| “深冷”集装箱的开发 <正> 美国集装箱服务公司(Container ServicesCo.以下简称CSC公司)和GoReefers国际物流公司达成协议,双方合作共同开发深冷集装箱市场,由CSC负责制造,并使用于欧洲、南美、美国、新西兰、中国和非洲之间的冷冻货航线。新航线将采用CSC公司的“低温动力”(cryo-power)冷藏箱,其主要技术特征是有一套以可循环CO2为致冷剂的低温制冷系统。CSC公司宣称,低温动力为非机械制冷模式,不需额外消耗能源,不增加维护和监控费用。这也就意味着可适用于与标准干货箱相同的任何运输方式,从而降低了运输成本。 | www_xyj | 2011/11/5 |
