Liquid Oxygen Dispenser 800 Ltr (CRYO-800L-V-Oxygen)

Liquid Oxygen Dispenser Systems – Safe and Efficient Cryogenic Oxygen Management The Liquid Oxygen (LOX) Dispenser is a precision-engineered platform designed for safe handling, storage, and dispensing of cryogenic oxygen in medical, industrial, aerospace, and laboratory applications. Available in configurations such as LOX Dispenser 800L, mobile liquid oxygen systems, and towable LOX dispensers, these systems combine portability with high safety and operational efficiency. Key components include cryogenic oxygen tanks, vacuum insulated oxygen tanks, and stainless steel oxygen tanks, ensuring minimal heat ingress and low boil-off during storage. Advanced systems such as self-pressurizing LOX systems, Bestobell valve LOX systems, and high-pressure oxygen dispensers enable precise flow control and reliable dispensing. These dispensers support diverse applications including medical liquid oxygen dispensing, industrial oxygen dispensing, aerospace oxygen supply, and laboratory cryogenic operations. Additional platforms like oxygen cylinder filling stations, oxygen distribution units, and emergency oxygen supply systems provide flexible deployment for hospitals, industrial facilities, and field operations. Safety and compliance are ensured through ASME cryogenic dispensers, EN 13458 certified oxygen tanks, and cryogenic valve oxygen systems, while operational efficiency is enhanced by oxygen filling pump systems and oxygen dispensing trolleys for mobility and ease of use. The Portable LOX Dispenser series delivers high-capacity, reliable, and safe oxygen distribution, making it an essential solution for healthcare, industrial, aerospace, and laboratory environments requiring precise and continuous oxygen supply.

Introduction
Cryogenic liquid oxygen (LOX) dispensers are critical for safely storing and delivering high-purity oxygen at temperatures below −183 °C. The CRYO-800L-V-Oxygen system pairs an 800 L vacuum-insulated vertical vessel with a towable trolley, enabling easy relocation within hospitals, research labs, and industrial sites. By maintaining liquid oxygen at its boiling point, the dispenser minimizes vaporization losses (≤ 0.45% per day) and ensures on-demand availability for life-support, analytical, and process applications.

Design & Construction
• Double-Wall Vacuum Insulation: Two concentric vessels—a stainless-steel (SS-304) inner tank and an SS-304 outer jacket—create a high-vacuum annulus, often augmented with perlite or multi-layer insulation, to reduce heat ingress and boil-off.
• Structural Materials: All wetted and supporting components are Austenitic SS-304, chosen for cryogenic toughness, corrosion resistance, and compliance with ASME Section VIII and EN 13458-2:2002 standards.
• Towable Trolley: A robust frame with lockable heavy-duty casters and ergonomic handles allows safe maneuvering without specialized lifting equipment.

Key Features
• Self-Pressurizing Coil: A star-finned aluminum coil submerged in the liquid builds vapor pressure, enabling gravity-fed dispensing without external compressors.
• Economizer Function: Automatic pressure regulation maintains set delivery pressure, minimizing losses during low-rate withdrawals—critical for intermittent medical or laboratory demands.
• Low Evaporation Rate: Boil-off losses are kept below 0.45% per day through superior insulation and economizer control.
• Advanced Valving: Extended-spindle Bestobell cryogenic valves, full-port ball cocks (20 NB/15 NB), and dual safety relief valves with diverter ball valves ensure precise flow control and over-pressure protection.

Operation & Maintenance
1. Startup & Filling: Connect the supply line, open the inlet valve, and monitor fill level via the differential pressure gauge.
2. Pressurization: Engage the self-pressurizing coil; adjust economizer settings and relief valves to maintain target discharge pressure.
3. Dispensing: Open the outlet valve and full-port cock; activate the cylinder-filling pump for high-flow requirements.
4. Standby: Close all valves; maintain vacuum in the annulus to reduce boil-off.
5. Routine Maintenance: Inspect seals, gauges, valves, and relief devices quarterly; perform hydrostatic and pneumatic tests annually; verify bursting disc integrity per regulatory intervals.

Safety & Compliance
• Pressure Protection: Dual SRVs and a bursting disc prevent inner vessel over-pressurization.
• Standards Adherence: Manufactured per ASME VIII Div 1, EN 13458-2, and ISO 21010, ensuring materials and processes meet rigorous cryogenic service requirements.
• Leak & Burst Testing: Each unit undergoes 1.5× design pressure hydrostatic testing and pneumatic leak checks to guarantee structural integrity.
• Operator Training & Documentation: Comprehensive manuals and on-site training programs reduce risks associated with cryogenic handling and emergency procedures.
