Cambodia Automated Liquid Nitrogen Storage KGSQ

The Cambodia Automated Liquid Nitrogen Storage KGSQ is a self‑pressurizing cryogenic tank designed for safe storage of liquid nitrogen. Henan Tianzhidao Biological Technology Co., Ltd. manufactures the unit in the High‑Tech Industrial Development Zone of Zhengzhou, China. The tank automatically vaporises a small amount of nitrogen to raise internal pressure, enabling continuous drainage without external compressors. It incorporates double safety automatic control valves and a vent pipe to prevent pressure buildup beyond the critical limit.

Typical tanks of this class are constructed from stainless‑steel 304 and feature a vacuum‑insulated double‑wall construction that limits boil‑off to a standard 0.2 % per day. The pressure rating is usually 1.5 bar gauge, and the operating temperature is maintained at - 196 °C. Standard dimensions for a 100 L capacity model are approximately 600 mm × 400 mm × 800 mm (L × W × H). The device complies with EN 12405 safety standards and is often supplied with CE marking.

The system is widely used by research laboratories, medical facilities and agricultural research centres that require a reliable source of liquid nitrogen for sample preservation and cryogenic processes. Buyers typically request the tank together with compatible cryogenic dewars and a simple four‑valve control panel for pressurising, depressurising and releasing nitrogen. The listing does not disclose minimum order quantities, lead‑time or payment conditions, so these details should be clarified directly with Henan Tianzhidao Biological Technology Co., Ltd. Importers must also confirm any required certifications for cryogenic equipment in the destination market.

Henan Tianzhidao Biological Technology Co., Ltd. is located in the High‑Tech Industrial Development Zone of Zhengzhou, Henan, China, with the full address provided in the listing. The company holds a harbour trust tier, indicating a moderate level of platform verification, and its public response rate is currently zero.

The profile lists the manufacture of automated liquid nitrogen storage equipment but does not include information on production capacity, years of operation or specific client references. Prospective buyers should therefore request details on manufacturing tolerances, quality management systems and any third‑party test reports before finalising a purchase.
