Liquid Nitrogen Supply Dewar

The Liquid Nitrogen Supply Dewar is designed to provide a reliable on-site reserve of liquid nitrogen for livestock breeding and cryogenic storage operations. It can be used to replenish semen storage tanks, embryo storage tanks and other compatible LN2 equipment when required.

The vessel uses a vacuum-insulated structure to reduce heat transfer and limit unnecessary liquid nitrogen evaporation. A strong, lightweight aluminum construction provides a practical balance between durability, portability and handling convenience.

For commercial pig farms, breeding groups and agricultural engineering projects, the dewar can be positioned in a dedicated genetics, artificial insemination or veterinary service area as part of the farm's cryogenic supply system.

• Vacuum-insulated construction helps reduce heat transfer and liquid nitrogen consumption.
• Lightweight aluminum body facilitates routine handling and movement within the farm facility.
• Durable outer construction is suitable for professional livestock breeding and agricultural environments.
• Efficient LN2 storage provides a practical reserve for topping up cryogenic storage equipment.
• Flexible dispensing can support manual pouring or compatible withdrawal accessories.
• Compact footprint allows convenient placement in dedicated breeding or service areas.
• Multiple capacity options can support different farm sizes and liquid nitrogen consumption levels.
• Project-oriented configuration allows accessories and handling arrangements to be selected according to application requirements.

• Outer shell: Strong metal housing designed to protect the internal cryogenic vessel during routine handling.
• Inner reservoir: Dedicated vessel for liquid nitrogen storage.
• Vacuum space: Insulating layer between the inner and outer vessels that limits heat transfer.
• Neck tube: Low-heat-transfer connection between the inner reservoir and upper opening.
• Insulated lid or cap: Helps reduce heat ingress through the storage opening.
• Handles: Provide convenient grip points for controlled manual movement.
• Dispensing interface: Can accommodate suitable pouring, dipping or withdrawal accessories according to configuration.
• Protective base: Provides stable support when the dewar is positioned on the floor or another suitable working surface.

Liquid nitrogen is retained inside the inner reservoir. The vacuum space between the inner and outer vessels acts as thermal insulation, reducing heat transfer from the surrounding environment and helping slow LN2 evaporation.

When a semen tank or other compatible cryogenic vessel requires replenishment, liquid nitrogen can be transferred from the supply dewar using an appropriate dispensing method or accessory. This provides a practical on-site source of LN2 for routine cryogenic equipment management.

Actual evaporation rate and holding time depend on the selected model, ambient conditions, filling level, frequency of opening and operating practices.

Technical values should be confirmed against the final model and configuration before procurement.

The Liquid Nitrogen Supply Dewar is suitable for cryogenic supply and livestock reproductive management applications, including:

• Commercial pig farms and integrated swine production systems
• Boar stations and livestock breeding centers
• Artificial insemination and genetics facilities
• Frozen semen storage operations
• Embryo storage and embryo transfer facilities
• Veterinary reproductive service areas
• Livestock genetic improvement projects
• Agricultural engineering and farm construction projects requiring an LN2 supply system

Configuration can be adapted for livestock breeding farms, agricultural engineering companies, distributors and overseas project procurement.

• Storage capacity: Customizable
• Neck and opening configuration: According to project requirements
• Dispensing accessories: Available upon request
• Handles and mobility accessories: Customizable according to model
• Product identification and labeling: Customizable
• Export packaging: According to project requirements
• Environmental adaptation: Designed according to local climate and farm conditions

Installation: The dewar is normally used as a floor-standing or movable supply vessel and does not require permanent connection to the pig house, steel structure building or farm building.

Placement: Install on a stable, level surface in a clean, dry and well-ventilated area. Sufficient clearance should be provided for filling, dispensing, inspection and routine movement.

Maintenance: Regularly inspect the outer vessel, lid, neck area and accessories for physical damage or abnormal frost formation. Keep the vessel clean and dry and monitor LN2 levels according to the operating schedule.

Safety: Liquid nitrogen is an extremely cold cryogenic liquid and may cause severe cold burns or oxygen displacement in poorly ventilated spaces. Appropriate cryogenic PPE, safe handling procedures and adequate ventilation are required.

Q1: What is a liquid nitrogen supply dewar used for?

It is primarily used to store liquid nitrogen and supply LN2 to compatible semen tanks, embryo storage tanks and other cryogenic equipment.

Q2: Can it be used on commercial pig farms?

Yes. It can serve as an on-site LN2 reserve for artificial insemination, genetics, semen storage and other reproductive management operations.

Q3: Does the dewar need to be connected to a building?

Normally, no. It is generally operated as a standalone floor-standing or movable cryogenic vessel.

Q4: How is liquid nitrogen transferred from the dewar?

Depending on the selected configuration, LN2 can be transferred by controlled manual pouring or through a compatible dispensing device, dipper or withdrawal accessory.

Q5: How should the capacity be selected?

Capacity should be based on the number and size of cryogenic storage tanks being replenished, LN2 consumption, refill frequency and available operating space.

Q6: Can the supply dewar be customized for an agricultural project?

Yes. Capacity, dispensing accessories, handling configuration and packaging can be arranged according to project requirements.
