear analysis.

In addition to testing the diesel engine our engineers are aggressively pursuing new applications that address current market demand for more efficient and compact devices. At present these efforts are being worked on concurrently by four teams with the following objectives: a) design of a 40 HP gas/natural gas rotary engine, b) design of a compressor for refrigeration applications, c) design of a gas expander for refrigeration applications, and d) exploratory work on utilizing the RadMax™ technology for applications in the oil and gas industry.

We believe that successful proof of concept on any of these projects will facilitate joint co-operation and development with industry partners.

ABOUT REGI U.S., INC.

RadMax Technologies, Inc. the wholly owned subsidiary of REGI U.S., Inc. is developing for commercialization an improved axial vane type rotary engine known as the RadMax™ rotary technology used in the revolutionary design of lightweight and high efficiency engines, compressors and pumps. The RadMax™ engine has only two unique moving parts, the vanes (up to 12) and the rotor, compared to the 40 moving parts in a simple four-cylinder piston engine. This innovative design makes it possible to produce up to 24 continuous power impulses per one rotation that is vibration-free and extremely quiet. The RadMax™ engine also has several capabilities allowing it to operate on fuels including gasoline, natural gas, hydrogen, propane and diesel. For more information, please visit radmaxtech.com
