GEA Grasso GmbH
High-efficient chillers for air conditioning and industrial cooling
Grasso BluAstrum
GEA Refrigeration Technologies
The new BluAstrum series of Grasso chillers provides compact-
ness and efficiency at its best. For the heart of the completely
new chiller range GEA developed a high-efficiency compressor
series with speed-control, frequency inverter, and variable Vi for
maximum full- and partial-load efficiency. As a result BluAstrum
sets new benchmark for ESEER values. The advanced control
system GSC TP ensures reliable operation with maximum effi-
ciency with customer oriented communication features. Its com-
pactness enables customers to replace older chillers easily with
this high efficiency Grasso chiller range. As an option, a new
housing is available to reduce noise levels even further. The fi-
nal series of the new design will comprise six chiller types with
a capacity range from 500 kW to 2,000 kW with operating con-
ditions between -15 °C and +15 °C. Grasso chillers are using only
natural refrigerant ammonia for sustainable and environmental
friendly solutions.
System control GSC TP
The new Grasso System Control GSC TP ensures a reliable opera-
tion of the chiller with an easy menu structure and extended
functionalities. One of the major novelties is the optimized
sequence control and the easy network setup.

Evaporator with integrated separator
The new flooded evaporator design combines compactness and
exceptional high efficiency by offering low approach tempera-
tures. The evaporator is equipped with an internal liquid separa-
tor and is connected to an automatic oil return system reutilizing
the oil.
Condenser
The highly efficient condenser works at very low approach tem-
peratures that minimize the TCO.
Expansion control system
The chiller is able to utilize floating condensing temperature and
the liquid level is controlled at a minimum level to minimize the
entire refrigerant charge and to maximize efficiency.
Enclosure
As an option a compact enclosure can be delivered offering a re-
duced noise level.
Grasso CM - the new high efficient
screw compressor
The new screw compressor Grasso CM is characterized by a small
size and high efficiency. The Vi adoption ensures optimum effi-
ciency at all operating conditions. The generous internal flow
paths give the compressor a very low noise level and the simple
oil circuit with less mechanical parts lowers the service demand
and the TCO (Total Cost of Ownership).
Variable speed drive (VSD)
The variable speed drive operation ensures the best possbile part
load efficiency and steady process temperature at all capacity
levels. The starting current is very low compared to traditional
starters.
