Air Compressor

New Air Compressor generates over 50% efficiency savings and cuts Carbon Footprint by up to 2 tonnes per year.

After several years of dutiful service the time came to retire our trusted air compressor.  We obtained the EcoAir 10 from Compressed Air Management, our local, expert supplier, over 10 years ago and has been in constant daily service ever since.  However, as with all areas of the business, technology moves on and we were aware that a newer, more energy efficient model would further emphasise our continued commitment to achieving Year on Year CO2 savings.

We contacted Compressed Air Management who recommended an Ingersoll Rand system with Variable Speed Drive (VSD).  The benefits are 2-fold.  Motors on traditional compressors run at full speed all the time they are on, and use a series of valves to match their output with demand.  VSD technology is much more like a petrol engine, in that it starts slowly and matches its speed with demand.  This results in large efficiency savings over regular compressors.

So, having placed our order in June, we began a 5-day period of hourly data-logging of the old system using ECO-EYE Elite 100 energy monitors, giving us accurate performance data that we could convert into carbon emissions and cost savings.  Once the new system was installed the data logger was fitted and the system was monitored for the same period of time.

Not only is the new compressor quieter but we found that on average it was over 50% more efficient than the old system. Over the course of 12 months we have calculated that this will transfer into a carbon saving of approximately 2 tonnes, and during the expected lifespan of the unit the cost savings will roughly equal the cost of the unit.

Managing Director, Chris Benson said, “We’re really impressed with the performance of this compressor even though initially its close resemblance to a wartime atom bomb was a little disconcerting! It certainly ticks all the efficiency and environmental boxes.”
