CompactCO2OL®
CompactCO2OL®
Multiple Compressor Rack
R134a/ CO₂ Cascade
Medium and Low Temperature
BENEFITS AT A GLANCE
- High-technology level with intelligent hybrid connection through cascade sequence
- Reduced footprint with a single frame combining the MT section the LT section and the cascade heat exchanger
- Energy saving due to our energy-efficient semi hermetic motor compressors
- Safety operation with redundant components and several safety devices
APPLICATIONS
- Cost-effective solution for supermarkets and discounters
- Indoor installation
-
REFRIGERANT:
R134a (MT),
R744 CO2 (LT)
-
COOLING CAPACITY:
up to 197 kW (MT),
up to 75 kW (LT)
CompactCO₂OL® 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
- More than 110 different standardized models for various applications available
- Control panel with Carrier controller, especially developed for R134a/CO₂ operation
- 2- to 4-stage semi-hermetic motor compressors for the MT refrigeration range (Bitzer - Ecoline series) with the refrigerant R134a
- 1- to 3-stage semi-hermetic motor compressors for the LT refrigeration range with the refrigerant CO₂
- Motor compressor with suction and pressure stop valve and oil sight glass
- Compressor protection with Thermistor
- 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 to 2 pcs) adapted to the CO₂ condensation capacity
- Electronic expansion valves for cascade heat exchanger
- Attached (bypack): two-way valve with 2 safety valves 45 bar for connection to the LT receiver
- Attached (bypack): two-way valve with 2 safety valves 25 bar for connection to the LT suction line
- 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
- Heat reclaim system for energy reduction
- Separate receiver with various sizes and equipment available
