5. 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
ammonia and carbon dioxide are essential essential.

6. Trends in Europe regarding HFC
Norway and Sweden:
Penalty tax on HFC
e.g., in Norway (+ 272.00 NOK/kg R134a (~ 35 €)
Denmark:
Larger than 10kg HFC charge
Germany:
Subsidies of up to € 200,000 for commercial
refrigeration systems using CO 2, NH3 or
hydrocarbons
Annual inspection with leak test for
HFC systems (1-4 times, depending on
filling quantity)
Luxembourg:
Decision according to TEWI value
Austria:
Larger than 20kg HFC charge
Switzerland:
>300 kW Qo HFC

9. New synthetic‘s available ?
Caught in
the act.
EU-rules is being like a rope around the neck
and there seems no fast solution in sight
regarding refrigerant for AC in cars. There is
still a need to tighten the rope towards the
Car manufactures in Europe
Car burning: Also Toyota was chocked to see how a Corrolla
burned in a DUH-test of the new chemical refrigerant 1234yf
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.
Highly flammable (selfigniting) and by adding water -> extremely toxic
Hydrogen fluoride gas is a severe poison that may immediately and permanently damage lungs and the corneas of the eyes

11. Why did we start the BluAstrum project?
Industrial refrigeration line Air conditioning line
(I Line) (AC Line)
° 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
