• Pressure vessels are designed in accordance with the ASME Boiler and Pressure Vessel Code Section VIII Division 1 • ASME rated pressure relief valves control pressure build-up due to process upset • Expanded metal personnel protection and hot pipe insulation provides added safety measures • NEMA4/4X, IP66 rated controller, polycarbonate enclosure for protection in corrosive environments • Flow models 350 to 450 scfm employ angle seat valves for reliable operation • Flow models 600 to 10000 scfm utilize non-lubricated, high performance butterfly valves • Front panel is equipped with left and...

Putting Waste Heat to Good Use H o w t h e N R G - L E S S e r i e s Wo r k s : 1. ot oil-free air, generated by the air compressor, H is directed into the dryer by a high performance switching valve. 2. he hot air flows downward through the off-line tower, T effectively regenerating the desiccant bed. 3. ot, moist air then travels to the water-cooled heat H exchanger. The cooling water runs counter-flow to the hot air causing water vapor in the air to condense. 4. ondensed liquid is removed in a high performance, C two-stage filter/separator. Bulk liquid and solid particles 3.0 micron and larger...

Understanding Dew Point Performance Th e Ai r C o m p r e s s i o n Pr o c e s s Site conditions are important when understanding dew point The NRG-LES utilizes recoverable heat energy from the air performance of heat of compression air dryers. The NRG-LES compressor to regenerate the off-line bed. flow ratings are based on an ambient air temperature of 85ºF (29ºC) and 60% relative humidity. When compressed to 100 psig (7 bar) and heated to 350ºF (160ºC), the air leaving the compressor will possess a relative humidity of 3%. The dry, hot • igher inlet air temperatures improve regeneration H efficiency,...

Ease of Monitoring The NRG-LES controller is furnished with a comprehensive diagnostic system that provides real-time operating status, service due messages and fault conditions. Information is communicated in a highly visible, two (2) line —sixteen (16) character vacuum florescent text display screen. The controller is equipped with an RS 232 communications port and Modbus registers for remote monitoring S t a t u s Te x t D i s p l a y S c r e e n s • Tower drying (left/right) • Tower regenerating (left/right) • Hours to service (filters/valves/desiccant) • Inlet air temperature (°F/°C) • Outlet...
