Shi Sumitomo RDK-415D Head Cryocooler - Pioneering Performance in Cryogenic Cooling

The Shi Sumitomo RDK-415D Head Cryocooler is a testament to technological advancement in the realm of cryogenic cooling. This state-of-the-art device, developed by the renowned Japanese manufacturer Shi Sumitomo, is designed to deliver superior performance in low-temperature applications.

The RDK-415D is a Joule-Thomson (J-T) type cryocooler, known for its efficiency and versatility. It operates on the principle of expansion cooling, making it an ideal choice for cooling a variety of instruments and systems that require temperatures as low as 77 K (liquid nitrogen range).

The cryocooler features a robust, compact design, with a weight of approximately 34 kg (including the refrigerator and the cold head). The dimensions of the cold head are 157 mm (height) x 173 mm (width) x 373 mm (length), making it suitable for integration into a wide range of systems.

The RDK-415D boasts a cooling capacity of 0.5 W at 77 K and 0.2 W at 40 K, ensuring efficient cooling of your system. It is equipped with a built-in thermal radiator and a refrigerator, which work together to dissipate heat and maintain the desired low temperatures.

The cryocooler also comes with a user-friendly control system, allowing for easy operation and monitoring of the cooling system. It is designed to operate at voltages ranging from 100 V to 240 V AC, making it compatible with a wide range of power sources.

In summary, the Shi Sumitomo RDK-415D Head Cryocooler is a powerful, reliable, and versatile solution for low-temperature cooling applications. Its compact design, efficient performance, and user-friendly control system make it a popular choice among researchers, technicians, and engineers working in the fields of physics, astronomy, and materials science.

The Shi Sumitomo RDK-415D Head Cryocooler is a high-performance cryocooler designed for various applications, such as infrared imaging and spectroscopy. Here are some pros and cons to consider before making a purchase:

1. High cooling capacity: The RDK-415D offers a cooling capacity of 6 Watt at 77 K, making it suitable for applications requiring a high level of cooling.

2. Compact design: Despite its high performance, the RDK-415D has a compact design, which makes it easier to integrate into various systems.

3. Low vibration: The RDK-415D produces low vibration levels, which is beneficial for applications that require stability, such as infrared imaging.

4. Long lifetime: The RDK-415D is designed for a long lifetime, with a mean time between failures (MTBF) of 30,000 hours.

1. High cost: The RDK-415D is a high-performance cryocooler and its cost reflects its capabilities.

2. Complex operation: The RDK-415D requires careful calibration and maintenance to ensure optimal performance.

3. Limited availability: The RDK-415D may not be widely available in all regions, which could make it difficult to obtain spare parts or technical support.

In conclusion, the Shi Sumitomo RDK-415D Head Cryocooler is a high-performance cryocooler with a compact design, low vibration levels, and a long lifetime. However, it is a high-cost option, and its operation requires careful calibration and maintenance. If the high cooling capacity and compact design meet your application requirements, and you are willing to invest in the necessary maintenance, then the RDK-415D could be a good choice. If the cost is a concern or if you are looking for a more user-friendly option, you may want to consider other cryocoolers available on the market.
