Ametek Ortec – Detector Cooling

ICS Integrated Cryocooling System

The ICS integrated electro-mechanical cooling system for HPGe radiation detectors from ORTEC exploits the latest generation in cryogenic technology to provide LN2-free operation with no loss of detector performance. Using a Sunpower industry proven Stirling cooler, ICS is more efficient and reliable than pulse tube designs. Increased efficiency means improved cooling with proportionally less heat generation and lower power consumption. With a cooler Mean-Time-To-Failure (MTTF) of over 200,000 hours.

Mobius Recycler Condensing Liquid Nitrogen Cooling System

The ORTEC Möbius Recycler technology provides “tried and tested” LN 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.

Dewars and Cryostats

Standard liquid nitrogen cooling in a variety of cryostat configurations and dewar sizes to support most radiation detector applications. (For cryostat/dewar specifications, see the configuration guide for your detector type.)
