JT Refrigerator
JT Closed Cycle Refrigeration systems are custom designed to meet the requirements of the customer. This cooling system provides continuous cooling within the temperature range of 70K to 293K. Because there are no moving parts in the cold head, this system has very low vibrations.

The JT refrigerator system consists of a cold head, compressor, and two gas transfer lines. The compressor is designed for maintenance-free service with a mean time between failures of 100,000 hours.

Features

• Operating temperature range 70K to 293K
• Closed cycle operation
• Indefinite hold time does not require LN₂ or LHe
• Low vibration cold head
• Designed to customer specifications
