Conservator Shutter
Mechanical Oil Containment & Fire Escalation Control
When a transformer incident occurs, uncontrolled oil flow from the conservator can dramatically worsen fire duration, damage and environmental consequences. The Conservator Shutter is a purely mechanical non-return valve designed to stop this escalation.

Why Conservator Isolation Matters
Uncontrolled oil feeds fires.
In many transformer incidents, the conservator from the main tank:
- supplying aditional oil to a fire.
- prolonging combustion
- increasing thermal stress on surrounding equipment.
- amplifying environmental damage.
Limiting fuel supply does not prevent the incident — it pretents the incident from becoming catastrophic.

What the Conservator Shutter Does
Mechanical, passive containment
In many transformer incidents, the conservator from the main tank:
- mechanically isolates the conservator from the main tank:
- prevents additional oil from feeding a fire.
- limits oil release in case of tank rupture, with or without ignition
- operates without electrical signals, sensors or external power.
The Conservator Shutter controls consquences — not sauses.

Typical Applications
The Conservator Shutter is typically applied where:
In many transformer incidents, the conservator from the main tank:
- Core Mechanical Protection
- Tactical Protection Systems
- Conservator Shutter.
- Large oil-filled power transformers
- Substations with environmental constraints
- Sites subject to strict fire prevention regulations.
The Conservator Shutter is always engineered as a compliment to SERGI’s core protection systems — naver as a stand-alone solution.
How it Fits Into SERGI's Architecture
Core Mechanical Protection
- Prevent catastrophic failure
Tactical Protection Systems
- Adapt to site constraints corstaints
Automatic Fire Detection
- Enable early response & damage Urnitation
