Many manufacturers are installing dual refrigerant charging systems in preparation for the EPA's phase-out of R-22. What other strategies are being used in the industry?
More than one refrigerant per station. They are using charging stations that can deliver R-22 for one unit, and then R-410A for the next unit. This enables them to use up their supplies of R-22, while ramping up alternative refrigerant usage at the same time. By using one charging station for both refrigerants they save space and are able to respond in real-time to market demand. Here's an example of a dual charge unit :
