PROJECT INCORPORATING COLD CHAIN be piped to ice makers, evaporators in cold stores, blast freezers, or plate freezers. The packs are complete with control panel and require the least amount of site wiring. A very distinct advantage of the packs is flexibility and Gansbaai Marine is a typical example. Previously, if something went wrong with the system, the entire plant would shut down and the operation would stand still. Now, because the four packs are independent systems, if one shuts down, the rest can still operate as normal, preventing any loss of production. The Everflo package design also negates the need for ammonia pumps, simplifying the system design to make things easier for the client. It is a stop-and- start operation without all the unnecessary complex functions. It also requires a much lower ammonia charge than a central The four flake ice makers have a combined output of 100 tonnes of flake ice per 24 hours. plant and much shorter pipe runs — all adding up to great cost savings and easier of the client and the engineering side the ammonia freezing package, and the demands of the marine industry, the of things.
