PAM Refrigeration, the South African manufacturer of flow-ice systems, has received an order for a pre-packaged flow-ice machine for a Tasmanian salmon farm.

The local contractor is Degrees C, located in Devenport and PAM designed and manufactured the system delivered by Flow-Ice Australia (Pty) Ltd.

The project required a high concentration of 40% slurry ice to be delivered to tanker trucks for transporting salmon to the processing factory. The sea water salinity drops during the rain season and PAM had to consider low saline conditions in the system design.

The local contractor supplied a 50m3 tank and PAM supplied all the controls and agitator for the ice handling and delivery to the tanker trucks.

The system capacity is 3,000l per hour at 30% ice concentration with sea water temperatures of 20oC.

The refrigeration capacity is 165kW with ammonia as refrigerant. The system design is very robust and industrial and the power consumption of the compressor is only 40kW. PAM tells World Fishing & Aquaculture that its system design is one of the most efficient methods of ice production.

The system was designed to fit into a 6m container for transport and will be transferred to a 12m container on site, where the balance of the space will be used for ice handling and other controls fitted for the operation. PAM says that the advantage is the small footprint of the total system delivered as a complete packaged unit.

PAM has more than 15 years experience in manufacturing flow-ice systems. The company’s flow-ice generators are manufactured according the CE certification and pressure vessels on the system can be made according to any international standard required.
