Rapidox SF6 6100 Pump Back - Gas Analyzer with Gas Return

Field SF6 quality analyzer with pump-back function — minimizes gas loss during HV equipment testing.

Description

The Rapidox SF6 6100 Pump Back is a premium, fully automatic SF6 gas analyzer from Cambridge Sensotec (United Kingdom) featuring a unique function that returns gas back into the equipment after analysis. It is a Zero Emission solution that minimizes losses of expensive SF6 gas and protects the environment.

Key Difference: Pump Back Function

What is Pump Back?

Pump Back is a built-in SF6 gas return system:

• Sampling — gas is drawn from the equipment
• Analysis — measurement of all quality parameters
• Return — clean SF6 is pumped back
• Result — minimal gas loss

Why is gas return needed?

Economic benefits

• SF6 is an expensive gas — priced up to $100+ per kg
• Loss minimization — return of up to 99% of gas
• Refill savings — fewer purchases of new gas
• Fast payback — within a few analyses

Environmental benefits

• SF6 is a greenhouse gas — 23,500 times more potent than CO2
• Zero Emission — zero emissions into the atmosphere
• Kyoto Protocol compliance — reduction of emissions
• Environmental responsibility — green technologies

Operational benefits

• No pressure drop — gas is returned to the system
• No equipment downtime — no refilling required
• Fast analysis — automatic cycle
• Safety — minimal gas handling
