HS2D

Compact Depressurization Device for Tactical Transformer Protection

HS2D provides engineered mechanical protection against transformer explosion and fire.
It is compact, passive, and non-electric — particularly adapted for retrofits and constrained layouts requiring a pragmatic last line of defense.

A Tactical Last Line of Defense

Compact, modular and fast-acting, HS2D is the depressurization device engineered to adapt to tactical protection needs.

Compact by Design

Fits in tight layouts such as distribution centers and urban substations

Retrofittable & Modular

Easily integrated on existing transformers of all ages and types.

Tactical Game-Changer

Provides high-speed depressurization without requiring electric power.

Provides high-speed depressurization without requiring electric power.

Where the HS2D Protects Best

HS2D is typically selected for tactical high-risk:

Distribution Substations

Specifically in dense urban areas

Easy retrofit and short lead time

Quickly upgrade transformers without major modifications

Independently detects dynamic pressure rise

Acts autonomously, within milliseconds
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:

Compact & non-electric design

Built for urban, constrained and sensitive sites

Easy retrofit and short lead time

Quickly upgrade transformers without major modifications

Independently detects dynamic pressure rise

Acts autonomously, within milliseconds

Cost-effective tactical last line of defense

Offers an optimal solution where asset replacement is restricted
