Reduce your system's carbon footprint
May 19th 2008 An energy management system developed by domnick hunter has been designed to save significant amounts of power consumed during the drying of compressed air.
For a limited period, only in the UK, domnick hunter is fitting its Dewpoint Dependent Switching (DDS) energy management system free of charge on all new orders for Pneudri MidiPlus MX heatless and MAXI heat regenerative desiccant dryers.
A dryer’s power requirement is usually optimised for the maximum design conditions of the dryer, i.e 100% of rated flow, minimum pressure and maximum temperature. Inclusion of the DDS energy management system ensures the power consumed is directly proportional to the amount of water vapour entering the dryer.
For example, in a compressed air system with a compressor of 160 kW output and a Pneudri MX heatless dryer installed, typically averaging 70% of rated flow, DDS could save the user 153,000 kW of energy every year. This equates to an annual environmental saving of 66,000 kg of CO2.
Every Pneudri dryer is protected with energy efficient oil-x evolution pre- and after filtration which, when compared to ordinary filtration, can increase the energy savings by a further 58,000 kW. In total, this equates to an energy saving of 211,000 kW and an environmental saving of 91,000 kg of CO2 per annum.
Obviously, if the rated flow of the dryer was decreased further during operation, then even further energy savings would be made.
All domnick hunter filtration and purification products are designed with the philosophy of air quality, energy efficiency and low lifetime costs. More articles from Parker Hannifin Ltd (Domnick Hunter Division): |
