The situation: a client’s production facility was being limited by the installation of two desiccant air dryers that were unable to accommodate the volume of compressed air required to meet a desired increase in production, unless both were run in parallel. This left the site with no standby capability should either of them fail and two dryers working on the very edge of their limits. Clearly not sustainable.
The solution: our proposal saw the replacement of the existing air dryers with two Parker VWM 520 zero purge vacuum regenerated dryers, each with the capacity to accommodate the output of the four air compressors, that together were producing 2516 cfm. This ensured not only the return of a full duty / standby capability for the site but also the ability for duty rotation.
The outcome: the increase in available productive air has led to greater efficiencies, while running costs have decreased significantly. The client has seen annual savings of £47,400 and with the UK government carbon emissions figures showing 0.233 kg of CO2 per kWh of electricity, 8000hr per annum operation has resulted in a carbon reduction for the site of 205 tonnes.
