Fig · 02 800 L SS-304 vessel, Bestobell valve manifold and towable trolley base

Two concentric SS-304 vessels — an inner tank and an outer jacket — create a high-vacuum annulus, augmented with perlite or multi-layer insulation held to ≤100 microns, to minimize heat ingress and keep boil-off below 0.45% per day. A star-finned aluminum coil submerged in the liquid builds vapor pressure, enabling gravity-fed dispensing without external compressors, while an economizer function automatically regulates delivery pressure to minimize losses during low-rate withdrawals.

Extended-spindle Bestobell cryogenic valves, full-port ball cocks (20 NB/15 NB), and dual safety relief valves with a bursting disc provide precise flow control and over-pressure protection. The heavy-duty towable trolley — lockable casters and ergonomic handles — allows relocation without lifting equipment.

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.

Research & laboratories: precise cryogenic delivery for analytical instruments, cryobiology, and materials science experiments.
Aerospace & defense: ground-support oxygen refilling for aircraft systems, rocket test stands, and environmental simulation chambers.

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.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 What is the Liquid Oxygen Dispenser 800 Ltr (CRYO-800L-V-Oxygen)?

The CRYO-800L-V-Oxygen is an 800-litre, vacuum-insulated, vertical liquid oxygen dispenser mounted on a towable trolley, designed and manufactured by Neometrix Engineering Pvt Ltd, India, for safe cryogenic oxygen storage and dispensing in medical, industrial, aerospace and laboratory settings.

Q · 02 What is the working pressure of the CRYO-800L-V-Oxygen dispenser?

The vessel carries a maximum allowable working pressure of 17 kg/cm² g (approximately 1.67 MPa), with a vacuum-corrected design pressure of 18.633 kg/cm² g. Each unit is hydrostatic-tested at 1.5× design pressure before shipment.

Q · 03 How low is the boil-off rate on the 800 L LOX dispenser?

Double-wall vacuum insulation, augmented with perlite or multi-layer insulation held to ≤100 microns vacuum level, keeps boil-off losses below 0.45% per day, so stored liquid oxygen stays available for on-demand dispensing with minimal vaporization loss.

Q · 04 How does the dispenser deliver liquid oxygen without external compressors?

A star-finned aluminum self-pressurizing coil submerged in the liquid builds vapor pressure inside the vessel, enabling gravity-fed dispensing. An economizer function automatically regulates delivery pressure during withdrawals to minimize losses during intermittent medical or laboratory demand.

Q · 05 What valves and safety devices does the CRYO-800L-V-Oxygen use?

The system uses extended-spindle Bestobell cryogenic valves and full-port ball cocks (20 NB/15 NB) for precise flow control, plus two safety relief valves and a bursting disc to prevent inner-vessel over-pressurization.
