Feature The right training and certification is important to handle all types of works of gases, new and old. Once the recovery is complete, it is important that the waste product is returned to the refrigerant processor in the correct cylinders. Standard HFC’s are sent back in normal recovery cylinders but if the engineer knows in advance that A2Ls are likely to feature they should ensure that they have the right recovery cylinders to handle these gases. If you want to take the stress out of recovery, the A-Gas Rapid Recovery team will do the work for you. Rapid Recovery will take care of it from start to finish – handling all aspects of the job including hazardous waste documentation and job site reporting. It will also be significantly quicker and allows the engineer to get on with other onsite maintenance while the recovery process is taking place. Don’t forget that if you are recovering refrigerant yourself you will need to complete all the necessary hazardous waste paperwork – otherwise, you will have the Environment Agency to answer to. You will need an authorised waste transfer note to transport and remove the waste from the site and when the product is returned in a cylinder to the wholesaler. My advice, if you are unsure is to talk to your refrigerant wholesaler or supplier. They are always happy to help. As an industry we have responded well to the calls to re-use refrigerants. The amount of recovered refrigerant returned to the market is increasing and leakage rates continue to drop. Awareness that recovered product is available on the market www.hvacronline.co.za to use until 2030 is beginning to increase. Investment has been made in A-Gas’ reclamation technology to meet the demand of this reprocessed product. I can reassure you that there’s no need to fear that recovered refrigerants won’t be available. As long as engineers recover gases responsibly – ensuring that we don’t release further emissions into the atmosphere – the greater the amount of refrigerant that will be returned and reprocessed for further use by the industry. Simply introducing systems using new generation refrigerants is not always the answer to the customer’s needs. It makes little sense to destroy usable equipment worth millions of pounds if reclaimed product is there and available to use. Reclaimed refrigerant will continue to play an increasing role as equipment longevity is extended which in turn provides breathing space to the end-user as they assess their options. There is no shelf life to recovered refrigerant. Each molecule can be recovered by the processor to allow the refrigerant to be returned to a pure gas time and time again. Over time new generation refrigerants will slowly drive the phase-out of HFC gases and only then when this is completed will this recovered product be no longer needed. In this respect, the likes of R404A will be around and ready to use in recovered form for many years to come. RACA RACA Journal I May 2020 41
