Alfa Laval’s Carnie Marsh highlights the advantages and disadvantages of cascade CO₂/ammonia refrigeration systems, which represent practical alternatives to conventional two-stage ammonia systems for the lower temperature spectrum. Marsh presents Alfa Laval’s semi-welded plate heat exchanger & UTurn(p)TM separator system, developed in order to increase reliability, reduce refrigerant charge and go beyond the conventional gravity separator to a separation by centrifugal forces. He finishes by highlighting the system’s advantages in terms of ammonia charge.
