Why should filter elements be changed annually?
Filtration provides vital protection against aggressive condensate and contaminants in compressed air that cause corrosion and premature machinery wear
Independent studies show that up to GBP200 per 100 scfm per year can be saved by controlling the purge rates of dryers.
According to domnick hunter massive savings of up to 80% can be achieved with their Multitronic electronic microprocessor controller.
The compact unit is simply retrofitted to desiccant dryers, replacing the existing controller.
The Multitronic constantly varies dryer cycle time to maximise efficiency.
Mark Storey, Product Manager at domnick hunter, says.
"Desiccant dryers have twin chambers of desiccant material.
While one chamber is drying the other is regenerating, after a pre-set time they changeover.
The Multitronic detects any remaining drying capacity and lengthens the cycle time to delay changeover so that the desiccant capacity is fully utilised".
Mark explains: "During the extended cycle period which lasts up to a maximum of 60 minutes rather than the usual 5 minute cycle time, no purge air is consumed for regeneration, which is where the energy savings come from".
The system constantly monitors dewpoint, reacting to changes in air usage or shift pattern to provide air of the right quality at the lowest operating cost possible.
The controller also gives plant engineers flexibility to set dewpoint temperatures at a desired temperature between -25C and -40C enabling systems to be customised, which can be particularly useful for processes that are prone to change due to advances in technology and fluctuations in demand.
domnick hunter offer a 'Dewpoint Dependent' switching option on new dryers, which gives similar savings, the Multitronic however is designed for retrofit, which means companies don't need to replace equipment that is still in good working order to gain savings.
This unit has been available for a number of years now, yet it is still a relatively new and unique concept in compressed air dryer technology as many businesses remain unaware of the level of savings that can be achieved through a comparatively small investment in energy saving technology.
