Key Highlights
- Provides extended operation with minimal LN₂ refilling — typically requires filling only once every ~2 years under continuous use.
- Smart controller reduces UPS power drain and supports cooling during power loss.
- Large 25 L dewar and LN₂ level monitor for proactive system management.
- Remote diagnostics and Windows PC interface.
- Compatible with different cryostat configurations (vertical, horizontal, J-style).
Description
The Möbius Recycler is a cryogenic cooling system for HPGe radiation detectors that uses liquid nitrogen condensation to maintain detector temperature with minimal refill requirements. By combining a cryocooler with a specialized 25 L LN₂ dewar, the Möbius system delivers reliable cooling performance with reduced hazardous handling and long standby times, even through power outages.
