PATENTED · DEPLOYED · READY FOR OEM INTEGRATION
A breakthrough in cooling architecture that redefines what a compressor cycle can deliver.
More cooling.
Less power.
Noditech holds granted patents covering core elements of its system architecture for compressor-driven cooling. The solution has already been implemented. The current phase is integration and rollout on global OEM platforms.

Who we are
A Swedish technology owner in compressor-driven cooling
Noditech is a small, technically led company in Sweden. We do not sell cooling units and we do not run installations. We own and develop a patented system architecture for compressor-driven cooling, prove it in matched measurements, and bring it to market through licensing, system integration and design-in with established global OEMs.
- Granted patents on core elements of the architecture
- The solution has already been implemented
- Current phase: integration and rollout on global OEM platforms
Technology
A new operating regime, not a new machine
Where the gain comes from
Vapour-compression cooling has run in essentially the same regime for decades, and remaining gains have come in single percentage points from compressors and controls. Noditech reworks the circuit itself, from the expansion side into the evaporator.
What it applies to
The architecture is scalable and applies to air-cooled and liquid-cooled water chillers as well as air-to-air units, and works inside conventional architectures rather than replacing them. Our focus so far has been air-based units. The architecture is deployment-ready on air-to-air units; accredited matched testing of the air-to-liquid line is the remaining verification step.
Why it holds
The advantage sits in the interaction between the architecture, the granted patents, non-public control knowledge, and the integration data every comparable run adds.
Evidence
What has actually been measured
In a documented air-to-air comparison reviewed by AFRY, a selected configuration delivered 28% more cooling at the same electrical input. The result is configuration-specific and does not constitute a universal performance guarantee for other systems.
- Air-to-air, matched comparison
- +28% cooling at the same electrical input
- Two units operated simultaneously in the same cold room on the same electricity baseline. Test data reviewed by AFRY.
- Test boundary
- One selected configuration
- Configuration-specific; not transferable to other systems without a platform-specific baseline.
- Scalability and applicability
- Chillers and air-to-air units
- The same principle applies to air-cooled and liquid-cooled water chillers and to air-to-air units; work so far has been on air-based units.
How we talk about numbers: absolute efficiency always depends on the solution, the duty point and the ambient conditions, so we do not publish single-point figures. What we state is the relative advantage in one matched comparison — and that accredited, matched testing of the air-to-liquid line is the next step, reported whatever it shows.
Why efficiency is the bottleneck
Cooling is where scarce electricity goes
One bottleneck at global scale: cooling is a large and growing share of electricity demand in data centres, industrial process cooling and comfort cooling alike, and efficiency is the only lever that releases capacity without building more of it.
Data centres get the headlines, but comfort cooling grows on the same curve — and both run on the same compressor cycle. One efficiency step, two of the fastest-growing electricity loads on the planet.
Who it is for
Two ways to work with us
OEMs and system manufacturers
For cooling and HVAC manufacturers and integration partners evaluating a patented and implemented system architecture for their own air-to-air and air-to-liquid product platforms. The process starts by defining the target platform, operating conditions, integration scope and the requirements for a matched OEM evaluation.

One regional driver: the EU market from 1 January 2027
From 1 January 2027, Regulation (EU) 2024/573 prohibits placing on the EU market stationary chillers above a rated capacity of 12 kW that contain, or whose functioning relies upon, fluorinated greenhouse gases with a GWP of 750 or more, except where required to meet safety requirements at the site of operation. The provision concerns new equipment placed on the market, not a general prohibition on continuing to operate existing installations.
- Applies to new equipment placed on the EU market, not to existing installations
- Threshold: stationary chillers above a rated capacity of 12 kW, GWP 750 or above
- Propane has a GWP of approximately 3 and is below the 750 threshold in this provision. Other applicable safety and product requirements still apply.
Regulation (EU) 2024/573, Article 11(1) and Annex IV, point 7(d).
The EU market is one regional driver among several; the case for efficiency is global. This regulatory summary is provided for orientation only.
