What cooling capacity do your models offer?

Our models cover a wide range:

HL-ST80W series – ≥24W at -80°C (ambient 30°C±2°C)

HL-ST200W series – ≥38W at -100°C (hot end 42°C±2°C)

HL-ST1200W – >245W at -100°C (ambient 23°C±2°C)

You can choose based on your required temperature and cooling load.

How fast can the cooler reach the target temperature?

Cool-down time depends on the model and load:

ST80W – ≤5 min (to -80°C with 6400J load)

ST200W – ≤30 min (to -100°C with 39400J load)

ST1200W – <20 min (to -110°C with 76600J load)

How energy-efficient are Hualeng's Stirling-based freezers compared to traditional compressor-based models?

Our Stirling cryocoolers are significantly more energy-efficient. Thanks to the highly efficient linear motor drive and the thermodynamic cycle of the Stirling technology, our freezers typically consume up to 30% less energy than traditional compressor-based refrigeration systems performing the same task. This translates to lower operational costs and longer battery life for portable operations.
