Vert’s mission is to accelerate innovation in the world’s industries, by making 2-3x more power available from compressed air, and by making work safer and more comfortable. The key to acheiving this goal is very compact, highly powerful and low-noise air compressors.
Timeline of Vert Rotors:
At our Compressor Design Centre and Ultra-precision Factory in Edinburgh, we develop, test and manufacture compressors that produce 200% higher pressure in a single stage than what people though was possible, and solve the problem of noise and vibration.
Vert manufactures to highest accurcy of CNC milling precision, at geometrical tolerances of up to +/-5 microns. Such ultra-precision is achieved with 5-axis CNC milling machines with linear drives and thermal compensation, and high-end CAM software. But the true secret is the expertise and passion of our team.
What is conical screw compressor? It is an evolution of the conventional screw compressor (we call it “screw compressor 2.0”). Vert Rotors developed this new design in 2013. It consists of the Male (Inner) screw revolving inside the Female (Outer) screw. It is different to the traditional twin-screw, where the Male screw and the Female screw are sitting side-by-side in the housing.
Conical compressor does not have clearance between the Male, the Female screws and the Housing, because the Female screw acts like a Housing. This means that the leakage path for the gas is much reduced and even a small (sub-1kW) conical compressor remains highly efficient.
What is so special about it? The conical compressor is highly compact (because one screw sits inside the other), very powerful and efficient. It produces 2-3 times higher pressure in a single stage, at low niose and vibration, than its rivals. A small 0.8kW conical screw is 50% more efficient at 8 barg than an alternative low-vibration scroll compressors of the same capacity.
How small/big is this new compressor? The conical screw compressor can be very small or very large. So far, Vert Rotors built and tested a range of sizes, from a tiny 20W screw compressor, which fitst the palm of a hand, to a large 10kW machine for 75 m3/h. This is a big difference with traditional twin-screw compressors, which cannot be smaller than 2.2kW. Even the smallest conical screw compressors successfully produce high pressure of 16-22 bar in a single stage.
Why does it matter, and how does it compare to the current level of technology? Today, screw compressors occupy 60% of the global market. The conventional twin-screw compressor was invented and first patented in 1934, and by now they have occupied the biggest share of the market. For over 80 years, the core design of the screw compressor did not change. The conical screw compressor was first patented in 2014 by Vert Rotors. By today, Vert has demonstrated that the conical screw compressor is more efficienct in the industrial size, and in the portable sub-1 kW size. We think the conical design is only at the start of its journey. In the coming years, it is most likely to improve its efficiency even further.
What does Vert Rotors do? Vert has developed a full suite of manufactuing methods to produce this new and wonderful machine. We fully manufacture conical compressors and package them into finished compressor units in-house in Edinburgh, and keep the expersite and know-how. We supply conical screw compressors to customers all over the World. Please see our Products for more details.
Air compressors are devices that store pneumatic energy for future use. They drive an infinite variety of industrial and domestic applicaitons. At Vert Rotors, we design and develop a new compressor technology, which is more efficient, and achieves 2-3 times higher pressure, or in other words stores 2-3 times more energy in the same volume. Our technology will fundamentally change the industry.
We are challengers and innovators, and we do not take “no” for an answer. Our key values are: honesty and integrity, hands-on engineering, passion for precision.
Vert’s base is in the capital of Scotland. Over the course of time, Edinburgh was home to many world’s innovations: electromagnetism by James Clark Maxwell, telephone by Alexander Graham Bell, Higgs Boson by Peter Higgs, to name just a few. Edinburgh is not only a landmark of sciende and engineering, it is a great place to live: in 2015, uSwitch ranked Edinburgh 1st in the top 10 places to live in the UK in their study of 138 UK regions. In 2017, Edinburgh was named 2nd in the World for quality of life.
