Features

 

The HLA adsorption dryers offer a reduced initial purchase cost, being the OMI cheapest desiccant dryer series still featuring the renowned OMI quality. These dryers can be also optionally equipped with our Energy Management System to further optimize your compressed air costs.  

 

This series of dryers features reliable switching and purging valves designed for high working cycle and long life. Purge valves are also provided with position indicators to facilitate performance check. 

 

The low profile design of the HLA dryers allows for easy access to key maintenance points at operator level, reducing the downtime. Lower silhouette and lifting points simplify handling and also minimize transport costs. The HLAs are equipped with a new digital controller, considerably improving the ease of use.  

 

Optional features: 

  • High efficiency pre-filter and dust filter 

  • Fail-to-shift alarm: it monitors the dryer sequencing functions to ensure proper dryer operation by sensing the pressure in each tower and sending an alarm in case of anomalies. This option is available from models 1000 m3/h and above 

  • IP65 electrical rating plus stainless steel control air tubing (from models 1000 m3/h and above) 

  • Stainless steel control air tubing 

  •  -70° C pressure dew point 

  • Marine painting
