Independently developed by KOMEG, the KFH-1000SF4W0 ultra-low temperature test chamber breaks the -70℃ technical barrier of traditional industrial-grade environmental test equipment. It can accurately simulate extreme low-temperature environments, providing reliable experimental conditions for research on the extreme environmental behavior of materials and performance verification of high-end products.

Core Temperature Performance

Minimum Temperature: -90℃ (lower than the WMO-certified natural minimum temperature in Antarctica of -89.2℃)

Temperature Fluctuation: ≤±0.5℃ under no-load conditions

Full Temperature Range Control: Precise temperature control from -90℃ to +180℃

Cooling Rate: ≥4.0℃/min (from 20℃ to -70℃)

Temperature Uniformity: ≤2.0℃ at -90℃

Continuous Operation Stability: 720h drift ≤±0.3℃

Certification: CNAS-certified, with test data directly applicable to scientific research reports and product certification

Key Technical Configurations

Refrigeration Technology: Adopts an innovative auto-cascade refrigeration topology combined with refrigerant flow state matrix control technology, reducing the steady-state operating power at -90℃ by 33% compared with equivalent products.

Sealing & Insulation: Equipped with a polytetrafluoroethylene-ceramic fiber composite sealing system and a vacuum insulation panel (VIP) + nano-aerogel composite insulation structure to ensure sealing and thermal insulation under extreme low temperatures.

Control Function: Supports power failure recovery and multi-mode precision control, adaptable to complex temperature change curve tests.

Application Fields

Widely used in three high-end fields: verification of extreme environments for aerospace materials, research on safety boundaries of new energy batteries, and deep-cold storage of biological samples.
