MaxiCO2OL®

Efficient, natural refrigeration

The Carrier MaxiCO₂OL® range of refrigeration racks utilize natural refrigerant carbon dioxide (CO₂) to provide sustainable, energy-efficient refrigeration solutions across a wide range of cooling capacities.

MaxiCO₂OL racks form part of the Carrier CO₂OLtec® range of CO₂ refrigeration plant. CO₂OLtec systems demonstrate average energy savings of approximately 10 percent compared with traditional HFC refrigeration systems in mild to cold climates, resulting in attractive life-cycle costs and low return on investment periods.

CO₂ is a climate neutral refrigerant; it has a Global Warming Potential (GWP) of just one and an Ozone Depletion Potential (ODP) of zero and is not subject to the EU F-Gas Regulation.

Key Features

• 3 to 6 medium temperature (MT) compressors
• 3 to 4 low temperature (LT) compressors located on a separate LT booster frame
• Variable Speed Drive (VSD) for primary MT compressor
• Maximum allowable pressure levels as detailed below (alternatives available):
  • LT suction = 25 bar
  • MT suction/common liquid = 45 bar
  • Discharge/gas cooler return = 120 bar
• Integrated electrical panel incorporating rack and gas cooler controls
• Eckelmann controls as standard, with option for either Danfoss or Wurm
• Specially designed service modules allow all maintenance activities to be carried out from the front and one side, thus saving plant room space
• Standardized, factory produced units

Options
