- High system competence
Dry operation
- With no wetting of the unit it operates like a conventional finned dry cooler
- Energy is dissipated to the ambient air via convection
Wet operation
- For high external temperatures or systems subject to higher cooling loads
- Even without directly wetting the heat exchangers, the fluid can be brought down below the ambient temperature
- Energy dissipated by convection
Technical details
Adiabatic operating principle
JAEGGI hybrid dry coolers can be operated either wet or dry.
Both modes can provide 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 Hybrid Blue® is tied to the wet bulb temperature of the ambient air at the dry cooler.
Our experts will configure the ADC Hybrid Blue® specifically for your application and optimise it for its intended operation in your system. This is the only way of ideally dimensioning the dry coolers and minimising the operating costs of the complete system.

Technical data for the ADC Hybrid Blue
Multifunctional use of humidification pads
Dry operation without humidification pads
- Humidification pads can be installed to reduce energy consumption
- Reduced pressure loss, leading to savings of up to 10 %.
- Easily removed for dry operation
- Pads are relocated on the cooler, no need to store them elsewhere
- Frames protect the pads from damage
- Very low water consumption because dry/wet switchover is set at a high level
- With no wetting of the heat exchanger it operates like a conventional finned dry cooler
- Energy is dissipated to the ambient air by convection

Hospital makes use of efficient water and energy input for cooling
It is not all about investment costs when it comes to the "right" dry cooling technology. This is why the Fürstenfeldbruck Hospital in Germany calculated very tightly, and the persons in charge opted for the adiabatic state-of-the-art ADC dry coolers from JAEGGI as the life cycle costs were ultimately decisive for the investment. Yet the recently installed units offer another advantage: Due to their design, the low-maintenance JAEGGI ADC dry coolers do not fall within national relevant regulations but meet the stringent requirement of the German VDI guideline 2047-2 and also comply fully with ACOP L8 and HSG274 Part 1.

Cool air conditioning for the EMEA headquarters of DuPont de Nemours
The international science company DuPont de Nemours counts, for its Swiss location in Geneva, on JAEGGI ADC adiabatic coolers which precisely fit into the ambitious sustainability concept of the company. Four coolers with a total capacity of 2,640 kW efficiently cool the office building.

Adiabatic dry cooler JAEGGI ADC in trigeneration system
In the town of Zülpich, located in the German federal state of Northrhine-Westfalia, a company producing food additives relies on economic trigeneration. The waste heat of the cogeneration unit feeds an absorption liquid cooler that cools an office building. The dry cooling of this building, in turn, is performed by two ADC coolers from JAEGGI as they meet stringent hygiene requirements and this, as a rule, without water treatment.

Accessory
All controls possible
- GMM step
- GMM phase cut
- GMM sincon
- EC fans with GMM EC
- Wired ready to use
AxiTop Diffuser
The AxiTop diffuser improves airflow at the fan outlet. This accessory makes it easier to overcome the pressure drop at the air-side. With skilfully adapted geometry the fan can achieve the same performance at lower speed. Lowering the speed reduces both noise emissions and power consumption.
Epoxy coating
The service life of finned heat exchanger depends very much on the concentrations of the various substances in the air, and hence the application. The service life of these heat exchangers can be significantly increased by using epoxy-coated fins. Epoxy resin is a thermosetting plastic which, once hardened, exhibits high strength and chemical resistance.
