SHI Cryogenics Group Releases Highest Capacity 4K Cryocooler to Date
New RDE-418D4 Cryocooler Increases Cooling Performance by 20% Compared to Existing Models
By: SHI Cryogenics Group
Compared to SHI's RDK-415D 1.5W 4K Cryocooler, the RDE-418D4 features an optimized design that increases cooling performance by 20% without increasing the cryocooler's physical size or the compressor's input power. The new cryocooler has a first stage capacity of 42/50W at 50K (50/60Hz), and a second stage capacity of 1.8/2.0W at 4.2K (50/60Hz). The RDE-418D4 also features the same interface design as the RDK-415D, easing the ability to swap the new cryocooler into existing cryostat designs.
In addition to the cryocooler, the complete system includes a helium compressor, gas lines and power cables. It is CE and UL certified, with a suggested maintenance interval of 10,000 hours. The F-50 compressor is a three-phase, indoor, water-cooled unit that is available in both high and low voltage models. All Freedom® series compressors utilize highly-reliable scroll compressor capsules, have an industry-leading 30,000 hour maintenance interval, and are designed exclusively to deliver high pressure, oil-free helium to cryogenic refrigerators.
Like all SHI cryocoolers, the RDE-418D4 is competitively priced, and provides a stable low-temperature solution for a variety of research purposes, including helium liquefaction, superconducting magnets and detector cooling. The SHI Cryogenics Group has the largest installed base of cryocoolers around the world, and supports its customers with a global service and support network of twelve offices and numerous representatives.
