Rivacold has developed ADAPTIX, a control and component package for transcritical CO2 refrigeration systems that adjusts operation to ambient conditions and cooling demand. The company reports initial net energy savings of 18–22% in a 32 kW medium-temperature supermarket installation in central Italy, while larger savings figures are manufacturer claims and have not been independently verified in the source report.
Rivacold has developed ADAPTIX, a technology designed to improve the efficiency of transcritical CO2 refrigeration systems by adapting operating settings to outdoor conditions and cooling demand. The manufacturer reports initial net energy savings of 18–22% in a supermarket installation in central Italy, although the available report does not provide independent verification or full test results.
ADAPTIX combines mechanical components, sensors and Rivacold’s electronic controls and algorithms. The system includes a high-efficiency heat exchanger, a precision three-way regulating valve, temperature and pressure sensors, and the company’s RIV-EVO control board. It is intended to adjust operating parameters as conditions change, rather than rely on a fixed setting.
Rivacold says the technology works on both the gas-cooler discharge side and the evaporator side. It is designed to lower CO2 temperature at the gas-cooler outlet, reduce discharge pressure and limit flash gas. At the evaporator, it aims to raise evaporation temperature and pressure, lowering the compressor’s compression ratio and the power needed to deliver cooling.
The company says the system can also support very low superheat, which may reduce ice formation and the need for defrost cycles. Rivacold reports energy savings of up to 30% when ADAPTIX is used alone and up to 40% when combined with other energy-saving technologies. Those figures are manufacturer claims; the supplied report does not specify the conditions or comparison baseline behind them.
Potential Savings in Store Refrigeration
Refrigeration is a substantial, ongoing energy demand for supermarkets, so changes that reduce compressor power can affect operating costs and the energy use of a store. ADAPTIX is aimed at improving performance across different seasons and cooling loads, including high ambient temperatures and periods of peak demand, rather than addressing only one operating condition.
The reported 18–22% field-test saving gives retailers and system designers an early indication of possible performance in an operating store. It is not yet enough to establish typical savings across other sites: the result comes from one reported installation, and the report does not detail the test’s weather, store load, measurement method or uncertainty. Any investment decision would need to account for site conditions, equipment configuration and verified energy data.
If the reported control approach performs as intended, its ability to work alongside parallel compression, ejectors or two-stage systems could make it relevant to facilities already using, or considering, those efficiency measures. Rivacold says ADAPTIX can operate alone or in combination with such technologies, but the report gives no comparative results for those configurations.

How the Italian Trial Was Run
The field installation is a Rivacold TX system at a supermarket in central Italy. The report identifies it as a 32 kW medium-temperature system that has operated since June 2026. Testing used alternating 24-hour periods with ADAPTIX switched on and off, and Rivacold says initial data showed net energy savings of 18–22%.
ADAPTIX is offered as an optional feature for selected Rivacold R744 condensing units and compressor racks. Availability depends on product configuration and installation requirements. The company says retrofitting may be possible after an assessment of the complete refrigeration system; the report does not say that every existing system can be adapted.

Limits of the Reported Test Data
The available report does not include an independent evaluation, raw energy readings or details on how the comparison controlled for changes in weather, store demand and other operating conditions. It also does not state how long the full test ran beyond describing alternating 24-hour on/off periods, or whether savings were measured across different seasons.
The manufacturer’s claims of up to 30% and 40% savings are presented without a comparison baseline or detailed test conditions. The extent to which those figures apply to other stores, system sizes or combinations with other technologies is not established in the report. Product compatibility and the feasibility of retrofits also depend on the specific installation.

More Site Data Needed
The next useful evidence would be longer-term results from the Italian supermarket, including the test duration, measurement method, ambient conditions and energy use with and without ADAPTIX. Results from additional installations would help show whether the reported savings carry over to different climates, store loads and equipment configurations.
Rivacold lists ADAPTIX as an optional feature for selected equipment, with configuration and installation requirements affecting availability. Customers considering the system or a retrofit would need a site-specific assessment. The supplied report does not identify a broader rollout schedule, pricing or an independent testing plan.

Key Questions
What is ADAPTIX?
ADAPTIX is Rivacold technology for transcritical CO2 refrigeration systems. It uses mechanical components, sensors and electronic controls to adjust system operation to ambient conditions and cooling demand.
What energy savings have been reported?
Rivacold reports initial net savings of 18–22% in one supermarket installation. The company also claims potential savings of up to 30% on its own and up to 40% combined with other technologies; the report does not provide independent verification or detailed baselines for those figures.
Where was ADAPTIX tested?
The reported trial was at a supermarket in central Italy, on a 32 kW medium-temperature Rivacold TX system. The system has operated since June 2026, with testing described as alternating 24-hour periods with the technology on and off.
Can ADAPTIX be added to an existing refrigeration system?
Rivacold says retrofitting may be possible after an assessment of the complete system. Compatibility is not guaranteed and depends on the installation and equipment configuration.
Have the savings been independently confirmed?
The supplied report does not cite an independent assessment. It presents the field result and potential savings as figures reported by Rivacold; more test details and results from other sites are not provided.
