PREMIUM
DORIN broadens its
semihermetic compressors
series showcasing “ECO
PREMIUM” range,
specifically designed for
R134a applications.
These new compressors
feature important energy
efficiency increase, thanks
to:
• remarkable increase in
compressor efficiency with
low condensing
temperatures (down to
10°C);
• appropriate selection of
high efficiency electric
motor;
• proper valve plate
dimensioning;
• fluid-dynamic analysis of
the internal flows, allowing
for pressure drops
decrease;
• inverter drive operation
with huge frequency range
(up to 90 Hz for certain
models).
R404A system
comparison
This new range is
particularly indicated for
medium temperature
commercial refrigeration
application, being a very
interesting alternative to
the traditional R404A
systems. In fact, compared
with the modest initial
investment linked to the
use of machines greater in
size, the use of Dorin
“ECO PREMIUM” range
compressors leads to
several benefits, such as:
• operating pressure
decrease, assuring higher
safety margin especially for
hot ambient installations;
• cycle COP increase;
• pressure pulses
reduction;
• noise level reduction;
• maintenance cost
reduction;
• lower GWP.
Thanks to the
aforementioned aspects,
short payback period of
such system are given,
thus providing excellent
annual running cost
reduction.
