Micro compressors have applications in medical devices, robotics and “nanosatellites”. The problem of active cooling for photo detectors in “nano-satellites” becomes more important because the majority of space missions target Earth observation, and passive cooling does not provide the required temperatures to achieve the desired SNR levels. Reciprocating compressors used in cryocoolers cause vibrations. VERT Rotors has built an ultralow-vibration rotary compressor with 40mm-long screws, and our prototype delivered 1:10 compression ratio. This “nano” compressor is a non-conventional conical type consisting of an Inner conical screw rotor revolving inside an Outer screw rotor.

This paper presents a method of general geometrical definitions of screw machine rotors and their manufacturing tools. It describes the details of lobe shape specification, and focuses on a new lobe profile, which yields a larger cross-sectional area and shorter sealing lines resulting in higher delivery rates for the same tip speed. A well proven mathematical model was used to determine the optimum profile, compressor housing size, and compressor ports to achieve the superior compressors.

Many oil and gas conferences and events have been put on hold, with some rescheduling far into the future. It seemed only the events that were to take place mid-COVID-19 crisis, as the Global Energy Show was, might be canceled, but later events have pushed their dates back up to more than a year.
The EFRC conference, which was originally scheduled from September 2-3 2020, has been moved to March 9-11 2021.
The Gastech Exhibition & Conference has been rescheduled for September 13-16 2021, from the original dates of September 8-10 2020.
Rio Oil & Gas has been put on hold, with plans to reschedule when suitable dates appear.
Depending on the future situation surrounding COVID-19, many events may also reschedule, though so far original dates still stand. A full view of oil & gas events taking place within the next year can be viewed on our conferences page.
The global market for screw compressors is expected to grow by US$4.2 billion by 2025, claims a report by Report Linker. The growth will be driven by a compounded annual growth rate of 5.4%. Once past the COVID-19 pandemic, growth is predicted to again move back to a new normal.
This report is accessible through the Report Linker website and is available for purchase.
The centrifugal compressor market may experience vast growth in to 2026, according to a study by The Research Insights. The report analyzes the current state of the centrifugal compressor market and predicts the evolution of the market until 2026.

The impacts from the COVID-19 pandemic has caused all DMG Energy Events to be put on hold, including the highly sought after Global Energy Show in Calgary. In its place, DMG events has elected to host live webinars for anyone to view, which can be found on the Global Energy Show website.
The webinars can be viewed live, or for past webinars, on demand. The live shows continue until June 24th.
Upcoming webinars include:
