Industrial Dewar BNC-F series

laboratoryfor the pharmaceutical industryfor the food industry

Overview
Self-pressurized BNC-F series liquid nitrogen containers use vaporization of a small amount of liquid nitrogen to build pressure, enabling automatic discharge and transfer to other containers. They are designed for transport and storage of liquid nitrogen and serve as a cold source for refrigeration devices. Stainless-steel construction reduces evaporation losses. Standard fittings include a pressure-building valve, liquid valve, release valve and pressure gauge; models over 200 L also include a bursting disc and muffler. All models feature four bottom casters for mobility. SKU: BNC-F Series

PRODUCT QUALIFICATION
CE certificate; National cryogenic container quality supervision and inspection center.

APPLICATION RANGE
Primarily used for storage of liquid nitrogen and for filling other containers. Common applications: mold industry, animal husbandry, pharmaceuticals, semiconductors, food processing, low-temperature chemistry, aerospace, military and related fields.

Liquid Nitrogen Containers Product Features

• Ergonomic design for easy operation by personnel
• Equipped with high-quality American cryogenic valves
• Special neck design for ultra-low evaporation rate
• Optional transport cart for easier handling
• Optional monitoring system to display level and pressure data
