According to the new F-Gas
Directive, by 2030, EU member
states must have completed
their gradual reductions of
CO2 equivalent emissions of
F-Gases by nearly 80%.
This is the basis of eChiller, the world’s cleanest and, with up to 80%
energy savings, economically most valuable centrifugal chiller. Find
more information on our homepage.
Ideal for modernizing your continuous industrial process cooling and
improving your computing center profitability.
Over the next few years, many refrigeration units will no longer
fulfill regulatory requirements that are coming into force. Per-
manently rising electric energy costs place an additional burden
on refrigeration. This makes forward-looking investments all
the more important today.

Sustainable refrigeration technologyRethink your strategy – It only makes sense
An excellent product
The eChiller provides the perfect answer to the EU F-Gas Directive, increasing environmental pollution and rising energy costs.
Water as a refrigerant meets even the most stringent standards – it fulfills all evironmental and safety regulations pertaining to the operation and service of conventional refrigeration systems.At the same time, its energy efficieny is unrivaled, exceedingconventional technology by 80%.
A real plus for your company – economically and ecologically
The eChiller100% water – 80% energy savings
The eChiller works by direct evaporation of water in a vacuum-tight system thatis hydraulically decoupled from the cooler and refrigeration application via brazeplate heat exchangers.
The TechnologyFuture-oriented, highly efficient and climate-neutral
The clever process
The energy saving feature
1. Evaporator: Water enters the evaporator. A small portion of the water evaporates and drains energy from the remaining water, causing it to cool.
2. ct turbo compressor: The water vapor is then compressed by the turbo compressor,which operates at up to 90,000 rpm, causing the vapor pressure and temperature to rise.
3. Condenser: The compressed water vapor condenses in the condenser, therebyheating the cooling water.
4. Expansion: The condensed water is fed back into the evaporator
The system interconnects the modules depending on the outside temperature, allowing the required coolingperformance to be achieved with a minimum of energy.
How the module works:
At the nominal operating point of 28/22 °C and 35 kW, eChiller has four operating modes that kick in as follows:
The eChiller comprises two identical modules that use the natural refrigerant water (R718).
FreeCooling: Cooling water temperature <18 °CBoth modules operate passively; maximum COP.
Stage I: Cooling water temperature 24 °C - 30 °CA single module generates the temperature boost.
FreeCooling+: Cooling water temperature 18 °C - 24 °COne module augments the cooling performance.
Stage II: Cooling water temperature 30 °C - 45 °CBoth modules generate the temperature boost in series.
Cost savings and environmental protection – Score two goalsin one using the sustainable eChiller refrigeration technology.
