Refrigeration units - CO2

CO2 cooling units

Transcritical aggregates with factor CO₂ – CR series

With the expansion of the CR series with new MT/LT 4 HP models, users can choose from a wide range of refrigeration systems that meet the specific needs of small retail stores.

Why CO₂? Natural refrigerant

The EU F-gas regulation is a key priority for European countries. The regulation ensures compliance with the Kigali Amendment, which confirms the international community's climate commitments on greenhouse gases and aims to achieve a global transition to climate-friendly technologies without hydrofluorocarbons (HFCs).

Carbon dioxide (R744) is regaining its place in refrigeration.

In connection with environmental concerns, new regulations introduce the obligation to increase the use of "alternative" refrigerants, such as CO2. It is an environmentally friendly substance and occurs naturally in the atmosphere, which confirms zero ozone depletion potential (ODP) and global warming potential (GWP) = 1.

Since the introduction of the F-gas regulation in 2015, European companies have been gradually moving away from the use of HFCs.

Other countries around the world are also actively preparing to adopt the necessary regulations to implement the agreement on the restriction of the use of HFCs. Panasonic is currently introducing CO2 refrigeration systems to the European market, which will help prevent global warming and reduce the carbon footprint of retail outlets.

The table below shows the very favorable parameters of R744 (CO2) in terms of environmental impact and safety.

Highest cooling capacity at any evaporation temperature

Transcritical CO2 units deliver high cooling capacity at any setting. Panasonic’s two-stage CO2 compressor compresses the refrigerant twice; compared to a single-stage compressor, this reduces the operating load by half, providing greater durability and reliability. The units can be configured for low to medium temperature operation. These settings can then be modified using a simple, user-friendly rotary switch – to further enhance energy savings.
