Technical Highlights
01
Unique subcooling chamber design:
The system contains a patented subcooling chamber structure. Through precise temperature-control technology, it maintains LNG in a low-temperature liquid state and suppresses pre-vaporization caused by environmental heat penetration before sampling, ensuring sample authenticity from the source.
02
Rapid flash vaporization and full mixing technology:
A multi-stage swirl mixing unit integrated with a flash chamber enables rapid and uniform vaporization of LNG samples, avoids component stratification, ensures sufficient gas-liquid mixing, and improves subsequent analysis accuracy.
03
High-power oil-bath heating with no dead zone:
Equipped with a high-power oil-bath circulating heating system. Three-dimensional flow-channel optimization achieves uniform heat-field distribution, eliminating local overheating or cold zones found in traditional electric tracing and ensuring consistent sample heating throughout the process.
04
Dual-chamber isolation against heat conduction:
The subcooling chamber and heating chamber are physically isolated. Combined with a vacuum insulation layer design, it completely blocks reverse heat-conduction paths, avoids thermal interference from high-temperature zones to low-temperature samples, and ensures independent temperature-control accuracy of both chambers.
05
Throttling orifice resistant to pre-vaporization interference:
Innovative throttling-orifice structure optimizes fluid dynamics. Precise matching of pressure drop and flow velocity suppresses premature LNG vaporization in the sampling line and reduces the impact of phase change on component representativeness.
06
Maintenance-free reliability design:
The entire system has no mechanical moving parts and uses integrated forming of ultra-low-temperature-resistant alloy, avoiding wear and leakage risks, reducing failure rate, and enabling long-term maintenance-free operation.
07
Lightweight portable structure:
Through compact layout and aerospace-grade lightweight materials, equipment volume is reduced by 40% and weight by 50% compared with traditional solutions. It supports handheld or embedded installation without additional brackets, adapting to complex spaces.
