An electricity-free refrigeration unit powered by ionochaloric endothermic chemistry — reusable, scalable, and built for the places where reliable cold storage can save lives.
Thermavault is an electricity-free refrigeration unit that works on ionochaloric endothermic chemistry. No compressors. No grid dependency. No emissions during operation. Just reliable cold, wherever it's needed.
Unlike conventional refrigeration, Thermavault requires no continuous power supply. It is reusable across cycles and designed to scale — from a single portable unit to large cold chain deployments.
Built for two core applications: the cold chain industry, where temperature integrity is critical for vaccines and medical supplies, and the everyday user who needs a portable, electricity-free refrigeration solution.

BUILT FOR THE REAL WORLD
01
Medical Cold Chain
Vaccines, insulin, blood samples, and biological specimens require strict temperature control. Thermavault delivers reliable cold storage in clinics, field hospitals, and last-mile distribution points where consistent power cannot be guaranteed.
02
Irregular Power Supply
In regions with unreliable grid access or frequent outages, Thermavault acts as a thermal battery — charged during available power windows and maintaining temperature passively for hours afterward. A true buffer against blackouts.
COLD STORAGE WITHOUT A POWER CORD.
Access to reliable cold storage is not a luxury — it is infrastructure. It determines whether vaccines remain viable, whether medicine reaches patients intact, and whether families in off-grid communities have access to basic cold chain services.
Thermavault runs on ionochaloric endothermic chemistry, not electricity. It needs no grid, no compressor, and no fuel. We are in active prototyping, refining the product for the real-world conditions it will face.
Prototype Stage — Active Development
Thermavault is currently in active prototyping. We are not yet commercially available, but we welcome inquiries, partnerships, and research collaborations.
→ Who We Are
ABOUT US
We built a fridge that doesn't need a plug.
Thermavault started with a simple, uncomfortable question: why does reliable cold storage still require electricity — a resource that billions of people cannot count on?
Our answer is an electricity-free refrigeration unit powered by ionochaloric endothermic chemistry. No compressor. No grid connection. No fuel. Thermavault absorbs heat through a controlled chemical reaction, maintaining stable refrigeration temperatures without drawing a single watt of power.
It is reusable, scalable, and designed from the ground up for the conditions most refrigeration products were never built to handle. We are a small, focused founding team currently in active prototyping — building toward a product that works as reliably in a field clinic as it does in a city.
01
No Electricity Required
Powered entirely by ionochaloric endothermic chemistry. Zero grid dependency, zero operational emissions.
02
Reusable by Design
Built for repeated use across many cycles. Not a single-use solution — a durable piece of cold chain infrastructure.
03
Scalable Architecture
One unit works. Many units work together. Thermavault scales to meet the demands of small clinics and large deployments alike.
04
Built for the Real World
Remote villages, field hospitals, off-grid communities. Designed for where it actually needs to work, not just where it's convenient.

WHERE THERMAVAULT WORKS
01
Cold Chain Industry
Vaccines, insulin, diagnostics, and biological specimens require strict temperature integrity from source to patient. Thermavault provides reliable, electricity-free refrigeration for last-mile cold chain distribution — where grid power is unreliable or absent entirely.
02
Portable Refrigeration
For end users who need cold storage on the move — campers, travellers, rural households, and field workers. Thermavault functions as a portable refrigerator that needs no socket, no generator, and no fuel. Cold storage, untethered.

THE PRODUCT
THERMAVAULT
Gen-1 Prototype — Electricity-Free Refrigeration Unit
Thermavault is an electricity-free refrigeration unit. It produces and maintains cold through an ionochaloric endothermic reaction — a controlled chemical process that absorbs heat without requiring any electrical input. No compressor. No plug. No emissions during operation.
The unit is reusable across multiple cycles and designed to scale from a single portable unit to larger cold chain deployments. It is built for the conditions where conventional refrigeration consistently fails.
⬡
Electricity-Free Operation
Powered entirely by ionochaloric endothermic chemistry. Requires no grid connection, no generator, and no fuel to maintain cold.
◎
Reusable Across Cycles
Designed for repeated use. Not a single-use cold pack — a durable refrigeration unit engineered for long-term deployment.
▣
Scalable Architecture
Units are designed to work independently or together. Scale to the size of the deployment, without complex infrastructure changes.
◈
Portable Form Factor
Compact enough to carry to a field clinic or take on the road. Purpose-built for environments where refrigeration has historically been unavailable.
