Comparison of core differences
1. Different functional positioning
Low temperature cold traps are mainly used for material separation and capture, while low-temperature recirculating chiller focus on temperature control and heat transfer.
2. Differences in working methods
Cold trap is a passive operation that relies on natural condensation on low-temperature surfaces; The circulation chiller works actively by pumping coolant to achieve heat exchange.
3. Temperature range
Cold traps typically achieve lower temperatures (especially when using liquid nitrogen), while circulation chiller have a relatively narrow temperature range but higher control accuracy.
4. System complexity
The cold trap structure is relatively simple, while the circulation chiller includes multiple complex components such as a compressor, pump, and control system.
