What’s inside – The unique technology at the heart of a Vert Compressor

 

Ever wondered what powers a Vert compressor?  We take a look at the innovative technology inside our compressor range to explain how and why it does what it does.

 

With so many traditional types of compressor on the market, one could argue that there has been little in the way of true innovation that goes right to the heart of how air is compressed over the last 40 years.  Many tweaks and incremental changes to traditional compressor technologies such as piston, screw and scroll compression systems have been made but few innovations to the compression approach.

 

This is where the technology at the heart of a Vert compressor is very different.

 

A breath of fresh air

The Vert Conical Rotary Compressor (CRC) technology is truly innovative, it has been designed from scratch and has completely changed the compression approach.  Similar to other screw compressors or pumps, the Vert CRC has two helical elements but places one screw – or rotor – inside the other.  Both rotors spin in the same direction but at different speeds, with the inner rotor acting as a gearing system for the outer rotor.  As the air, gas or other media travels down the conical rotors, the volume continually reduces and so the pressure continually increases until it reaches the discharge end of the compressor.  The clever geometry of the rotors is important as it is responsible for the unique combination of benefits displayed by the Vert Compressor range:

 

  • The interaction of the inner and outer rotors allows the air compression process to run continuously (or in other words the compressors have a 100% duty cycle). This means that the compressor unit does not have to stop during its operating cycle to cool down unlike other compressors on the market which have a 50% or 25% duty cycle.  This is of particular benefit to applications which require a continuous flow of air to the downstream air tools, such as bottling plants or fibre optic cable blowing equipment where a stop start operation can be detrimental to overall productivity.

 

  • Positioning the inner rotor inside the outer rotor minimises any air loss during the compression process. This means that the CRC is able to reach very high pressures for the energy input.   It also means that high pressures can be generated from a small package which means that the compressor is portable and easily moved around a worksite as a source of decentralised air.

 

  • Because the compressor uses rotary motion, it means that exceptionally low vibration levels are generated. This means that any equipment placed on or around a Vert compressor is not going to be adversely affected by high levels of vibration and movement.  This is especially important where the compressor is providing air to applications such as laboratory equipment or CMM measuring machines where stability and accuracy of the equipment is vital.

 

  • As well as low vibration, the CRC unit generates very low noise unlike alternative compressor technologies such as piston. This is particularly advantageous for those working in close proximity to the compressor day to day as it reduces any impact on concentration levels or the risk of long-term hearing damage.

 

  • The smooth interactions between the rotors as they spin also generates pulse free compressed air. This is advantageous for applications such as fibre optic cable installation where a consistent and continuous flow is vital to prevent the travel of the fibre optics in the ducting slowing halfway through the installation process.
