The 100th transcritical system planned by Frigo-Consulting has been put into operation in a Coop supermarket in Switzerland. The expert for sustainable engineering can look back on over 10 years of experience with CO2 as a refrigerant and confirms a much higher acceptance from suppliers and end-users due to improved technology, availability and efficiency that saves costs for all parties involved.
Recently re-opened, the Coop store in Basel, Switzerland integrates now the latest technologies including a CO2 booster system specified by Frigo-Consulting Ltd. Besides the advantages of combining efficiently low and medium temperature cooling, the waste heat from the transcritical system is used for the warm water supply and also for heating the store.
It is already the 100th transcritical system planned by the Swiss-based engineering company Frigo-Consulting Ltd. and supports the efforts of Coop to become CO2 neutral by 2023. To achieve this goal, the Swiss cooperative Coop representing one of the largest supermarket chain in Switzerland, is using CO2 booster systems as standards for their new and rebuilt stores.
From subcritical to transcritical adsorption technology
Starting with subcritical CO2 systems in 2003, Frigo-Consulting Ltd. has broadened their experience and technical know-how to transcritical CO2 systems. The first one for medium temperature and a 2-stage low temperature cooling was planned and installed in 2006 and quickly evolved to a transcritical system with parallel compression in 2008. This was followed by the world’s first transcritical system with an integrated expansion machine two years later. Continuously improving and innovating, Frigo-Consulting Ltd. planned also the world’s first transcritical system with integrated adsorption technology for cooling and waste heat recovery in 2011.
The diagram below is showing the most commonly used CO2 booster system with direct expansion. It combines medium and low-temperature cooling:

Reduced life cycle costs when using CO2 convinces the users
With the 100th transcritical system now in operation, the pioneer for CO2 commercial and industrial refrigeration is proving that CO2 systems are running reliably and efficiently in greater quantities. The company also confirms that suppliers as well as end-users indeed recognise the technology due to better availability of components and systems and proven efficiency and cost-reductions, including more concretely:

- Low life-cycle costs: reduced investment and operating costs, no cost risk for possible refrigerant shortage or taxes, higher temperatures for waste heat recovery
- High security: neither toxic nor flammable, no secondary loops required
- Environmentally friendly
