Description
The Rapidox 6100 QU4D Multi-Gas Pumpback is an advanced multi-gas analyzer from Cambridge Sensotec (United Kingdom) featuring the QU4D (Quad Upstream Dual) configuration, allowing simultaneous analysis of up to 4 gases. The instrument is equipped with a Pump Back gas return function to minimize emissions.
Purpose and Applications
What is the QU4D configuration?
QU4D (Quad Upstream Dual) is a unique sensor configuration:
| Characteristic | Description |
|---|---|
| Quad | 4 sensors simultaneously |
| Upstream | Direct gas flow |
| Dual | Dual analysis |
Advantages of QU4D
- Up to 4 gases — simultaneous analysis
- Modular configuration — tailored to the task
- Flexibility — sensor replacement
- Future upgrades — new gases
Application in the power industry
The Rapidox 6100 QU4D is used for:
- Comprehensive analysis — complete SF6 investigation
- Condition diagnostics — insulation assessment
- Decomposition detection — arcing by-products
- Special gases — analysis of unique impurities
Key Features
Analysis of up to 4 gases simultaneously
The QU4D configuration allows analysis of:
Base gases (SF6)
- SF6 — primary concentration 0-100%
- H2O — moisture (dew point -60°C to +20°C)
- SO2 — sulfur dioxide (decomposition product)
- H2S — hydrogen sulfide (decomposition product)
Additional gases (configuration-dependent)
- CO — carbon monoxide
- CF4 — carbon tetrafluoride
- O2 — oxygen
- N2 — nitrogen
- Other gases — upon customer request
Modular sensor configuration
- QU4D — 4 sensors (standard)
- QU2D — 2 sensors (basic)
- QU6D — 6 sensors (extended)
- Sensor replacement — by the user
Pump Back Function (Gas Return)
- Sampling — gas is drawn from the equipment
- Analysis — all quality parameters are measured
- Return — clean SF6 is pumped back
- Result — minimal gas loss
Advantages of Pump Back
Economic
- SF6 is an expensive gas — priced up to $100+ per kg
- Loss minimization — up to 99% gas return
- Refill savings — fewer new gas purchases
- Fast payback — within a few analyses
Environmental
- SF6 is a greenhouse gas — 23,500 times more potent than CO2
- Zero Emission — zero emissions into the atmosphere
- Kyoto Protocol compliance — emission reduction
- Environmental responsibility — green technologies
