Adsorption compressed air dryer Ultradryer HRS+

externally heated

The Ultradryer HRS+ model of heat regenerated adsorption dryers is the most energy efficient option, providing low operating costs as well as easy maintenance. With Ultradryer HRS+ dryers, the desorption and cooling process is accomplished with ambient air drawn in by a blower. Compressed air is not used during the desorption or the cooling phase. Since the desorption occurs in counter current flow, only low energy consumption is required. The Ultradryer HRS+ is therefore the most energy efficient option. Process Characteristics Desorption in counter-current flow to the adsorption direction with externally heated ambient air Cooling with ambient air (up to size 2750 with partial-vacuum cooling) Designed for automatic and continuous operation Features Energy-saving (Zero Purge, low desorption temperature) Ultraconomy dewpoint control for more energy efficiency Dry gas / purge cooling on demand for reliable and stable dew point performance High temperature resistant painting for long-life corrosion protection and high temperature resistance Valve position control supporting reliable and safe operation Alarm contacts and ethernet communication Interface for enhanced monitoring of system performance Easy maintenance
