Sustainabillity

Natural refrigerants are the obvious choice as a sustainable & ecological alternative to HCFC & HFC's

All natural refrigerants occur in nature's material cycle.

They do not contribute to the depletion of the ozone layer and have no significant influence to the

greenhouse effect.

They have been used in food production and storage for more than 100 years.

Therefore, we are convinced that the natural refrigerants

and there seems no fast solution in sight


Calculation shows that every year 2500 ton

of R134a is leacking from cars in Europe.

It corresponds to 3,2 mio ton of CO2 or the

same as the exhaustion from 1,3 mio cars.

Car burning: Also Toyota was chocked to see how a Corrolla

burned in a DUH-test of the new chemical refrigerant 1234yf

What to do ?

GEA supports and deliver natural solutions


Industrial refrigeration line(I Line)

Air conditioning line(AC Line)

Why did we start the BluAstrum project?


° Existing chiller program was too industrial and complex° Increasing trend for natural refrigerants in AC and Industries° Increased competiveness by designing an outstanding, next

generation chiller, using latest innovative technologies

Time line

Company position

GEA Refrigeration Technologies Is already in leading position as the natural market pulls up

Offers products for minimizing carbon footprint


The goal

Maintaining the market leader position deliveringindustrial and AC chillers with natural refrigerants

by offering the newest technologies,


by offering the newest technologies, by facing the political discussion on greenhousegases and a growing demand for eco-technology.

How to achieve this ambitious goal?

° Minimizing carbon footprint by using natural refrigerants

By developing a highly competitive chiller withimportant features demanded by the market:


° Minimizing carbon footprint by using natural refrigerants° Highest efficiency by applying newest technologies° Small dimensions (door size and minimum footprint)° Low noise level

° Optimized for low TCO (total cost of ownership)

GEA RT core competency – the heart of refrigeration

° Better efficiency, speed controlled 1,000 up to 4,500 rpm,Automatic Vi-control integrated in compressor

° Less maintenance, long service life time of roller bearings° Easy maintenance, fewer connections° Less complexity, no external oil pump, no internal oil pump° Lower manufacturing cost, ground rotors, rotor-grinding


° Lower manufacturing cost, ground rotors, rotor-grinding technology

Evaporator and Condenser – the heart of efficiency

What has happened in the meantime?

BluAstrum has won the German Refrigeration Price 20 11

Wolfgang Sandkötter, Director of Development at GEA Grasso GmbH in Berlin, received on behalf of his team the German Refrigeration Prize in the category “Climate-Friendly Use of Refrigeration Systems in Production of Foods and Beverages”. The prize was presented to him by Katherina Reiche, Parliamentary State Secretary for the German Federal Ministry for Environment, Nature Conversation, and Nuclear Safety


We are convinced that BluAstrum will improve GEA ´s image as a supplier of environmentally friendly and energ y saving

Technologies and contribute to sustainable profitab le growth.
