The system overall, “is a cost-effective solution for intermediate-size plants that are too small for full-scale ammonia, and too large for Freon,” Hajjar argues.
“It’s an appropriate trade-off between efficiency and cost whilst remaining natural refrigerant-based. It eliminates ammonia from the field, can be scaled up or down, and is entirely appropriate for supermarket applications,” he asserts.
Using a CO2 rack with only minimal additional features helps to improve the cost effectiveness of the Fung Lea system still further.
