Metraclark, Highveld refrigeration, Recam and ZZ2 farms set out to design the new additional cold storage facility for ZZ2 at their Elandsdrift facility. This facility is specifically aimed at cold storage and ripening of avocados.
The system design for phase 1 and phase 2 called for a plant capacity of 400kw @ -4°C suction on R507 refrigerant. Janine Buitendag the engineer responsible for the project, worked tirelessly to ensure all the requirements to make this project a successful one were met.
The order was received at the end of October 2014 and Metraclark and Recam received strict instructions from the contractor that the units had to be delivered before factory shut down over the December period. This only left Recam a time frame of six weeks to build and deliver the biggest outdoor weatherproof multiplex they had ever done. Recam delivered under extreme pressure! This included the wiring of the electrical boards according to the specification set out by the American consultant.
This is the first of its kind in the country using this type of specified ripening room, merging equipment from local suppliers and evaporators developed and imported from the USA. These evaporators are specially designed to control temperature in individual racks or sections of avocados as required in the ripening process. These specialized evaporators of 42kw each are connected to the Recam multiplex system. The ripening rooms are temperature and humidity controlled.
South African consumers will benefit with the availability of ripened avocado in the market year round.
