HIGHLIGHTS
6 Smardt TA-class Air-cooled Chillers
CORROSION PROTECTION
The TA-class chiller range has been designed with hostile
environmental conditions in mind, utilizing a range of
corrosion-resistant materials and industry-leading coatings.
It is intended that this manual be used with the applicable
installation drawings and wiring diagrams supplied with
your chiller. The information provided is general in nature
and is subject to change as part of Smardt’s commitment
to continuous product improvement. For specific
application information, contact your nearest Smardt sales
representative.
ENVIRONMENTALLY RESPONSIBLE
All TA-class chillers utilize non-toxic refrigerants with zero
ozone-depletion potential. Additionally a range of low
GWP HFO refrigerants are available, compliant with long
term EU F-gas regulations.
ADAPTABLE BY DESIGN
The configuration of each AE TA-class base model is
extremely flexible in performance and footprint, and can
be adapted to suit any air-cooled application.
The AE TA-class extendable condenser design allows
for a range of different efficiency options based on job
location, application and critical operating environment.
In addition, an extensive range of performance, functional
and connectivity options are offered - all specific to project
application and customer requirements.
The AE TA-class chiller range features a highefficiency extendable condenser, with multiple
performance options, packaged on a compact, yet
robust structural frame.
OIL-FREE COMPRESSOR TECHNOLOGY
At the core of all Smardt chillers is an oil-free Danfoss
Turbocor® compressor, featuring magnetic bearing
technology. With no oil to compromise heat exchanger
performance, and no friction losses associated with
conventional compressor bearings, Smardt chillers are
able to achieve exceptional full- and part-load efficiencies.
This ultra high speed technology eliminates up to 99% of
compressor induced vibrations, and dramatically reduces
the sound levels emitted by the chiller.
HIGH EFFICIENCY
In addition to its compressor technology, the AE TA-class
utilizes high performance aluminum/copper coils and
industry-leading EC fan technology as standard to deliver
a highly-efficient refrigeration circuit. All Smardt chillers use
premium flooded shell and tube heat exchangers which
have superior efficiency and reliability to plate and frame
or DX heat exchangers.
FEATURES AND BENEFITS

DURABLE FRAME CONSTRUCTION
An all-new space frame has been specially engineered as
the platform for the AE TA-class range of chillers. Substantial
reductions in embodied energy have been achieved
through a refined design, resulting in a rigid, yet lightweight
structure. This design provides a strong and durable frame
for worry-free lifting, installation and longevity.
CONTROL SYSTEM
Proven across years of industry experience in oil-free chiller
operation, Smardt’s advanced chiller controller is designed
to optimize the performance and capabilities of the AE
TA-class chiller range. Capacity can be reduced to as
little as 10% of full-load capacity. Simple integration with
building management systems via MODBUS is provided as
standard.
WEB-BASED CONTROL PANEL
The Smardt Control provides a web-based alternative to
traditional hardware controls. Using the HTML-based web
panel software in combination with the local touchscreen
interface display gives the customer both the ease-of-use
of a traditional control panel and the flexibility of a web
panel. The web panel software is installed on any digital
device (e.g., cell phone, tablet or computer) running a web
browser with access to the local network or via a secure
VPN connection. The interface software is installed on
the chiller controller. Switching between different control
panels is as easy as following a web link. Smardt offers
a modem connection option so any device connected to
the internet can remotely access the chiller via a secure
password protected connection.
SERVICEABILITY
All Smardt chillers are available with refrigerant isolation
valves on both sides of serviceable components, to
minimize ongoing maintenance requirements. This
facilitates servicing without the need to pump down the
entire unit, and in most cases can be undertaken while the
chiller remains operational. The majority of serviceable
components are readily accessible from the perimeter
of the unit, with each compressor easily accessible in
its weather resistant cover. The controller interface is
conveniently housed in a separate lockable enclosure
located between condenser coils where it is shielded from
rain and sun glare.
RELIABILITY & REDUNDANCY
With the experience of more than 8000 oil-free centrifugal
chillers now installed worldwide, Smardt chillers offer
outstanding reliability - unsurprising when an estimated
80% of all chiller field problems relate to failures in the
compressor oil-return. On multiple-compressor models,
mechanical and electrical isolation provides significant
redundancy and failsafes. In the event of a compressor
outage, Smardt’s controller will automatically adjust its
logic to continue serving the chilled water load with the
remaining available compressors. Should a compressor
require servicing, it can be quickly and easily isolated, even
removed, without stopping the chiller.
PACKAGED CONSTRUCTION
All Smardt chillers are factory assembled and tested,
ensuring trouble-free start-up and commissioning.

APPLICATION CONSIDERATIONS
APPROPRIATE CLIMATE
Humidity has little effect on the efficiency of an air-cooled
chiller, therefore giving the AE TA-class the greatest
advantage in high-humidity environments.
For applications involving lower humidity, consider
Smardt’s EE range of E-Class high efficiency, oil-free,
purpose built evaporative chillers.
CHILLED WATER REQUIREMENTS
All external pipework must be self-supporting, and aligned
to prevent strain and distortion on the chiller’s headers and
couplings.
EVAPORATOR WATER CIRCUITS
The chiller performance and efficiency can be adversely
affected by contaminants in the water circuit. As such,
strainers should be located on the inlet side of the
evaporator.
The water circuit should be arranged so that the pumps
discharge through the evaporator, with the return water
to the chiller connected to the lower connection of the
evaporator.
FLOW SAFETY INTERLOCKS
Differential pressure (DP) transmitters enable the chiller
to shutdown in the event of low or high flow through
the evaporator and are fitted as standard on all Smardt
chillers.
An additional field-supplied chilled water pump interlock,
or a VSD interlock signal s required on all installations.
If the chiller is intended for an application using variable
chilled water flow, please confirm the appropriate cut off
point with Smardt.
