Optima INV DXA 16V1A1 + 1x AMAE6

The OPTIMA product family from Airsys is designed specifically for use
within small, medium and large data centres, as well as for process and
cleanroom applications.

OPTIMA units combine precise temperature and humidity control with
outstanding reliability.

OPTIMA INV-DXA units feature EC fans and inverter compressor technology,
using remote air-cooled condensers, for optimised energy efficiency.

1 Precise control

The control accuracy for temperature is ±1° C and for relative
humidity is ±5%.

7 Scroll Compressor

OPTIMA (DXA & DXW) units are equipped with scroll
compressors which produce less vibration, lower noise and
greater efficiencies.

2 Various supply air arrangements

Supply air arrangements include top discharge (upflow)
and bottom discharge (downflow). Return air arrangements
include top return, bottom return, front return and rear return,
to meet all site requirements.

8 Isolated control panel

All the electrical and control components are installed in an
isolated control panel with orderly wiring and clear labelling,
meeting the IEC standards.

3 Corrosion-proof

The unit framework is provided with a corrosion protection
treatment. The treatment is sufficient to provide protection
for a 15 year life cycle for inland installation. If necessary,
the treatment for sea air environment can be supplied as an
option.

9 Forced dehumidification system

The dehumidification process occurs through decreasing
the evaporator coil surface temperature or reducing the air
flow across the coil. Variable-capacity systems come with
power monitoring tools that are displayed locally, in addition
to being available via remote access. Power monitoring can
be used to measure efficiencies across systems, regions and
networks. This feature can be used for predictive maintenance.

4 Easy maintenance

The technical compartment housing the compressor,
humidifier, control and safety devices is separated from
the air flow, enabling ordinary service and preventative
maintenance to occur during operation.

10 Electrode Humidifier (optional)

An electrode humidifier, controlled by a microprocessor,
monitors and adjusts the humidifying capacity precisely,
while the water quality monitoring and wash extends the
maintenance interval, prolonging the working life of the unit.

5 EC fan

Highly efficient EC fans are supplied with OPTIMA products.

11 Electric Heater (optional)

The construction of the electric heater element (stainless
steel pipe with wrapped fins) allows for a reduced operating
temperature, therefore eliminating ionisation, and avoiding
unpleasant odors

6 Air filter

A washable, easily maintainable and durable G4 class air
filter is a standard configuration for the OPTIMA range. With
optional air pressure switch, a clogged filter alarm can be
triggered when the filter is dirty.

12 Self-diagnosis

All the microprocessor-connected components are
continuously monitored and controlled and, in case of
malfunction, the unit is shut down and the fault is shown on
the display.

Optima.INV-DXA

Air cooled direct expansion system (DXA)

Heat from the indoor air is transferred to the refrigerant at the evaporator coil and rejected to the outside air via the air-cooled
condenser.

Air cooled direct expansion (DXA) includes throttle, evaporator coil, scroll compressor and refrigeration piping configuration

Air cooled direct expansion with indirect free cooling (FC.DXA)

The FC.DXA unit is a dual-circuit system combining DXA heat-rejection with indirect free cooling (FC). The circuits are independent.

When there is a call for cooling, and the difference between indoor and ambient temperatures is acceptable, the FC unit will run to provide
indirect free cooling through rejecting heat via a dry cooler. Only when free cooling capacity is insufficient to meet the cooling demand will
the DXA unit start up mechanical cooling. Reduced run hours of the DXA system through the use of the FC unit saves energy.

Air cooled direct expansion with double cooling source (DC.DXA)

The DC.DXA unit is a dual-circuit system offering both DXA (air cooled) mechanical cooling and chilled water cooling (CW). It
contains two independent cooling circuits with different heat-rejection methods for redundancy.
