With a reduced refrigerant capacity of less than ten kilograms, the AMONUM can be deployed in flexible fashion. In addition, the chiller is compact in size and features individual power adjustment as well as a comprehensive safety concept. It is suitable for brine applications down to -21 degrees Celsius, but also for process cooling and climate control up to +16 degrees Celsius.
