eCool® Technology: A Cool Innovation
Compressors generate heat. FS-Curtis' exclusive eCOOL® technology provides protection from heat and reduces thermal stress, ensuring maximum reliability and component longevity.
By combining smart compressor layout with intelligent component selection, eCOOL technology maximizes cooling airflow for greater energy efficiency, improved reliability, and increases service life up to 50% longer for motors and electrical components and up to 30-50% longer for bearings, hoses, and seals.
The ultimate in system protection and reliability:
- Protects critical components from compressor-generated heat
- Extends component life and reduces downtime
- Compartmentalized airflow design and standard aftercooler optimize thermal management
- Air-cooled oil cooler and aftercooler ensure efficient heat dissipation
