Why CO2?: Natural refrigerant.
EU F-Gas Regulation is a key priority for European countries. It ensures compliance with the Kigali Amendment supporting international climate commitments on greenhouse gases and leading the global transition to climate-friendly HFC-free technologies.
Carbon dioxide (R–744) is regaining its place in the refrigeration world. Driven by environmental concerns, legislation is requiring increased adoption of ‘alternative’ refrigerants, of which CO2 is one.
CO2 is a very attractive refrigerant from an environmental perspective. Zero ODP and “GWP” (Global Warming Potential)=1 means natural substance in the atmosphere.
In Europe a step-by-step HFC reduction has been in place since the F Gas regulation was introduced in 2015.
In fact, not only in Europe but also other countries all over the world have actively been preparing to enact the necessary domestic legislation to implement the agreement for reducing the use of HFCs.
Panasonic is now able to provide a solution in Europe with CO2 refrigeration systems to prevent global warming and to support environment-friendly retail operations.
The following table shows how well R744 (CO2) performs regarding environmental impact and safety.

ODP (Ozone Depletion Potential) = 0 - GWP (Global Warming Potential) = 1.

CO2 transcritical condensing units New MT/LT model (OCU-CR1000VF8A(SL))
Panasonic has introduced new model offering both MT and LT options. An enlarged 12L tank in this new model ensures an optimum operation.

Both MT and LT options.
Maximum cooling capacity. MT: Up to 16kW. LT: Up to 8kW.

Up scales tank 7L to 12L.
This 12L tank keeps inside extra amount of refrigerant when the system stops. Also helping installers by making wider tolerance from optimum charge.
Heat recovery function for heating. Available in Autumn 2019.
This function offers refrigeration together with heating in one system. Its a ground breaking function giving a great opportunity to cut running costs by utilizing exhausted heat from refrigeration to the energy source for heating.

What is Heat Recovery function?
Before.
Eg. CO2 condensing system for refrigeration + A2W system for heating.
New solution.
Heat Recovery system can produce not only refrigeration but also heating by heat recovery.

Reliability is our main target and therefore we offer compressor warranties of 5 years, and 2 year warranties on other components!



Superior cooling capacity at each evaporating temperature.
CO2 Transcritical Condensing units have a high cooling capacity at each set point. CO2 2-stage compression rotary compressor developed by Panasonic is designed to compress CO2 refrigerant twice; it reduces load in operation by half compared with 1-stage refrigerant compression and delivers better durability and reliability.
Units can be set to run at low and medium temperatures with four initial settings. These settings can then be modified by turning a simple and user friendly rotary switch to further enhance energy savings. (200VF5 model only).
4kW: OCU-CR200VF5(SL)
This compact unit provides flexibility to adapt to changing needs of refrigeration depending on the install setting.

Panasonic condensing units with natural refrigerant: The environmentally friendly and reliable solution for convenience stores, supermarket, gas stations and cold rooms.



Cold chain applications.
Panasonic’s CR Series of C02 condensing units provide the ideal solution for supermarkets, convenience stores and gas stations.
Keeping food always fresh at right temperature in showcases or cold rooms is a very critical point. And one of the biggest challenges for those retailers has been the expensive effects of refrigeration breakdowns which can result in costly product wastage.
Panasonic’s reliable CO2 solution helps address the above issue by having a stable and reliable all year-round system to help maximise energy efficiency.
