MAJA RVH-CO2 Flake Ice Machine

Highly sustainable flake ice production

  • Hygiene concept for food-safe flake ice production
  • Compatible with direct carbon dioxide refrigeration systems
  • Natural refrigerant R744 – less environment impact
  • Wide range of customized accessories and options


The flake ice machines MAJA RVH-CO2 without condensing unit are designed for direct carbon dioxide operation with a R744 multicompressor refrigeration unit. For ecological and sustainable ice production projects.

Ice output 500 - 15,200 kg / 24 h

Hygienic, food-safe ice production

MAJA flake ice machines are labeled HY-GEN protected. This stands for excellent sanitary conditions:

  • Easy access to cleaning relevant parts from all sides, without the use of tools.
  • Easily removable, round-shaped plastic water tank.
  • Water tank without built-in parts, angles, edges and screws, allowing easy and thorough cleaning.
  • Automatic water pipe rinsing after 24 hours without ice production.
  • Special hygiene advantages in accordance with the German drinking water regulations.


  • Optimum energy efficiency – increased power density:
    Compared to traditional refrigerants, e.g. R404A, the direct carbon dioxide operation brings more power density, thus increased ice output of up to 30 % compared with the same machine scale.
  • Electronic expansion valve for optimum evaporation efficiency
  • Eco-friendly flake ice production and excellent ecological impact by using the natural refrigerant
  • R744 (carbon dioxide / CO2) for flake ice production: ODP = 0, GWP = 1
  • R744 consists of the elements carbon and oxygen, which are natural parts of the atmosphere.
  • Installation conditions:
    Subcritical R744 circuit HPmax = 90 bar, LPmax = 28 bar; other conditions on demand
  • Evaporation pressure regulator to adapt the evaporation temperature to t0 = approx. -25°C
  • Stop valve liquid line and suction line
  • Pressure relief valve with interchangeable valve for maintenance
  • If necessary, a R744 gas detector can be added to the installation (depending on the local situation at the place of installation).

Easy operation – convenient ice handling

  • Easy operation by Control Panel Touch with timer function for freely programmable production and cleaning cycles (with option MAJA-SCS).
  • Solid machine structure, frame and housing in stainless steel.


Patented fully automatic self-cleaning system:
MAJA-SCS for time savings and optimum hygiene safety by automating the cleaning process.

Ozone degermination system:
Optimal hygiene conditions already in the water inlet.

Hybride solution RVH-CO2 HYBRID:
Ideal for customers who are interested in investing already now in a RVH-CO2 and to operate it with an existing R449A or R404A circuit as an interim solution until final refit of the whole refrigeration system.

Wide range of accessories and options allowing individual machine installation:
Subframes, consoles for wall fixation, chutes, ice level sensors, ice transport and storage solutions, flake ice silos, ice batching solutions.


Preventive maintenance can detect system wear and imminent malfunctions at an early stage. 
By checking and regulating system parameters, the operational reliability of your flake ice machine is increased and energy-efficient operation of the refrigeration system is supported.

A regular check of the safety equipment ensures smooth operation of the system and protects against malfunctions in good time.

Cleaning the condenser ensures greater operational safety.

Cleaning the condenser helps to save energy. Condensers that are dirty can result in up to 10% higher energy consumption!

The optimally adjusted refrigerant charge quantity is the basis for a safe operation of your flake ice machine with high efficiency.
