GMMnext
The intelligent GMMnext control system increases the economic efficiency of your entire refrigeration system.
product overview
With the integration of GMMnext, the performance of the entire refrigeration system is optimized: The smart control system is designed to automatically adjust the operation to reflect changes in load, weather conditions, and operating requirements. This allows to cut energy consumption by up to 30% and to maximise the service life-time of your cooling system, whilst continuously ensuring a safe and reliable operation.
The GMMnext controller can be seamlessly integrated into building management systems via a suitable interface module. This makes the GMMnext controller an integral part of your facility management. In addition, immediate access to historical and live data is provided, permitting performance analysis to improve operations.
Benefits at a Glance
LCMM
In phases of reduced demand, partial load operation (Low Capacity Motor Management) ensures energy savings and avoids performance fluctuation. This is thanks to switching off individual fans or fan groups, by using machine learning.
SLCMM
In the event of extreme low-ambient temperatures, SLCMM mode (Super Low Capacity Motor Management) generates an artificial air cushion in order to minimize air flow and effectively prevent natural convection. As a result, the heat exchanger’s efficiency is optimized.
SETPOINT
Programming of multiple setpoints allows to customize the control system to your specific needs.
NIGHT SETBACK
During night time, the cooling system can operate at partial load. This does not only save energy, but also drastically reduces noise emissions.
BREAK-FREE MODE
Automatically activated when temperatures are below the freezing point, this mode prevents ice formation on fan blades, thus ensuring smooth coil operation.
BYPASS MODE
In the event of controller failure, emergency operation is automatically switched-on to keep the cooling system running smoothly.
CLEANING MODE
In order to keep the heat exchanger coil clean, fan rotation is reversed at regular intervals.
MAINTENANCE CYCLE
Maintenance mode ensures that during long phases in which the unit is not operating, the fans are switched-on in regular intervals in order to prevent damages.
