No more rivets Improved door design provides increased water tightness and durability while simplifying repairs Reefer doors are exposed to impacts during loading and unloading. This is why door repairs are a relatively common occurrence among the global reefer fleet. In response to this situation, MCI has implemented a new patented door design that will prevent some of these repair costs in the future. No rivets – no water ingress The most visible improvement is that rivets have now been fully eliminated, thanks to the new design of the PVC door frame. The absence of rivets means that there are no holes in the gasket or the door frame and thus no gaps directly into the insulation foam. This results in a remarkable improvement in water tightness. Rivets are generally the weakest point on reefer doors when it comes to preventing water ingress into the insulation foam. The inner door frame is improved by using reinforced flexible PVC to minimise impact. New patented door design on Mark Q: The contact point between the door side and the PVC door frame has also been redesigned to create a labyrinth seal, which makes it even harder for water to penetrate the lining. These new features minimise the risk that insulation properties in the reefer doors are compromised by water ingress. Stronger inner frame Repair statistics show the inner side of the door frame to be prone to impact from forklift arms during loading and unloading of cargo. To minimise this, the material of the inner door frame has been improved as well. On the new door design, the inner door frame is moulded from reinforced PVC, which is softer and more flexible than traditional PVC. This enables the new inner door frame to absorb impacts and bumps that would otherwise cause damage. In common with the rest of the PVC frame, the new inner door frame is also thicker and sturdier. The new door frame consists of just three parts, making a reefer less complex to repair in the event of damage. All in all, the improvements should lower maintenance costs in the future. Improved labyrinth seal The improved door frame No more holes for rivets in the door frame and gasket Star Cool development team strengthened Ole Thøgersen has taken up the role of refrigeration engineer. He comes from a position as lead engineer and has been working with reefer unit technology for 17 years. Ole Thøgersens brings to MCI his great experience and knowledge about the industry and customers needs. He will be working on development and system control of the Star Cool unit. Torkild Folmer Pedersen has taken up the position of technical specification specialist. He has many years of experience with electronics and is already familiar with parts of the Star Cool unit. His main working areas will be to maintain and optimise the functional specification of the SC controller software, and to perform operational development and software testing.
