Dry ice. The focused clean agent.

ELSA — focused dry ice fire suppression Layered artwork: native 1774 by 887 scene, separate original 1039 by 281 Carver Fire logo, and outlined vector headline. Scene resolution at 48 inches wide is approximately 37 pixels per inch; this is not a final large-format print master. Created September 16, 2026 using built-in image_gen edits, then SVG composition with original logo.jpg and vector headline paths. Native scene: 1774 x 887 pixels. Original logo overlay: 1039 x 281 pixels. At 48 inches wide, the scene is 36.96 PPI; no artificial enlargement was performed. This is a reusable layered WEB hero, not a final 4x4 print board. High-resolution scene recreation or suitable detail-enhancement still needed before close-view print production. Headline outlines scale without font dependencies. The exact supplied logo is embedded separately rather than flattened into the scene. Final image edit prompt: Precise-object-edit. Edit this image in place. Preserve ELSA cabinet on left EXACTLY pixel for pixel: geometry, perspective, position, blue color, white ELSA lettering, nozzle, casters, all hardware unchanged. Preserve particle stream and navy space above. CHANGE ONLY fire on far right and floor. Replace unnatural neon linework flames with a photorealistic industrial fire photographed at high shutter speed: large flowing soft-edged translucent orange-yellow flame sheets, bright diffuse bases, darker orange turbulent tips, realistically lit charcoal smoke, natural uneven shapes, no repeated curly lines, no outlined or neon filament flames, no drawn flame texture. Fire remains restricted to rightmost quarter of image and does not obscure spray path. Floor should be dry matte concrete with soft fog and scattered dry ice, remove wet puddle-like mirror reflections. No text or logos added. No poster symbols or circles. 2:1 landscape. Output 3840x1920 or highest native resolution possible; preserve all requested product details.

How ELSA works

Concentrated cooling.
Local inerting. Focused delivery.

ELSA combines sand-sized dry ice with liquid nitrogen and directs the cryogenic discharge toward the hazard.

01 / TARGET

Deliver where needed.

A directed discharge concentrates the agent at the hazard, allowing protection to be planned around a defined area or asset.

02 / COOL

Remove heat.

Liquid nitrogen and solid CO₂ absorb heat as they change phase, bringing cryogenic cooling directly to the exposed area.

03 / INERT

Generate gas locally.

CO₂ and nitrogen gas displace oxygen near the discharge. The resulting effect depends on delivery, geometry, and ventilation.

The suppression media dissipate as gas, leaving no agent residue.

From concept to application

A system designed
around the hazard.

Start with the asset, exposure, and response objective. Then evaluate delivery, activation, placement, and service requirements.

Discuss system requirements
Suppression media
Dry ice and liquid nitrogen
Delivery
Fixed nozzle, flexible hose, or application-specific integration
Activation
Manual or automatic, based on the selected configuration
Controls
Industrial touchscreen PLC and active monitoring
Servicing
Review refill, tank-swap, and cryogenic supply arrangements for your site
Installation
Confirm capacity, footprint, utilities, ventilation, and access during application review
How does ELSA fit with existing fire protection?

ELSA is positioned as supplemental protection alongside required systems. The objective is early, targeted intervention that may avoid the need for water or foam discharge. System coordination and acceptance must be evaluated for the installation.

Can ELSA protect robots or energized equipment?

High-value equipment is an application focus. Compatibility must be evaluated for the actual equipment and exposure conditions, including cold, particle impact, condensation, and electrical operating state. The absence of agent residue alone does not establish compatibility.

What information helps assess an application?

Share the hazard, the equipment or materials at risk, the approximate area, existing fire protection, and what damage or downtime you are trying to prevent. Photos or a layout can help us begin a technical discussion.
