FlexiCO2OL®

Multiple Compressor Rack
R134a/CO₂ Cascade
Medium and Low Temperature Separate Frames

BENEFITS AT A GLANCE

  • High-technology level with intelligent hybrid connection through cascade sequence
  • Best reliability with an oil distribution system without moving parts
  • Ability to service from front and side only, thus allowing to save machinery room space
  • Fast installation by prepared CO₂ receiver and heat exchanger in the rack

APPLICATIONS

  • High capacity solution for large supermarkets and hypermarkets
  • Indoor installation with enhanced flexibility and customization ability

  • REFRIGERANT:

    R134a (MT),

    R744 (CO2) (LT)

  • COOLING CAPACITY:

    up to 278 kW (MT),

    up to 75 kW (LT)

FlexiCO₂OL® combines a natural refrigerant and the lower GWP for HFC solution, with subcritical CO₂ for low-temperature application (LT) and R134a for medium-temperature application (MT).

Key Features

  • Ecological system with one MT cycle HFC R134a and one LT cycle CO₂
  • Powerful separate racks designed to operate for each refrigeration cycle
  • 3- to 6-stage semi-hermetic motor compressors for the MT refrigeration range (Bitzer - Ecoline series) with the refrigerant R134a
  • 2- to 4-stage semi-hermetic motor compressors for the LT refrigeration range with the refrigerant CO₂
  • Compressor protection with Thermistor
  • Motor compressor with suction and pressure stop valve and oil sight glass
  • Oil differential pressure switch for motor compressors of the series BE5 and BE6
  • Multicompressor system control panel to locate sensors, pressure switches or similar as requested
  • Built-in receiver for the CO₂ circuit (dependent on the compressors)
  • Cascade heat exchanger (1 or 2 piece) adapted to the CO₂ condensation capacity
  • Electronic expansion valves for cascade heat exchanger (LT)
  • System frame
  • Assembled control box available

Options

  • Energy-saving package by frequencies controlled LT and MT compressors
  • Optimized reliability with the base load shifting of frequencies controlled compressors
  • Separate receiver with various sizes and equipment available
