REFRIGERANT-FREE • COMPRESSOR-FREE • ENERGY-GENERATING
Cooling that generates
its own electricity.
Unitech turns cooling's waste heat into the electricity that runs it with no refrigerant, no compressor and no moving parts in the cooling circuit.

01 - THE PROBLEM
Cooling pays twice.
Once for the electricity. Again for the refrigerant.
Every cooling system consumes power to create cold, then spends more energy rejecting the heat it creates. The refrigerants it relies on are also being phased down worldwide.
10%
of global electricity is consumed by cooling

The industry does not need a better refrigerant. It needs a different cooling cycle.
The Solution
TOVENVOR · INIJEVID
We rebuilt cooling from first principles fluid dynamics and energy recovery in place of chemistry and compression. No refrigerant. No compressor. No moving parts in the cooling circuit.
TOVENVOR uses a toroidal venturi system to produce cooling through controlled pressure differentials. Ranque–Hilsch vortex tube, a device with no moving parts and no working fluid, where it forms a high-speed vortex, fast enough that it separates itself into two: one cold, one hot. The cold stream returns to the space as cooling.
The hot stream is where every other system stops, venting it to the outside air. We send it into INIJEVID, our induced-impingement jet viscous drag turbine, which captures that rejected heat and converts it back into electricity that runs the load.
Two outputs where every other system gives one: cold air to the space, power to the building.
Measured coefficient of performance of 3.5–4× in laboratory testing, with thermodynamics validated in collaboration with Cranfield and Aston Universities.
Introducing Freecool Technology
COOLZE
Use Cases
Where it applies
One platform, licensed to manufacturers across every scale of cooling.
Data Centres
Half the power drawn leaves as heat. Cooling is one of the largest loads in a data hall, and almost everything it removes is vented outside. TOVENVOR · INIJEVID returns that energy to the facility instead and a pilot system is running at a data centre in Kyiv now.
Industrial Refrigeration
Cold storage without the chemical liability. Process cooling and cold chain depend on refrigerants facing international phase-down, with disposal costs waiting at end of life. Ours uses none, removing F-Gas exposure from the balance sheet entirely.
Commercial HVAC
The building's biggest load, working twice. Offices, retail and hospitality carry cooling as one of their largest operating costs and one of their largest carbon lines. Recovering the rejected heat addresses both at once.
Unitech does not manufacture. We license the platform to OEMs and share in the savings it creates.
Coolze
The Technology, in your hands
Coolze applies the same physics in a product you can hold. Its patented Freecool technology delivers affordable, zero-emission cooling that needs no refrigerant and no connection to the grid, bringing independent cooling to the households and regions the grid does not reach.
Cooling accounts for around 6% of global climate emissions. Coolze is named for its zero-emission nature: cooling that does not come at the planet's expense, and proof that the platform works outside the laboratory
Coolze has developed groundbreaking patented technology called 'Freecool' that offers affordable, zero-emission, and non-grid-connected independent cooling solutions to the world. Our innovative approach aims to address the pressing challenges of global cooling needs while significantly reducing environmental impact.
Coolze is not just a product; it's a commitment to sustainability. With 6% of all global climate change emissions attributed to cooling, it's imperative to embrace eco-friendly solutions. Coolze is aptly named for its zero-emission nature, offering cooling solutions without compromising the health of our planet.

Grant statement
Backed by Innovate UK. Built with Cranfield and Aston.
We are proud to be supported by Innovate UK through the EcoVenturi programme, developing refrigerant-free cooling and refrigeration for a lower-carbon future. The thermodynamics behind the system have been developed and validated in collaboration with Cranfield University and Aston University, with Enigmasoft Technologies as our engineering partner.
A pilot system is now running at a data centre in Kyiv, delivering cooling and returning recovered electricity to the facility. Independent performance data follows in 2026/27
