Hybrid Dry Cooler High Performance

Features

The HTK Hybrid High Performance  is a combination of air-cooled dry coolers and closed circuit evaporative cooling systems. Thus the hybrid dry cooler is a high-performance unit with low operating costs that combines the advantages of conventional dry coolers with the efficency of wet cooling in a single product.

Your advantages

  • Low cooling water temperature
  • Little space requirement
  • No contamination of the primary circuit
  • Up to 10 dB quieter than a cooling tower
  • Hygienic operation with little maintenance work
  • Perfect access for inspection and maintenance
  • Plume-free throughout the year Construction can be modified to suit your particular premises
  • Modular series with a range of dimensions and heights
  • Height: 3 – 5 m
  • Length: 3 – 12 m
  • Power range: 100 – 4,000 kW

JAEGGI heat exchangers and Güntner condensers for the ebm-papst distribution centre

The new building complex for faster ebm-papst logistics processing in Mulfingen-Hollenbach saves 83 percent more energy than required by the 2014 German Energy Saving Regulations. This pioneering project has already gained the German company the highest possible award (Platinum) for sustainable construction. Both a JAEGGI HTK Hybrid Dry Cooler and an air-cooled Güntner GVD V-SHAPE Vario condenser ensure the dissipation of heat that cannot be used.

Saving 50 million Swiss francs on energy costs in 20 years with free cooling

Saving 50 million Swiss francs on energy costs in 20 years with free cooling

The Swisscom data centre in Bern-Wankdorf is one of the most efficient in Europe thanks to its use of innovative energy technology, using 90 percent less energy for cooling compared with conventionally equipped data centres. Some 84 percent of the energy is thus used for the IT infrastructure and only around four percent for cooling purposes as well as another four percent for ventilation. Swisscom relies on hybrid coolers from JAEGGI in all construction sections in its modular data centre.

Groundbreaking concept for highest energy efficiency

Groundbreaking concept for highest energy efficiency

The West Cambridge data centre, one of the most ambitious IT projects in the higher education sector, makes its server capacities available to the renowned Cambridge Research Community. The data centre is cooled by only three hybrid dry coolers from JAEGGI and thus without compressor. In 2016, the data centre received the prestigious Public Service Digital Delivery Award for the innovative engineering concept.

GlaxoSmithKline Biologicals - JAEGGI hybrid dry coolers with a combined cooling capacity of 11 MW

GlaxoSmithKline Biologicals - JAEGGI hybrid dry coolers with a combined cooling capacity of 11 MW

The former Sächsisches Serumwerk, located in the heart of Dresden, Germany, was acquired in 1992 by

British drugmaker SmithKline Beecham. In 2000, the company merged with Glaxo Wellcome and has operated the factory since 2008 as GlaxoSmithKline Biologicals. This plant manufactures the influenza vaccine called Influsplit SSW® (trade name Fluarix®outside of Germany) which is distributed to nearly 70 countries worldwide. The GSK Biologicals complex now houses eight JAEGGI hybrid dry coolers with a combined cooling capacity of 11 MW (2,500 evaporative tons).

The DESY Research Center- 15 JAEGGI hybrid dry coolers with an aggregate cooling capacity of 25 MW

The DESY Research Center- 15 JAEGGI hybrid dry coolers with an aggregate cooling capacity of 25 MW

DESY is a world leader in particle accelerator research. At their Hamburg, Germany facility, the company designs, builds and operates large particle accelerators to investigate the structure of matter. The work that takes place there is vital for breakthroughs in fields ranging from medicine to material research. The DESY Hamburg facility had multiple cooling needs including the PETRA III X-Ray, the DESY II experimental circle particle accelerator and its magnetic circuits, and the facility’s centrifugal chillers. To meet these diverse demands the company installed fifteen JAEGGI hybrid dry coolers in various sizes with an aggregate cooling capacity of 25 MW (5,687 evaporative tons).
