FlexiCO2OL®
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
