NEWS INCORPORATING COLD CHAIN In Memory of Cees Nijssen By John Ackermann and Jan Lievens CEES NIJSSEN 28 SEPTEMBER 1944 – 30 JULY 2020 A TRIBUTE FROM JOHN ACKERMANN After visiting South Africa from his hometown of Leiden in Holland for the first time in June 1998, Cees made many visits to the country to share his experiences and expertise in the post-harvest handling of fruits, vegetables and flowers. Cees followed in the footsteps of his father who started his career as a refrigeration contractor in Holland in 1948. The Netherlands being a major international trading hub for fresh produce, cut flowers and bulbs, there were many that required the committed services of Nijssen Refrigeration. In 1964 Cees joined the family business and soon afterwards the business invested in its own experimental growing rooms to research the impact of light intensity, humidity, soil composition, environmental temperature etc on the growth and quality of products for which they designed cooling systems. Networking with local universities, colleges, nurseries gained Cees wide recognition for his expertise in humidity and temperature control to enhance the quality, appearance and shelf live of fresh produce. On his many visits to South Africa he paid visits to growers and distributions and as a true gentleman shared his expertise and knowledge. After one visit, he even developed, within their experimental tunnel in Holland, a carton that would reduce the cooling time of export table grapes of a South African grower. Cees was clear in his advice based on years of research: start cooling the product as soon as possible after harvest, forced cooling with high humidity air instead of at the lowest temperature and good air circulation through the cartons. With Cees it was not just talk, but action. The Filacell system was one of the products he introduced to prevent the loss of product moisture content during cooling. He often commented that he had seen the best quality of fruit in South African orchards, but that quality needed to be transferred to export markets. He advocated that the quality after weeks of shipping should be the same as that in the orchard or vineyard or nursery. Cees was a true gentleman and always presented himself well and was easy to talk to. His sudden, but very peaceful death, was received with much sadness. May he rest in peace and we salute him as a honoured icon in the extensive field of post-harvest cooling and technology. John Ackermann A TRIBUTE FROM JAN LIEVENS For many years after his last visit to South Africa, Cees remained in close contact with Jan Lievens. By coincidence and through a senior manager of Trust Bank, we met in 1998. Cees developed the Filacell and this concept is to-date, still one of the most revolutionary energy efficient cooling systems for the precooling of fruit, vegetables, and flowers. Nobody up to now can cool for an hour using energy for only 20 minutes. From that moment on, he introduced me John Ackermann Cees Nijssen during a visit to Cape Town on 31 August 1999. to the finer details of what postharvest treatment really means and made me realise that the value for the grower lies in applying the correct technology with the correct timing. From that moment on, Cees ignited my postharvest technology fire and I went on doing what I am doing in becoming a specialist in this field with an esteemed, information-sharing mentor. Cees was and will always be unique. More than 34 years ago, in 1986, he patented as the first Dutch supplier, LED plant growing lights. In joint research with the University of Wageningen he explored the potential of LED lights for plant growth. He sold the ‘Nijssen Light Division’ to a renowned worldwide lighting manufacturer and Nijssen concentrated on developing cutting edge climate rooms. I still remember vividly that the daughter of one of the farmers who had invested in a Filacell at the time, had a school project to grow a vine. Cees gave her one of his patented LED lights and said: “You put your vine under that lamp and look after it and just watch what it will do to the growth.” Her plant outshone every other plant in the school. He came various times to South Africa to give seminars, as he believed in sharing information to the benefit of the industry was the only way forward. Most South African refrigeration engineers came to the seminars to hear what he had to say. Some of them are not here anymore or are not active, but some of them still are and will no doubt remember Cees. The continuous drive for innovation led to the phenomenal growth of his company in various specialised fields. Besides that, he was also of enormous importance to the industry and the local Dutch industry bodies. He was the first to stress the importance on getting a specialised technical education academy going to train young professionals in the refrigeration industry. During one of our last cross-continent conversations, Cees expressed his concern that there is still a huge shortage of qualified technicians. Cees, I will never forget you and I will try to continue the incredible work you did for the industry. Even in our last conversation, you again reminded me to continue with your work. Maybe he had a premonition that his time left was short. Our sincere condolences go out to his wife, Trix, his three children and grandchildren. Rest in peace my friend. CLA Jan Lievens Tragic loss of an icon: Wayne Giles Refrigeration The tragic death of Wayne (57) and his wife Janique Giles (56) at their home in Elandsfontein in the early hours of Monday 3 August 2020, shocked the industry to the core. Wayne Giles Refrigeration is a highlyrespected contractor and the sudden death of Wayne is a great loss. As an industry, we mourn the heavy loss of a gentleman and his caring wife. CLA 8 Our sincere condolences to the Giles family for their loss. Creative Commons www.coldlinkafrica.co.za COLD LINK AFRICA • October 2020
