Up to 45 kW cooling capacity 100% water as refrigerant No direct CO2 emissions Bis zu 30 % BAFA-Förderung

The eChiller35/45

This two-stage eChiller is available in the power classes 35 and 45 kW. In practice, it has been successfully cooling data centers, industrial processes and machines at well-known and satisfied customers for many years. Based on the unique Bluezero® technology, it works with water, the most natural refrigerant in the world. Convince yourself of the many advantages so that you can continue to operate successfully and sustainably in the future.


The eChiller35 and eChiller45

This water chiller offers cooling capacities of up to 35 or 45 kW. Together with their "big brother", the eChiller120, they are currently the only series-ready chillers worldwide with Bluezero® technology, which makes water usable as a refrigerant. Ideal areas of application are the cooling of Data centers, process cooling and machine cooling.

The integrated Bluezero technology offers very high energy efficiency with 0% direct CO2 emissions. Current F-gas legislation does not apply to water as a refrigerant. You save costs for refrigerants and maintenance - a sustainable and safe investment in the future.


Key data eChiller 35/45 – the efficient cooler

  • Up to 80% energy savings compared to conventional technology
  • Pure water as refrigerant (R718)
  • The F-Gas regulation does not apply
  • ERP ready
  • Cooling capacity at 35kW and chilled water at 22ºC / 28ºC.
  • Stepless capacity modulation between 10% and 200%
  • Works by directly evaporating water in a vacuum-tight closed loop


The technology - groundbreaking, highly efficient and climate-neutral

The unique and innovative Bluezero® technology is included in all chillers and enables water to be used as a refrigerant for a wide range of industrial applications. As of 2020, Bluezero® is officially registered as a trademark and can also be sold as a standalone technology for integration into OEM products. It is ideal for temperatures from 12ºC and here it offers excellent results in terms of performance and efficiency. Looking at this temperature range, there is simply no better solution for your cooling applications than Bluezero® - economical and ecological.
