Product Overview

MINGXIN’s Cryogenic Insulated Cylinders (often referred to as Dura Cylinders or Liquid Dewars) are advanced, portable storage solutions designed for the highly efficient handling and distribution of cryogenic liquids, including Liquid Nitrogen (LN₂), Liquid Oxygen (LO₂), Liquid Argon (LAr), Liquefied Natural Gas (LNG), and Liquid Carbon Dioxide (LCO₂). Offering superior thermal insulation and premium safety features, these cylinders are engineered to ensure minimal evaporation loss, providing a reliable and continuous gas or liquid supply for the industrial, medical, and energy sectors.

Key Features & Design Highlights

  • High-Efficiency Insulation: Engineered with state-of-the-art vacuum multi-layer super insulation technology, which reduces the daily evaporation rate to industry-leading levels (as low as ≤1.15%), ensuring zero product waste during storage and transport.

  • Premium Stainless Steel Construction: Manufactured with a full 304 stainless steel body (inner and outer vessels), ensuring exceptional durability, strict hygiene for medical use, and supreme corrosion resistance in harsh environments.

  • Rugged & Mobile Design: Features an integrated protective frame (available in wheeled or stationary configurations) that enables effortless maneuverability while safeguarding the cylinder against impact damage.

  • Precision Monitoring: Equipped with upgraded, high-accuracy liquid level gauges (digital or mechanical options available) to provide operators with real-time volume monitoring.

  • Uncompromising Safety: Built with a comprehensive safety relief system, including dual safety valves (specifically optimized for LNG), burst discs, and explosion-proof devices to strictly comply with international safety regulations.

Technical Specifications

  • Available Models: Vertical configurations (DPL450 / DPL700 / DPL900) and Horizontal configurations (DPW650).

  • Volume Capacity: Geometric volumes ranging from 110 Liters to 1,000 Liters, bridging the gap between small high-pressure cylinders and large bulk tanks.

  • Working Pressure: Highly customizable pressure ratings, ranging from 1.44 MPa to 3.79 MPa, available in Medium Pressure (MP), High Pressure (HP), and Ultra-High Pressure (VHP) models.

  • Gas Flow Rate: Built-in vaporizer allows for continuous gas flow ranging from 4 to 85 Nm³/H (O₂/N₂/Ar), eliminating the need for external gasification equipment.

  • Certifications: Manufactured in strict accordance with GB, ASME, CE, and CCS standards to guarantee global market compliance.

Industry Applications

  • Industrial Gas Supply: Provides a reliable, high-purity, and centralized gas supply for laser cutting, welding, metal fabrication, and chemical processing (replacing the hassle of handling dozens of high-pressure cylinders).

  • Medical & Research: The preferred choice for medical-grade Liquid Oxygen (LOX) supply in hospitals, clinics, and biological cryopreservation laboratories.

  • Energy Sector: Serves as a portable fuel tank for LNG refueling, marine engines, and remote natural gas distribution.

  • Food & Beverage: Delivers LCO₂ and LN₂ for rapid food freezing, cold chain logistics, and beverage carbonation systems.
