Liquid nitrogen Dewar Möbius™

The ORTEC Möbius Recycler technology provides “tried and tested” liquid nitrogen cooling of your radiation detector in a system where LN2 requires refilling approximately once every other year under normal, continuous operating conditions. This is achieved by the integration of the Sunpower® cryocooler and a specially designed 28 liter liquid nitrogen dewar. The Möbius Recycler provides an excellent strategy for managing counting laboratories which have periodic power failures. A “smart” cooler controller senses when the Möbius is operating on an uninterrupted power supply (UPS) and automatically disables the cryocooler to minimize the power drain. This feature allows extended system operation when using smaller capacity UPS systems. The predictive “time to empty” LN2 level monitor provides status regardless of mains power loss. While your laboratory may be in the dark, you won’t be, when it comes to knowing “time to empty” of the LN2 dewar. Mobius is available in a top load configuration for vertical and horizontal cryostats and with a side-looking or J-type cryostat. Key Benefits Ability to achieve LN2 performance without the requirement for frequent system refilling – thus saving time, money and reducing hazardous material handling. During a loss of input power, the Möbius will continue cooling the radiation detector as if it were a standard dewar. A large 27 liter dewar improves the duration for cooling during a power loss and helps extend the time between system refills.
