Daikin Reefer has unveiled new container refrigeration technology that is said to meet carrier and shipper demands for low energy consumption and greenhouse gas emissions, while providing precise cooling performance for chilled and frozen cargoes.

The new LX10F container refrigeration unit, to be marketed under the brand name ZESTIATM, uses Daikin’s patented DC inverter scroll compressor technology to deliver large energy savings of approximately 45% compared with existing designs on the market today, says Daikin.
The company says that traditional single speed compressors can only deliver a fixed amount of cooling and heat and have to operate on a ‘stop-start’ principle to maintain a set temperature. By contrast, inverter compressors run at variable speeds, allowing cooling capacity to be adjusted according to cargo needs, ambient conditions and how the refrigeration unit is being used. This provides a more flexible, energy-efficient and accurate way of dealing with the extremes of perishable cargo transport.
A key component of Daikin’s DC inverter technology is the Daikin Reluctance DC motor, a patented design that uses a strong neodymium permanent magnet for improved efficiency at all rotational speeds. Operating at high torque and efficiency without slip, the Daikin Reluctance DC motor further reduces power consumption.
ZESTIAis a unit that will be particularly suited for international operators requiring the highest levels of cooling performance, temperature precision and low energy consumption, says Daikin.
Along with the new DC-inverter technology, ZESTIA incorporates a number of advanced control features to further improve ease of operation, maintenance and troubleshooting. The unit’s microprocessor controller has been significantly enhanced, with user-friendly large, backlit LCD screen to give a clear view of temperature records even in dark conditions, including new graphical data display.
Authorised users can also now download trip data and upload software by using a USB memory stick in around 30 seconds, rather than needing to plug in a laptop into the controller. Also new is the use of LED indicator lights on the controller, helping users to identify failed parts and avoid misdiagnosis of faults.
“Daikin is excited to bring its proven DC inverter technology to the global refrigerated container market,” said Shin Furuta, President, Daikin reefer business. “After more than two years of research and development, we are confident that ZESTIA will meet the industry’s needs both today and for the foreseeable future.”
