The E-77A Compressor builds upon the trusted F-50 platform, delivering enhanced performance and advanced features in a familiar footprint. This water-cooled, three-phase compressor is available in both low and high-voltage versions, operating at 6.5/7.5 kW (50/60 Hz). Equipped with inverter technology in both the cold head and the compressor, the E-77A ensures faster cooldown times, improved energy efficiency, and universal 60 Hz operation. An updated user interface offers a more intuitive experience, while the redesigned heat exchanger boosts overall performance. The E-77A pairs with the RDE Series 4K Gifford McMahon Cryocoolers and is an integral part of our RJT-100 4K GM-JT Cryocooler system.
