The Haier HBX-IIA is a liquid-nitrogen (LN₂) backup system for Haier Biomedical -86°C ultra-low temperature freezers. It injects LN₂ into the cabinet to hold storage temperature during a power outage or compressor failure — the difference between a serviceable event and the catastrophic loss of an irreplaceable sample archive. It runs on standard 115V/60Hz control power and is the recommended safeguard for biorepositories and high-value ULT storage.
| Spec | Value |
| Type | LN₂ (liquid nitrogen) backup / injection system |
| Function | Maintains freezer temperature during power or compressor failure |
| Compatible equipment | Haier -86°C ULT freezers (DW-86L series with LN₂ backup option) |
| Control power | 115V/60Hz |
| List price | $2,500.00 |
| LLS price | $2,125.00 |
Order the HBX-IIA when the contents of a -86°C freezer are worth more than the freezer itself and any warming event is unacceptable — master cell banks, long-accrued biobanks, clinical-trial specimens. It is designed to integrate with Haier DW-86L ULT freezers that carry the LN₂ backup option, activating automatically when cabinet temperature rises toward the alarm threshold and injecting liquid nitrogen to sustain storage temperature until primary cooling or power is restored.
Because LN₂ backup requires a facility liquid-nitrogen supply and the correct cabinet provisioning, confirm your specific freezer model's compatibility and the LN₂ connection/consumption requirements with a Legacy Lab specialist before ordering. (Haier also offers a CO₂ backup option where LN₂ is not available.)
The HBX-IIA is quoted alongside its host freezer. Add it to a quote and a Legacy Lab Supplies specialist will confirm freezer compatibility, LN₂ supply requirements and installation before order. Lead time is quoted per configuration; contact us for current availability.
Add the HBX-IIA LN₂ backup to any Haier -86°C freezer where sample survival must not depend on a single compressor or the building's power. Where liquid nitrogen is not on hand, ask about the CO₂ backup alternative.
