Using water (R718) as a natural refrigerant, instead of chemical refrigerants.
ContactA breakthrough innovation developed by ALPINOV X, GEN5 leverages advanced expertise in the thermodynamic cycle of water to continuously cool complex and demanding infrastructures, with high energy efficiency, cost performance and reliability.
The water-powered cooling revolution
1% of the water (R718) drives the thermodynamic cycle
99% water = customer process fluid at setpoint temperature
Evaporation
During evaporation, 1% of the water changes state. The vapor absorbs heat before moving toward the compressor.
Compression
The water vapor is compressed, increasing its pressure so it can condense at ambient temperature.
Condensation
The vapor condenses, releasing the heat absorbed during evaporation. This heat can then be rejected or recovered depending on the application, while the cycle continues throughout chiller operation.
Closed-loop water cycle (R718) under vacuum
Water evaporates under vacuum, allowing its temperature to be lowered according to process requirements.
Fewer constraints, greater control, long-term performance.

A current model
under pressure
Industrial cooling is becoming harder to operate, optimize and perpetuate.
Conventional refrigerants are increasingly exposed to regulatory, economic and operational constraints:
- Regulatory: high GWP, PFAS-based products, and tight restrictions in Europe under the F-Gas and REACH regulations.
- Economic: rising prices, quotas, recurring costs tied to refrigerant management.
- Operational: pressurized systems, heavy maintenance, regular inspections.
Water-based cooling (R718) becomes a high-performance, sustainable alternative for critical industrial applications.
HISTORY & VISION
ALPINOV X reshapes industrial cooling
Founded in Grenoble (France) in 2017, ALPINOV X has pursued a clear ambition: to make industrial cooling more efficient, more reliable and more sustainable.
Our mission
We are developing a new generation of water-based chillers using water (R718) as a natural refrigerant, designed to meet the growing needs of global industry. Driven by a committed team and a shared culture of rigor, honesty and initiative, ALPINOV X is turning a breakthrough technology into an industrial solution ready for deployment.
An expert and robust industrial approach,
for market entry as early as 2026.
Several generations of functional prototypes, developed, tested and proven
Our unique expertise is built on advanced mastery of turbo-compression and vacuum water thermodynamic cycles, enabling us to overcome key technological barriers in industrial cooling.
Proven real-world performance that changes the standards
With a theoretical COP above 6 and measurable efficiency gains, GEN5 opens a new path for industrial cooling: more efficient, cleaner and free from conventional chemical refrigerants.
Scaling up toward industrialization
The third generation of chillers reached 500 kW of cooling power, validating the technology at a significant industrial scale. The next generation is designed to exceed 1 MW, confirming the solution's ability to serve high-power applications as early as 2026.
A chiller designed to reduce operational constraints
By eliminating chemical refrigerants and using an optimized architecture, GEN5 reduces maintenance operations, limits on-site constraints and supports long-term performance with fewer daily interventions. Industrial cooling becomes simpler, more reliable and easier to operate.
