Product Features & Benefits
High vacuum multi-layer thermal insulation
Greatly reduces external heat intrusion, minimizes evaporation loss, and saves you expensive gas consumption costs.
Multiple safety pressure relief protection
Equipped with main and auxiliary safety valves and bursting discs to ensure safe operation of the equipment in any abnormal overpressure situation and protect the safety of operators.
Built-in fully automatic vaporization system
It can directly supply constant temperature and stable gas without external vaporizer, simplifying the operation process and saving space.
High-precision VGL float level gauge
Real-time and accurate display of internal residual liquid volume to prevent sudden gas depletion from affecting production progress.
Application Scenarios
- Industrial welding and cutting: Provide high-purity shielding gas for laser cutting machines and plasma welding.
- Laboratory research: low temperature physical experiments, superconductivity research and biological sample preservation.
- Health care: hospital liquid oxygen supply systems to support respiratory therapy.
- Electronics Manufacturing: Atmosphere Protection in Semiconductor Production.
- Animal husbandry: cryopreservation and transport of semen at low temperature.
Packaging & Shipping
- Internal protection: The surface of the Dewar bottle is wrapped with thickened bubble film to prevent scratches.
- Reinforced packaging: Use export-grade wooden pallets or fumigation-free wooden boxes, fixed vertically.
- Anti-collision protection: add shockproof gasket at the bottom, worry-free long-distance shipping.
- Transportation mode: Support sea (FCL/LCL), air and land transportation, and cooperate with world-renowned freight forwarders for a long time.

FAQ
Q1: What gases can be stored in a 499L Dewar?
A1: Supports liquid oxygen (LO2), liquid nitrogen (LN2), liquid argon (LAr), liquid carbon dioxide (LCO2) and LNG.
Q2: Does your dewar flask have CE or ASME certification?
A2: Yes, our Dewar bottles are fully compliant with ISO9001 and CE certification, and ASME certification can be provided according to demand.
Q3: How much gas will be lost naturally after the welded insulated cylinder is filled?
A3: Under normal ambient temperature, the daily evaporation rate is lower than 1. 6%, and the vacuum performance remains excellent.
Q4: What is the air output of the built-in vaporizer?
A4: The standard configuration usually supports continuous traffic of 10-20 m ³/h, which can be enhanced according to customer needs.
Q5: How long is the warranty period of vacuum dewar?
A5: We provide a 1-year warranty for the main body of the Dewar bottle and a 2-3-year long-term guarantee for the vacuum.
Q6: Does it support OEM custom colors or logos?
A6: Support. We can customize paint colors and printed logos according to your brand requirements.
Q7: What should I do if the vacuum is damaged after receiving the goods?
A7: All liquid dewar cylinders are rigorously tested before leaving the factory. If damage is caused by transportation, we will provide free replacement or repair support.
Q8: Is the level gauge of VGL dewar easily damaged?
A8: We use thickened shields and high-strength floats, which have excellent shock resistance and are rarely damaged during normal operation.
Q9: What is the minimum minimum order quantity (MOQ)?
A9: The minimum order quantity is 1 set, welcome to purchase in batches, and the price is better.
