Frequently Asked Questions
How fast is 'rapid' freezing? Can it compete with liquid nitrogen?
The blast freezer reaches -40°C in <30 minutes—not as fast as liquid nitrogen immersion (~5 min) but sufficient for most biobanking, pharmaceutical, and food applications. Advantage: no hazardous cryogenic handling, no boil-off loss, simpler maintenance. Liquid nitrogen is reserved for ultra-long-term (>20 year) archival.
What's the holdover time during a power failure?
With heavy insulation and sealed door, the -40°C temperature can be maintained for 8+ hours during power loss. For critical samples, integrate with a backup generator for extended outages.
Can I store vaccines and biologics long-term in this freezer?
Yes, subject to vaccine-specific stability data. Indeecon freezers hold ±1°C stability at -40°C, meeting WHO and ICH requirements for vaccine potency preservation. Consult your vaccine manufacturer's storage specifications—some may require -70°C ultra-low freezers for decade-long storage.
Is the blast cooling mode more expensive to operate?
Blast mode uses slightly more compressor power (~15% higher consumption during cool-down). Once stabilized at -40°C, energy consumption is equivalent to standard operation. Cost delta is ~$5–10/month for typical laboratory usage.
What's the typical defrost cycle?
Auto-defrost cycles every 12 hours for 20 minutes during low-demand periods (e.g., nights/weekends). Manual defrost is also available. Drain plug at the base collects meltwater—route to sink or container to prevent pooling.
