GUNTNER ADIABATIC HIGH DENSITY

Adiabatic Operating Principle
Güntner’s ADC HD can be used either wet or dry. Both modes offer excellent dry cooler performance with a small footprint and low operating costs. The cooling limit, i.e. the theoretically best possible return temperature for the ADC HD is tied to the wet bulb temperature of the ambient air at the heat exchanger. Our experts will configure the ADC HD specifically for your application and optimize it for use in your system. This is the only way of optimally dimensioning the dry coolers and minimising the cost of operating the entire system.

Dry or wet – performance as required

Adiabatic operating principle
Güntner’s ADC HD can be used either wet or dry. Both modes offer excellent dry cooler performance with a small footprint and low operating costs. The cooling limit, i.e. the theoretically best possible return temperature for the ADC HD is tied to the wet bulb temperature of the ambient air at the heat exchanger.

Our experts will configure the ADC HD specifically for your application and optimize it for use in your system. This is the only way of optimally dimensioning the dry coolers and minimising the cost of operating the entire system.

The smart hydroBLU™ control unit continuously records the amount of water applied, the speed of the fans and the state of the ambient air. This reduces your operating costs without any loss of performance, thus saving you money. The necessary information for this such as the fan speed is read out from Güntner Motor Management GMM via the bus communication. This speed information can alternatively be transmitted using a 0 – 10 volt signal.

Efficiency mode
The hydroBLU™ is also capable of checking the operating costs during oper-ation. This provides the basis for an integrated cost management function, which continually decides whether applying water or changing the speed represents the more cost-saving and therefore more efficient mode of oper-ation. To this end, the water quantity is constantly recorded in this system.

Safe and hygienic operation

The clever design of the ADC High Density takes into account the recognized technical rules when it comes to the hygienic operation of evaporative cooling systems. The pre-cooling unit with humidification fluid is completely separate from the heat exchanger.
The humidification controller supplies the easily replaceable humidification pads only with the amount of water needed depending on the particular situation. This minimizes water consumption and prevents standing water. In the event of inactivity, the pre-cooling unit is automatically drained. The factory-fitted feed water line can also be drained or ventilated via the unit.
Güntner offers its customers added value on three levels: expert advice over the entire life cycle of units, safety thanks to carefully constructed units equipped with suitable control systems and certified employees.
