Testbed-validated performance data

The excellent performance figures and the reliability of eChiller have been impressively demonstrated in the field over a period of 360 months. This operating period has resulted in energy savings of over 390,000 Euro (at 0,2 €/kWh) and 1.120 tons of CO2 equivalent emissions reductions (at 580 g/kWh for the year 2015, source: UBA).

In addition, the eChiller performance data have been validated on testbeds of reputable refrigeration technology manufacturers in Denmark and Italy.

Below, we have compiled a number of reference examples and application scenarios:


Efficient cooling of server rooms and computing centers

Application domain: Cooling of data centers and server rooms

Efficient cooling of data centers and server rooms

eChiller has been successfully deployed in the server rooms and IT equipment of Germany’s largest dairy plant, DMK Deutsches Milchkontor GmbH, and the Sparkasse Calw savings bank. The servers are cooled using 20 to 25 °C air chilled using eChillers.

And this is how it works:

  • Cold air is pumped through the servers and absorbs the heat generated by the electronic components
  • The warmed exhaust air is then cooled back down to the supply air temperature via a heat exchanger connected to the eChiller
  • Cooling (dissipating heat to the environment) via dry coolers and a brine closed-loop cycle

Long term deployment with top results – Cooling of two data centers

eChiller has been deployed at the Seckenhausen site near Bremen since the end of 2014 to dissipate the excess heat of a server room to the outside via an air-cooled dry cooler.
