The Haier DW-40L959BP is a 959 L (33.9 cu ft) upright -40 °C biomedical freezer with a universal 100–230 V, 50/60 Hz input — a large-capacity mid/low-temperature freezer for samples, plasma, and materials that need a true -40 °C environment, colder than a -30 °C unit but not the -80 °C of a ULT. A high-efficiency hydrocarbon (HC) refrigeration system holds the -20 °C to -40 °C range at just 42 dB(A), and an LED microprocessor controller runs temperature and a full alarm suite. Its 33.9 cu ft cabinet accepts adjustable wire shelves or optional plastic blood-bag drawers, making it flexible between general and blood-product storage.

Application Profile
The DW-40L959BP serves large-volume -40 °C storage — the band required for certain plasma products, tissue, reagents, and long-term sample banking that exceeds -30 °C capability but does not need ultra-low temperatures. At 33.9 cu ft it holds a substantial inventory in a single cabinet, and its interior converts between two wide adjustable wire shelves and up to 42 optional plastic blood-bag drawers, so it adapts to either boxed-sample or plasma-unit workflows. The universal 100–230 V input accommodates a range of facility services. (See ult-freezer-selection.)
Three inner doors limit cold-air loss during access, the low-power hydrocarbon system runs quietly at 42 dB(A), and standard RS485 output (with optional USB) supports temperature logging and integration into monitoring systems. Alarms cover high/low temperature, power failure, low battery, high-ambient, sensor error, and door-ajar.
Frequently Asked Questions
What temperature range does the Haier DW-40L959BP hold? -20 °C to -40 °C, from a high-efficiency hydrocarbon refrigeration system with manual defrost.
What is its capacity? 959 L / 33.9 cu ft — a large-format -40 °C cabinet. (Note: the price-list description lists "818 L / 33.8 cf," which corresponds to the smaller DW-40L818BP; the DW-40L959BP is 959 L / 33.9 cf per the Haier datasheet.)
Can it store blood products? Yes — the -40 °C range plus optional plastic blood-bag drawers (21 or 42) make it suitable for plasma and similar products; two wide wire shelves serve general storage.
What power does it require? A universal 100–230 V, 50/60 Hz input, drawing up to 800 W, at 42 dB(A).
Does it support temperature logging? Yes — RS485 output is standard and a USB interface is optional for temperature records and monitoring integration.
Ordering & Configuration
quote-based. The DW-40L959BP is a capital biomedical freezer sold through a quote. At quote we confirm the input voltage and receptacle, floor space for the 1296 × 998 × 1980 mm cabinet, the shelf-versus-blood-bag-drawer configuration, monitoring/data accessories, and installation. Warranty and any certification details are confirmed with the quote, and lead time is provided at quotation. Request a quote to configure the DW-40L959BP for your -40 °C storage.
Choosing the -40 °C band: the DW-40L959BP is the large 33.9 cu ft option when samples need -40 °C. Choose the DW-30L698 for -30 °C plasma storage, the compact DW-25L92 for small -25 °C needs, or the DW-86L ULT line for -86 °C archival storage.
