New CO2 testing and analysis service

Through working in partnership with Sainsbury’s, A-Gas has introduced a new carbon dioxide (R744/CO2) analysis and testing service in a move to improve the monitoring of CO2 refrigeration system performance. Ensuring moisture content and other impurities are kept within the recommended levels should be a key focus for everyone involved in the CO2 supply chain in the food production and supermarket industries.

A-Gas Managing Director John Ormerod said: “Natural refrigerants like CO2 are no different to traditional HFCs when it comes to quality. Ensuring CO2 supermarket systems operate within the strict boundaries of the correct moisture specification improves efficiency, reduces maintenance costs and saves money. During conversations with Sainsbury’s refrigeration technical specialist earlier this year, Sainsbury’s requested A-Gas’ expertise to help deliver a solution that would enable the monitoring of the quality of CO2 in their refrigeration systems and thus ensure reliability is maintained.”

Following successful tests with Sainsbury’s, A-Gas has now extended this analysis service to the rest of the HVAC industry. A-Gas provide customers with a suitably-rated cylinder in which they can supply a liquid sample from the refrigeration system. This is returned to A-Gas where it is tested in their state of the art laboratory and a full quantitative assessment is made.

Sainsbury’s Head of Refrigeration John Skelton said: “This service enables Sainsbury’s to monitor that the quality of the refrigerant within our refrigeration systems is within the manufacturer’s specification ensuring the reliability and longevity of all components.”

Earlier this year, A-Gas launched a new high specification Carbon Dioxide (R744) refrigerant, eCO2. The refrigerant is produced sustainably from waste sugar beet, is UK-sourced, has excellent thermodynamic properties and is a green alternative to HFC gases like R404A, commonly used in these industries. With a moisture content of 5PPM, A-Gas’ eCO2 sets the CO2 standard for the future and is the driest CO2 available in today’s market.
