MAJA RVH-NH3 Flake Ice Machine

Highly sustainable flake ice production

  • Hygiene concept for food-safe flake ice production
  • Compatible with direct ammonia refrigeration systems
  • Natural refrigerant R717 – less environment impact
  • Wide range of customized accessories and options

Information

The flake ice machines MAJA RVH-NH3 without condensing unit are designed for direct operation with an ammonia / R717 multicompressor refrigeration unit. For ecological and sustainable ice production projects.

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.

Refrigeration

  • Optimum energy efficiency – increased power density: Compared to traditional refrigerants, e.g. R404A, the direct ammonia operation brings more power density, thus increased ice output compared with the same machine scale.
  • The RVH 12000 NH3 consists of two separately operated rotating evaporator units. Advantages: individual control of ice output according to varying needs and high operational safety.
  • Electronic evaporation pressure regulation for optimum efficiency.
  • Eco-friendly flake ice production and excellent ecological impact by using the natural refrigerant.
  • R717 (ammonia / NH3) for flake ice production. R717 consists of the elements nitrogen and hydrogen, which are natural parts of the atmosphere.
  • No influence on the destruction of the ozone layer, no influence on the greenhouse effect: Ozone depletion potential ODP = 0, Global warming potential GWP = 0.
  • Installation conditions: Existing R717 multicompressor refrigeration unit working in pump operation, meaning the refrigerant becomes liquid and circulates.
  • Ammonia temperature approx. -30°C.
  • Pump pressure 2 - 4 bar.
  • High safety standard: Integrated safety system with gas detector and automatic cutoff and blockage in case of leakage.

Easy operation – convenient ice handling

  • Easy operation by Control Panel Touch (control unit with touch display):
    Individual placing of the control unit.
    With timer function for freely programmable production and cleaning cycles (with option MAJA-SCS self-cleaning system), for having the right quantity of fresh flake ice at your disposal exactly in time. 

Accessories

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.

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.

Service

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.
