The Haier HBX-IIB is a CO₂ back-up system for Haier Biomedical ultra-low freezers, adding an automatic layer of sample protection when a power outage or compressor fault threatens the cold chain. On 115V/60Hz, it injects CO₂ into the freezer chamber to hold a safe low temperature until power or refrigeration is restored.

Compatibility & When to Order This SKU
Order the HBX-IIB alongside a Haier ULT freezer (the DW-86L JA, BPT, and BPST families list an optional CO₂ backup) whenever stored samples are too valuable to risk during an extended power loss and a dual-refrigeration or generator backup isn't already in place. It is the reactive safety net: on a temperature excursion the system releases CO₂ to keep the chamber cold. Confirm the target freezer's backup provision and CO₂ supply requirements when ordering, and plan for a CO₂ cylinder and regulator on site.
