4 °C solar direct‑drive blood bank refrigerator designed for storage of whole blood, medicines, biological products and other laboratory items that require approximately 4 °C storage, especially in health‑care units with unstable or absent mains‑power supply. The unit operates exclusively via direct solar power input, without an intermediate battery, making it suitable for remote areas, mobile blood‑donation posts and rural health‑care centers where uninterrupted cold‑chain performance is critical despite limited grid‑electricity availability.

The HTXC‑240 model is an upright 4 °C blood bank refrigerator with 240 L (8.5 ft³) gross internal volume and an internal temperature range of 2 °C to 8 °C, suitable both for blood components and for pharmaceuticals and biological products that require refrigerated storage. The solar direct‑drive system works within an ambient temperature operating range of 5 °C to 43 °C, ensuring reliable performance even in hot climates or external‑exposure conditions. The upright cabinet implements a “first‑in, first‑out” (FIFO) stocking layout, simplifying bag rotation and reducing the risk of forgotten units stored at the rear of the chamber.

The interior features drawers constructed from stainless steel, which are corrosion‑resistant, easy to clean and compatible with hygiene requirements of blood banks, hospital laboratories and primary‑care clinics. The unit includes an automatic‑drainage design that collects and evaporates internal condensate without manual intervention, reducing maintenance workload and eliminating standing‑water zones that could promote microbial contamination. The system can be optionally equipped with a real‑time monitoring device (RTMD), enabling continuous temperature‑curve logging and integration with remote monitoring platforms, which is particularly useful for cold‑chain audits and public‑health programs in remote locations.

Diferenciais

Aplicações
This 4 °C solar direct‑drive blood bank refrigerator is suitable for small‑scale blood banks, fixed and mobile blood‑collection posts, rural health‑care facilities, vaccination sites, and small‑ to medium‑sized hospitals located in areas without stable grid‑power, where safe 4 °C storage of whole blood, blood components, and other temperature‑sensitive medical products is required. The combination of battery‑free solar operation, wide ambient‑temperature range, automatic drainage, and optional remote‑temperature monitoring makes it well‑adapted to public‑health programs, vaccination campaigns, and blood‑collection initiatives in geographically isolated regions, helping ensure cold‑chain integrity under challenging power‑supply conditions.

The unit is also appropriate for health‑care posts, emergency‑care units, and peripheral blood‑bank nodes that seek autonomous refrigeration solutions with low‑maintenance demands, leveraging existing or easily‑installed solar‑power setups without relying on large‑capacity generators or battery banks, thereby reducing operational costs and the risk of temperature excursions due to power‑supply interruptions.
