The EC-77N Compressor builds upon the trusted F-50 platform, delivering enhanced performance and advanced features in a familiar footprint. This hybrid compressor automatically switches from water to air cooling in the event of a failure or shutdown in the water-cooled heat exchanger, maintaining a consistent cold head temperature, and then switches back to water cooling for primary operation once the issue is resolved. The EC-77N is a three-phase compressor available in both low and high-voltage versions, operating at 6.5/7.5 kW (50/60 Hz). An updated user interface offers a more intuitive experience, while the redesigned heat exchanger boosts overall performance. The EC-77N pairs with the RDE Series of 4K Gifford-McMahon Cryocoolers.
