Reduce costs by suppressing helium evaporation! Eliminate supply concerns!
■Product Introduction The helium re-condensation device eliminates boil-off by re-condensing evaporated liquid helium within the device using a refrigerator, thus making the replenishment of liquid helium unnecessary. It contributes to the 'management reduction' and 'running cost reduction' of liquid helium, which is essential for the operation of the device. Additionally, by connecting the device in a 1-to-1 manner, it serves as an effective measure to prevent contamination within the device during the reuse of liquid helium gas. Due to the characteristics of ultra-low temperature equipment, customer requirements can vary widely, necessitating tailored designs for product details that meet specific needs. Therefore, our company is able to provide speedy responses and proposals by consistently handling everything from development to design and manufacturing of the device.

basic information
■ Low vibration type using pulse tube refrigerator ■ Capable of long-term operation and liquid level maintenance ■ Equipped with vibration isolation mechanism to reduce measurement impact ■ Compatible with various companies up to NMR 600MHz ■ Recommended product by Burker Japan The selection of the model for our helium recondensation device can be made by checking the natural evaporation rate of liquid helium (L/day) in the equipment you own. The natural evaporation rate of liquid helium that can be recondensed with this device is from 1L/day to 18L/day. * Long-term operation and liquid level maintenance are being conducted at our Tsukuba Research Institute.

Applications/Examples of results
We have a proven track record of delivering helium recondensation systems to numerous research institutions and universities nationwide. In experiments conducted by a certain customer using a liquid helium dewar for ultra-low temperatures, they managed the liquid level by transferring liquid helium each time they conducted an experiment. When the liquid level reached the lower limit, it was necessary to transfer again, leading to additional operational costs outside of the actual experiments, which became a challenge. Therefore, we introduced our helium recondensation system. Since it can be installed on existing liquid helium dewars, they were able to use the same experimental equipment as before. Furthermore, with 24-hour unmanned operation, it continuously maintains the helium liquid level, allowing them to focus on their experiments.
