GHM
A control system for complete water control and the most efficient use of water.
product overview
As a complete water controls solution, the GHM controller allows for the precise metering of water over the hydroBLU™ pads of our adiabatic heat rejection equipment. The GHM calculates the flowrate of water required for the wetting process based on load state and ambient conditions.
The GHM connects with the GMMnext fan controller to allow for optimization of both water and energy usage for any application.
Benefits at a Glance
EFFICIENCY MODE
Ensures the perfect balance between water and electrical power consumption. If efficiency mode is activated, the wetting controller looks for the most cost-effective operating point between fan speed and water volume.
FULL LOAD OPERATION
Boosting the capacity of the heat exchanger by increasing the amount of water used to keep the system running smoothly.
PARTIAL LOAD OPERATION
In phases of reduced demand, partial load operation ensures that only as much water as the pad can evaporate is used.
WET BULB CALCULATION
The system measures the outside temperature and humidity in order to determine the wet bulb temperature and ensure efficient water consumption.
METERED WATER
Optimal water demand is permanently calculated depending on the ambient and operating conditions, setting the control system to wet hydroBLUTM pads efficiently.
FROST PROTECTION
Automatically activated when temperatures are below 5°C, frost protection is used to avoid damage to the hydroBLU™ system.
CLEANING MODE
The lifetime of hydroBLU™ pads is increased through a process of soaking and cleaning them in specific intervals. This includes also a pre-cleaning cycle, activated before the wetting starts to run.
HYGIENE MODE
Hygiene mode ensures that during long phases in which the wetting is not used, the system is automatically drained in order to prevent the formation of bacteria.
