mb air systems were approached to provide a solution for their old and unreliable Instrument Air System.

Working to the restrictions of the old package base, we provided a comprehensive solution that started within the project design office. Our workshop capabilities allowed a full system mock build and functionality test to give our customer the confidence in our design and equipment.

The Problem

The Gas Terminal’s ageing compressed air equipment came with reliability issues to the critical Instrument Air system. Any new system had to fit within the existing package battery limits and be delivered as soon as possible to relieve the existing equipment.


The Solution

New Ingersoll Rand highly efficient variable speed compressors combined with extensive air treatment to provide ‘oil free’ air and a bespoke piping system with maintenance kept in mind.


The Results

A complete solution designed, mock built, witness tested, and ready to be installed on time. Complete with a custom control philosophy to minimise manual change over achieved by the Ingersoll Rand X8i common controller and interconnecting control.

Key Takeaways

Customised Control Philosophy

A complete control system was provided including:-

  1. Remote Pressure Transducer – Installed in a large air receiver to avoid compressor cycling.
  2. Ingersoll Rand X8i Common Controller – Ensuring automatic compressor load changeover and equal run hours for improved reliability and reduced manual operator tasks.
  3. Interconnecting Control between the state of the art Ingersoll Rand compressor and dryer controllers – Ensuring automatic switch over from Duty to Standby incase of failure.
