Product Advantages

1.Lightweight design, lower tare weight for same volume, higher LOX payload and long-term fuel saving;

2.Stable vacuum insulation, steady boil-off performance to reduce LOX loss;

3.Mass-produced standard model, faster delivery time;

4.Universal valves & chassis spare parts, easy local procurement & simple maintenance;

5.Full pressure & air tightness test, basic certificates for most countries import.

Cryogenic tanker trailers applications

1.Industrial Gas Distributors: Bulk distribution and filling of liquid oxygen

2.Medical Oxygen Supply Systems: Replenishment of liquid oxygen storage tanks at large hospitals

3.Metalworking and Welding: Supply of liquid oxygen for cutting and welding applications

4.Aerospace: Transport of propellant-grade liquid oxygen

5.Air Separation Plants: Outbound transport of liquid oxygen products

6.Steel Mills and Glass Plants: Supply of liquid oxygen for oxygen-enriched combustion systems

Operation Notes:

1.LOX is strong oxidizer. No oil, grease or open fire in loading zone;

2.Operators wear cryogenic gloves and goggles to prevent cold burn;

3.Filling level ≤90% tank volume for thermal expansion;

4.Check pressure, grounding and valves before every trip;

5.Regular vacuum inspection. Vacuum decay will increase BOG boil-off;

6.Avoid long time direct sun exposure and monitor tank pressure.

Troubleshooting

Frequently Asked Questions	probable cause	Solution
daily evaporation rate increased	Decrease in vacuum	Check the vacuum nozzle and make up the vacuum if necessary
safety valve opening	Liquid level overfull or pressure set low	Filling rate ≤ 95%, check the safety valve
Low pump unloading efficiency	Insufficient pre-cooling of pump or clogged lines;	Extend the pre-cooling time, check the filter
pipeline frosting abnormal	Local failure of vacuum insulation	Contact the manufacturer to evaluate the maintenance plan
valve difficult to operate	Shrinkage or icing of seals at low temperatures	Use special low temperature lubricant and check the seal
Level gauge reading abnormal	Sensor failure or icing	Calibrate or replace the liquid level sensor
