Panasonic has unveiled plans to introduce a highly efficient CO2 condensing unit to the European market. The OCU-CR200VLF unit has been successfully deployed throughout Japan and proved to be 30% more energy efficient than a R404A system.

Panasonic plans to introduce a small single 2HP (horse powers) CO2 outdoor condensing unit (OCU) to the European market. The new OCU was installed and tested in more than 50 convenience stores in Japan with results indicating annual energy savings of 30% compared to a conventional R404A single speed system.

The low temperature OCU with a nominal output of 1.5kW uses a two-stage rotary CO2 compressor and split cycle technology with split internal heat exchanger and intercooler. The outdoor unit is suitable particularly for convenience stores but can also be used with walk-in coolers and other products.

The unit is now mass-produced for the Japanese market. For the European market a voltage reducer is needed until a planned 1-phase 230V model is available. The future plan of Panasonic is to develop a multi temperature unit for freezer and refrigerator applications.

R744 Outdoor Condensing Unit specification:
  • Model: OCU-CR200VLF
  • Nominal output: 1.5kW

About Panasonic

In 2010, Panasonic acquired Sanyo Electric and since then has continued building on Sanyo's expertise in CO2 refrigeration and heat pump technology. The former Sanyo had developed the world's first CO2 rotary 2-stage compression compressor.
