Aqua runs on transcritical CO₂ (R744) and delivers heating, cooling and domestic hot water from a single unit, at supply temperatures up to 90°C and return temperatures up to 50°C.

Five models cover 30 to 280 kW each, scalable in parallel from 17 kW to 2.5 MW. Every unit is skid mounted, 68 to 89 cm wide, and fits through a standard doorway.

We spent seventeen years inside commercial CO₂ refrigeration before we drew the first Aqua unit. Watch how that experience became a standardised platform, and why the CO₂ cycle can now do a boiler's job.

teqControl runs the unit, and Carel BOSS 5G monitoring connects it to us over 5G or Ethernet. Operating data reaches us in real time, so a drifting COP gets caught before it becomes a service call.

Aqua runs on CO₂, a natural refrigerant with a GWP of 1, non-flammable and free of PFAS and F-gas exposure. It is the world's first high-temperature CO₂ heat pump certified under EcoDesign, with an Environmental Product Declaration to ISO 14025 and EN 15804, verified by Bureau Veritas. The plant stays legal well beyond the 2027 to 2030 phase-out of synthetic refrigerants.

Aqua is the first model on a modular system built to grow. The roadmap includes an air-to-water heat pump series, an extended brine and water range up to 1 MW, and a Heat-as-a-Service model under evaluation. The platform is built to take on more of the building's heat load over time, not just the technical room.
