TECHNOLOGY:

The object of all compressors is to raise the pressure of a gas with the minimum expenditure of energy. There are three principle types of air compressors: Reciprocating compressors: Gas is compressed by positive displacement pistons in cylinders. Flow is controlled by valves Rotary Machines: Gas is compressed by rotors provided with lobes, gears, vanes. Turbomachinery: Gas is driven by high speed impellers rotating in confined case When considering turbomachinery a number of different designations are used: Axial -The Flow is compressed in the direction of the driving shaft.  This is used for the highest flow applications Centrifugal- The Flow is directed radially, and the pressure rise is increased by centrifugal force. Used for high flow rates at moderate pressure. Turboclaw®- A new type of centrifugal compressor, developed by DBS, which can bring the benefits of turbomachinery to low flow applications.

Turbomachinery revolutionised compressor technology by offering a low parts-count and cost, continuous operation, and high efficiency. It soon replaced most positive displacement machines such as piston, screw, and scroll for high flow-rates.

Turbocompressors are however not suitable for low flow-rate applications such as in gas fuel compression, air management systems in fuel cells, or in the final stages of multi-stage industrial compressors. The low flow-rate requires small diameters but operating at ultra-high speeds to achieve high pressures, leading to high cost drives and bearings and low efficiencies.

New patented turbomachine technology from Dynamic Boosting systems overcomes these shortcomings of turbocompressors.

TurboClaw® operates efficiently at relatively low flow rate at moderate pressures.
