Cannon's refrigeration technology wins repeat orders

Maersk makes reefers in Chile Maersk Container Industry (MCI), a business unit in the A. P. Moller - Maersk Group, has again selected Cannon for the supply of a complete foaming plant for the production of its reefers. These temperature-controlled containers are used to transport frozen or refrigerated goods. In the 1990s Cannon had supplied a production unit to Maersk's factory in Tinglev, Denmark. The new equipment will be installed in the new MCI factory in San Antonio, Chile. This will be the first reefer manufacturing facility in some time to be located outside of China and the first in Latin America. Previously, Maersk had relocated all of its reefer manufacturing capacity to China, where MCI operates a plant in Qingdao. San Antonio is ideally located being the largest reefer exporting region in Chile and also within close proximity to the other busiest container terminal, Valparaìso Port. Scheduled to open at the beginning of 2014, the new plant will have an annual capacity of 40,000 x 40 ft cube reefers as well as a number of Star Cool reefer machines. It will also be able to build 8 ft 6 in high units to cater for the banana trade. The project will require a total investment of USD 170 million and create up to 2,200 new jobs. According to MCI, the new factory will help correct a reefer trade imbalance that disfavours exporters of fresh produce, fish and meat from western South America. "The new factory will produce Maersk's high-tech reefers in a part of the world where exporters have problems gaining access to reefers,” said Peter Nymand, MCI CEO.[image_0] The core of the plant will be the PU injection plant, where all the foam-insulated components of the box reefer - side walls, roof, floor, front, doors, and corners - will be manufactured at a rate of one complete box assembled every 9 min. The PU foaming equipment will cover an area of approximate 4,300 m2. Ten Cannon high-pressure, high-output dosing units will feed, for the foam injection, 25 mixing heads (FPL and JL type) mounted on nine large polymerisation presses, designed according to their well-known "2+2” and "1+1” platens swapping system, for the large and small steel sheet/PU/steel sheet sandwich panels. The presses will be manufactured with a concept that allows for the future implementation of new foaming technologies and of further polymerisation equipment, to enhance the plant volume output and the quality of the foamed panels. "The reasons for choosing Cannon for this major contract were mainly linked with our experience in the field of automated production of extra-large insulated panels and with the capacity of assembling a team of specialists able to provide quick answers and innovative solutions for Maersk' new factory expectations. Cannon will be the single interface for the whole supply, that will be manufactured by several group units: Cannon Afros for the dosing and mixing equipment, Cannon Ergos for the integration of all components, Manni for the polymerisation and material handling elements, Shinnon for the supply of ancillary parts," said Marco Volpato, Managing Director of the Cannon Group. Second VAI plant for Haier, China Cannon has also received another order from China for a mass production PU foaming plant for domestic refrigerators manufactured with its Vacuum Assisted Injection (V.A.I.) technology. Haier, a leading manufacturer in cold appliances, placed its second order for one 16-fixture foaming and polymerisation equipment line for its Qingdao factory. Haier's repeat purchase of a V.A.I. foaming equipment line reinforces the continued commercial success of Dow Pascal technology, first launched to the industry in September 2011. According to Cannon, Haier is convinced of the benefits of the V.A.I. technology in combination with the Dow Pascal raw materials system because of: Increased productivity per foaming station: thanks to the use of highly-reactive formulations that provide a faster demoulding time, a 135 s curing cycle is now the reference for a wall thickness up to 10 cm, using the appropriate PU chemical formulation by Dow for this technology. Optimised distribution of foam throughout the whole cabinet: a uniform density of 33 ± 1 kg/m3 is constantly achieved. Substantial foam savings: up to 5 % are regularly obtained in the first fine-tuned plant.Optimum insulation performances: the foam Lambda value is as low as 18.6 ± 1 mW/m K. The first industrial plant working with the V.A.I. technology, delivered to Haier's Chongqing (China) plant, has been producing the company's Class A refrigerators since 2011. The second plant, destined to the Yellow Island, Qingdao factory, will make the side-by-side wider models. 16 curing jigs, aligned in two eight-fixture rows, will once again be supplied to Haier in Qingdao, providing an output capacity of four foamed cabinets per minute. Two A-System metering units connected to four SR24 mixing heads will precisely feed the amount of foam required by each cabinet. A centralised vacuum station will provide in each mould the negative pressure required at a very constant level for the whole period of the chemicals' injection and of the foam's expansion. The delivery and start-up of the new plant is expected by the second half of 2013.
