Flake ice machine (rotating evaporator) for direct operation with ammonia NH3 (R717) operation. The direkt operation with NH3 guarantees best efficiency. NH3 is appreciated for its environment-friendly caracteristics: ozone depletion potential ODP = 0, global warming potential = 0. With integrated safety system (gas detector and automatic cutoff and blockage in case of leakage. With electronic evaporation pressure regulation. 

Conditions for the installation of a RVH with NH3 direct operation:

  • Existing NH3 multicompressor refrigeration unit
  • NH3-multicompressor refrigeration unit must work in pump operation, that means the refrigerant circulates in liquid form.
  • Ammonia temperature approx. - 30°C
  • Pump pressure 2 - 4 bar 

Ice output 14000 kg / 24 h 

This machine type is part of the new HY-GEN flake ice line. The HY-GEN products have been designed in a completely new way and even the smallest screw is drafted to allow the production of flake ice that meets with strictest hygiene requirements. The core piece is the innovative evaporation tank in plastics, which can be easily removed for manual cleaning. Moreover, the evaporation tank is free from integral built-in parts, which make systematic cleaning complicate and difficult. Regarding water supply, MAJA trusts in innovative DVGW-compliant systems. 

With the HY-GEN-philosophy, MAJA does not leave hygiene to chance any longer!
