Sales Q&A

 

 

Q: Does the alternating process support simultaneous humidity changes?

A: Can be expanded with a humidity module to achieve temperature-humidity composite alternating testing, with humidity control range of 20% RH to 98% RH.

Q: What is the maximum test load capacity of the device?

A: Standard 100L model has a maximum load of 15 kg, supports customization for larger volumes and loads, with load impact on temperature change rate ≤10%.

Q: How is the energy consumption performance during long-term alternating testing?

A: Utilizes variable frequency compressors and heat recovery technology, saving approximately 35% energy compared to traditional fixed-frequency models, and supports operation during off-peak electricity hours.
