Gas chiller LFZ-CHS series

compressed airfor electronicshigh-performance

Product overview
The LFZ-CHS Series gas high-low temperature impact chiller delivers precise, rapid gas ambient temperature control for chips, modules, PCBs and electronic components. It is designed for electrical performance testing, failure analysis and reliability evaluation in R&D and production test environments.

FEATURES

• Temperature range: -120℃～+300℃
• Very fast heating & cooling: examples 150℃→-55℃ in <10 s (model-dependent)
• Maximum gas flow: 30 m3/h (custom option up to 100 m3/h for higher test power)
• Closed‑loop control with real‑time monitoring of the actual IC temperature and automatic adjustment of outlet gas temperature
• Controllable heating and cooling times; supports programmed sequences, manual operation and remote control
• Test example: ambient 20℃, 30 m3/h, 5 Bar using compressed air or nitrogen
