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
Details
  • 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
