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
