Import Congo Self-Pressurized Liquid Nitrogen Tank Kgsq — Buy in Bulk from Supplier in China

The Congo Self-Pressurized Liquid Nitrogen Tank KGSQ is a dual-wall vacuum-insulated vessel designed to store and discharge liquid nitrogen through internal pressure generated by vaporization. It operates without external pumps or gas sources, relying on the natural boil-off of liquid nitrogen to maintain pressure for controlled dispensing. The tank is constructed with high-strength aluminum alloy and features a double-layered vacuum jacket to minimize evaporation loss, typically below 0.5% per day under standard conditions.

This model follows standard industry design for self-pressurizing nitrogen tanks, with a typical working pressure range of 0.05 to 0.15 MPa and a safety relief valve set at 0.18 MPa. The internal booster pipe is made of 304 stainless steel to resist cryogenic embrittlement, and the outer shell is coated with a powder-finished epoxy to prevent corrosion. Standard capacities for this series range from 50 to 300 liters, with the KGSQ variant commonly available in 100L and 150L sizes. The tank is not rated for pressurized gas storage beyond liquid nitrogen and must not be used with other cryogens without manufacturer verification.

These tanks are primarily purchased by biomedical research labs, fertility clinics, and agricultural cryopreservation facilities that require portable, reliable liquid nitrogen delivery without external power. Buyers typically require a minimum order quantity of one unit for direct shipment, with bulk discounts available for orders of five or more. Delivery is usually FOB Zhengzhou Port, with packaging secured in a wooden crate to prevent impact damage during transit. Lead time is typically 15 to 25 days after order confirmation, subject to production scheduling.

Henan Tianzhidao Biological Technology Co., Ltd. is a manufacturer based in Zhengzhou, Henan Province, specializing in cryogenic equipment for biological and laboratory use. The company's address is listed in the High-Tech Industrial Development Zone of Zhengzhou, indicating a registered industrial facility. The supplier has been verified by a harbor-tier trust system, suggesting a documented business registration and physical presence, though no public certification records or third-party audit reports are provided in the listing.

The supplier's response rate and average response time are recorded as zero, indicating no recent buyer communication activity on the platform. This does not confirm operational capacity but suggests potential delays in customer service responsiveness. The company's product focus appears limited to liquid nitrogen storage and transfer systems, with no evidence of broader product lines or export history beyond this model. There is no claim of ISO certification, production volume, or client list provided in the source data.
