Hydrocarbon-Refrigerant Ultra-Low Freezer with Low Global Warming Potential

低全球变暖潜能值碳氢制冷剂超低温冷冻箱

Institutions preparing for HFC restrictions can move to natural refrigerants with this ultra-low freezer. R290 handles the high stage and R170 or an ethane-propane blend the low stage, giving a GWP below 5. Charge stays within IEC 60335-2-89 limits. Capacity is 300-700 L at -50 to -86 °C, with empty pull-down in 6-9 h.

Temperature range: -50 to -86 °C
Net capacity: 300-700 L
High-stage refrigerant: R290 (propane)
Low-stage refrigerant: R170 (ethane) or ethane-propane blend
Global warming potential: Below 5
