A-Gas sets the CO2 standard for the future
A-GAS HAS LAUNCHED a new high specification carbon dioxide (R744) refrigerant. Known as ‘eCO2’ due to its environmental credentials, it is produced sustainably from waste sugar beet, is UK-sourced, has excellent thermodynamic properties and sets the standard for those looking for a green alternative to HFC gases like R22, commonly used in these industries.
The cooling industry has known for several years that R22 is being phased out but under recent amendments to the F-Gas Regulations, HFC refrigerants with a Global-Warming Potential (GWP) of 2500 are on a cap and phase down, with future supply being restricted. Many retrofit refrigerants also fail the F-Gas test, so eCO2 from A-Gas provides a cutting-edge alternative for those looking for a sustainable option. A-Gas operations manager Rob Parker said: “The X Factor for eCO2 is the sustainable
way it’s produced. Most CO2 refrigerants are recovered from dirty industrial processes which are far from green in their methods. eCO2 is a by-product of bioethanol production from waste sugar beet – using crops not destined for sugar production. This is a first for A-Gas and the UK market, as a
CO2 refrigerant produced from waste sugar beet has never been on sale before on a commercial basis.
“eCO2 can be used in a range of applications but it is particularly suitable for supermarket refrigerant systems, as its green credentials give it stand out qualities in an

industry where reducing the carbon footprint is high on the list of priorities.”
Like traditional refrigerant
grade CO2, eCO2 has a low environmental impact with zero ozone depletion potential and a global warming potential of one. However, with its ultra-low moisture content, eCO2 is certified to exceed refrigeration grade specification – giving it the edge over lower grade carbon dioxide. Low moisture content and high purity enable the refrigerant to work more reliably, which in turn extends the life of equipment. eCO2 is recovered from the natural fermentation of the sugar beet crop. Bioethanol production is a highly integrated and sustainable local operation with the sugar beet crop sourced close to the factory.
The waste beet does not compete with other food sources and, as part of the process, raw carbon dioxide
is recovered, so no new CO2 enters the atmosphere. Rob Parker added:
“Increasingly, supermarket chains are thinking of switching to greener refrigerants because they are aware of the phase- out of R22 and the changes under the F-Gas regulations. eCO2 is an attractive option for those who want to keep pace with these developments by choosing the first sustainably
produced CO2 refrigerant.” eCO2 is available from A-Gas wholesale partners in a range of portable cylinders for standard use and Manifold Packs and Dewar cylinders for larger installations.

Airflow’s new family of industrial fans
A NEW ‘FAMILY’ of EC centrifugal industrial fans has been developed by Airflow to carry on its heritage of air movement solutions. The upcoming changes to minimum efficiency regulation rates of ErP 327/2011-2015 mean that commercial fans in the EU marketplace will soon require a much higher minimum efficiency if the input power is between 125W and 500kW. In response to the changes, Airflow has launched a range of compact high efficiency driven EC commercial fans that use up to 80% less energy than their AC fan predecessors.
Airflow’s new low energy EC Single inlet fans achieve volume airflow from 83l/s to 115l/s and have significant pressure development on the largest model.
High FMEG levels ensure they are fully compliant with updated regulations. Constructed from mild steel with a robust coating to finish, each fan casing is fitted with an outlet flange, incorporating fixing holes for ease of installation.
Airflow’s larger offering of double inlet high efficiency EC fans are also engineered for significant benefits in performance and pressure, and are specifically designed

for applications where low noise levels and/or space is an issue.
The new range achieves from 165l/s to 1200l/s and over 700 Pascals.
Both single inlet and double inlet offer a good range of control using 0-10V input, due to the high efficiency EC motor, and have a tachometer reading using 0-10v output as well as feature up to IP24 ingress protection.
An auto shut-off and reset function for over/under voltage and temperature on the EC Double Inlet Fans is also a standard feature. These fans have been designed with not only the dimensions and performances of some of Airflows older double inlet range that will become non-compliant in terms of efficiency in 2015 in mind, but more, will also offer a high efficiency EC fan for any new commercial HVAC application.
Bob Sharples, commercial product manager at Airflow Developments said: “In wake of recent changes to energy efficient regulations, here at Airflow we strive to supply to demand, and our extensive range of compliant EC Fans are a first to the EU fan market based on dimension and unique performances.”
