Water-cooled chillers and heat pumps with R134a

Class   A   energy   efficiency   on   all
models,   refrigerant   R134a   equipped
screw   compressors,   an   advanced
evaporator  and  sophisticated
microprocessor  all  combine  to  make
Aquarius plus the choice solution for
the most discerning industrial user.
Water-cooled chillers and heat pumps with R134a

ENERGY EFFICIENCY CLASS A
The  high  energy  efficiency  levels  offered  by  Aquarius plus  
have   been   achieved   thanks   to   meticulous   design   and
accurate  selection  of  sophisticated  components  aimed  at
reducing operating costs. All models feature “Class A” energy
efficiency,  i.e.  they  offer  EER  values  in  excess  of  5.05  in
compliance with EECCAC standards. Continuous compressor
capacity control, together with the use of up to 2 compressors
in 2 independent circuits and electronic thermostatic valves,
offer excellent partial load energy efficiency levels.
R134a ENVIRONMENTALLY FRIENDLY REFRIGERANT
Aquarius plus   features  R134a,  a  chlorine-free,  zero  ozone
depletion   potential   (ODP)   refrigerant   with   significant
environmental benefits. R134a’s reduced operating pressures
and   temperatures   ensure   high   compression   levels   with
reduced electrical power consumptions.
VERSIONS
N - standard;
SSN - super silent.

HIGH TECHNOLOGY SUPPLIED AS STANDARD
The  electronic  thermostatic  valves,  supplied  as  standard  on
almost  all  models,  control  the  refrigerant  flow  by  means  of
an  actuator  on  the  basis  of  the  pressure  and  temperature
values  measured  by  sensors  in  the  refrigerant  circuit.  The
thermostatic  valves  ensure  unparalleled  cooling  capacity
precision   whilst   simultaneously   extending   the   operating
limits  of  the  units.  Thanks  to  these  features  Aquarius plus  
ensures highest energy efficiency levels.
HIGH EFFICIENCY EXCHANGERS
The   direct   expansion   shell-and-tube   evaporators   and
condensers,  optimised  for  R134a,  are  amongst  the  most
technologically  advanced  on  the  market.  Thanks  to  their
construction, and the facility for periodic maintenance, they
provide  stable  and  reliable  operation  in  even  the  harshest
industrial  applications.  All  evaporators  are  protected  from
freezing by means of the microprocessor’s antifreeze function
and a differential pressure switch.
ACCESSORIES
Compressor protection by means of automatic cut-outs;
Condensing pressure control kit;
Anti-vibration dampers kit;
Replicated remote user terminal kit;
Supervisor kits;
Combinable cooling tower or dry cooler available on
request;
Antifreeze heater;
Total  or  partial  recovery  exchangers  (50%  or  100%  of
rejection heat);
Pressure control valves kit.

PERFECT TEMPERATURE CONTROL
Continuous  capacity  control  combined  with  the  electronic
thermostatic  valves  allow  perfect  control  of  the  cooling
capacity output and hence the water outlet temperature, this
being a fundamental requirement in the precision cooling of
industrial processes.
RELIABLE IN EVEN EXTREME CONDITIONS
Aquarius plus  units are designed to ensure reliable operation in
the typically demanding conditions of industrial applications,
thanks to the availability of up to 2 independent refrigerant
circuits,  generous  operating  limits  and  the  use  of  highest
quality compon
