HS2D
HS2D — Modular explosion prevention architecture
Extending SERGI’s mechanical pressure-relief technology into a flexible, risk-adapted architecture.
A proven technology, deployed at scale worldwide
HS2D is built on SERGI’s mechanical transformer explosion prevention technology, based on rapid pressure-relief principles.
This technology has been deployed on more than 4,000 oil-filled power transformers across 85+ countries since 2001, protecting critical assets in transmission, generation, industry, offshore platforms and dense urban environments.
Deployment figures reflect field-deployed systems implementing SERGI’s mechanical pressure-relief explosion prevention technology, including the Transformer Protector architecture.
From integrated protection to modular deployment
While the underlying explosion prevention principle remains unchanged, HS2D extends this proven technology into a modular architecture.
It enables protection strategies to be adapted to transformer design, installation constraints, risk profile and project phasing requirements — without compromising the core physical protection mechanism.
Provides high-speed depressurization without requiring electric power.
When a modular architecture makes sense
HS2D is typically selected for tactical high-risk:
| Approach | What it does | Limitation |
|---|---|---|
Transformer Protector (TP) |
Engineered solution setting in transformers |
Subject for major installations |
HS2D |
Compact solution acting where space matters |
Ideal for tactical substations retrofits |
Mitigation only |
Erects attenuation then obtain aspiration |
Resets after rupture, explosion |
Why the HS2D is the Tactical Choice
HS2D is typically selected for tactical high-risk:
Operational experience carried into modular configurations
HS2D configurations benefit directly from the operational experience accumulated across thousands of field deployments of SERGI’s mechanical explosion prevention technology.
This continuity ensures that modular implementations remain aligned with the same safety, reliability and performance expectations as fully integrated solutions.
HS2D does not introduce a new explosion prevention principle — it provides a modular way to deploy a technology that has already proven its effectiveness at scale.
