Conversion of Supermarket Refrigeration System from F-Gases to Natural Refrigerants

Currently, all supermarket refrigeration systems in Southern Africa operate on fluorinated refrigerants with high ozone-depleting and/or global warming potentials. Modern, environmentally friendlier technology based on natural refrigerants is still completely unknown there and is seen with some concern. Most equipment owners, refrigeration engineers and service technicians have been reluctant to discuss these technologies due to potential safety issues.
