Non-standard voltage 230/1/60 NPT connections No-loss intelligent drain New Energy Saving dryers series. Thanks to the innovative and patented three-circuit heat exchanger (refrigerant, glycol and compressed air), the new ESD dryers save energy effectively from 0 to 100% load allowing a reduction in operating costs guaranteed up to a maximum of 90%. Particularly suitable for all applications that require a partial load or intermittent use of compressed air. The dryer is equipped with an additional feature of the display that allows to view and verify the current and historical savings. The new electronic control board also includes a second probe dedicated to the glycol control to ensure maximum efficiency avoiding freezing problems. The variable speed fan control allows to achieve maximum performance in all conditions of load and ambient.
