Export Control Policy
When applying a refrigerator to a cryocooler for optical
sensors, the cryocooler falls under row 6.A.2.d.2 of the control
list established by The Wassenaar Arrangement, which is
equal to row 10(2) of appended table 1 of Japan's Export
Trade Control Order.
Customers must follow all related rules and regulations such
as Foreign Exchange and Foreign Trade Act and take
appropriate procedures when exporting or re-exporting our
refrigerators.

Page 7: Safety Instructions
The volume of nitrogen gas is 700 times of liquid nitrogen. Sealing liquid nitrogen in an airtight space produces high-pressure gas of 700 atm and may result in explosion. Use liquid nitrogen in the condition constantly open to the air. ULVAC CRYOGENICS INCORPORATED... - Page 8 High-pressure helium gas is filled in this unit. When disassembling or disposing of the unit or parts, be sure to discharge helium (no need to discharge helium for regular maintenance). In addition, never attempt to install the apparatus under the atmosphere of hydrochloric acid-based, chlorine gas-based, and other corrosive gases. ULVAC CRYOGENICS INCORPORATED...
