We make it our business to understand the current climate in the shipping markets. The pressure to cut energy usage for environmental and financial benefits is being felt across the global shipping industry. Daikin is commited to helping the shipping industry meet the energy challenge through continuous development of innovative technologies and best practice advice - while never losing sight of the main objective of providing top quality performance.

A simple software installation offers substantial energy-saving benefits for new and existing Daikin reefer units
Daikin Temperature Management System (DTMS) is a software application developed by Daikin for use with both new and existing LXE10E reefer units.
The first version was launched in late 2005, providing reductions of up to 50% power consumption as well as enhanced carriage conditions, including reduced cargo dehydration.
Following additional research and development, the second version of the software, DTMS2, was launched in 2008, providing a further 25% reduction in power consumption.
Machines fitted with the DTMS2software never deviate more than +/-½ deg C from set-point in chilled mode, so there is no compromise to cargo carriage conditions.
DTMS is ‘intelligent’ software that works by automatically adjusting the operation of the reefer unit based on varying ambient conditions (supply air) and cargo respiration rates (return air) while the container is in transit. The continual fine tuning enables temperature and airflow inside the container to be controlled with much greater accuracy than normal, as the system responds to actual conditions.
The real time monitoring and adjustment ensures that the refrigeration unit operates at optimum efficiency, using the minimum amount of power to get the job done.
Daikin was the first reefer machine manufacturer to recognise the benefits of monitoring both supply air and return air temperatures, together with their rate of change, in this way.
Daikin’s dedication to developing software solutions means that performance-enhancing technologies are available to existing as well as new customers.
Daikin LXE 10E machines already out in the field can now be retrofitted with the latest DTMS software to make them as up-to-date as a new machine…without costly hardware modifications. For further information on how to obtain DTMS software for your fleet please contact the relevant sales person covering your region on our contacts page.

Heat-shielding paint to help cut shipping emissions and fuel consumption
Daikin’s Fluoro Chemicals division has developed a special heat-shielding paint that works by reflecting direct sunlight more effectively than ordinary marine paint, thanks to the use of revolutionary infrared reflective paint technology.
Recent trials by Mitsui OSK Lines (MOL) on a large passenger ferry showed a 5.5oC cooling effect from using the paint to cover the deck of the ferry
That translates into an annual reduction of 8.9 tons of CO2 emissions, plus a saving of about 2.2 tons of C oil - just from using heat-shielding paint on 800m2 of deck.
ZeffleTM has several promising applications within the shipping industry, including containers.

- Air vent settings

Simple shipper best practice can reduce emissions and energy consumption.
In the containerised transport of chilled goods, independent industry experts have observed that fresh air vents are often set wider than necessary for the cargo being carried - sometimes by up to 50% more than the produce requires.
A very simple method for making further reductions in CO2 emissions and fuel bills is to ensure that air vents are set to the correct aperture for the produce being transported.
Setting the air vents correctly reduces the amount of fresh air entering the container. This in turn reduces the amount of cooling that the unit has to perform in order to maintain the set-point temperature while still transporting the cargo safely – thus sparing the environment and saving money.
Shipping lines are obliged to transport goods as per the shipper’s instructions. Therefore, shippers have a vital role to play in ensuring that they and their staff are familiar with the correct air vent settings.
Currently, some shippers use “% air vent open” instructions, while others specify requirements in cubic meter per hour (CMH). Since reefer box manufacturers use air vent designs with differing maximum air exchange rates, Daikin recommends CMH as the most accurate instruction method.
