Company profile
C onstantly
growing all over the world
Uniflair was founded at the end of 1988 and quickly managed to conquer an
important position among the biggest manufacturers in the world of air conditioning
for technological application, as well as chillers and modular access flooring.
Initially it only dealt with the national market, however Uniflair’s expansion has
now reached Europe and the other continents. It currently has over 60 distributors.
The company’s considerable expansion has made it necessary to adapt its working
space. Thus, from the first factory measuring 1,200 m², Uniflair has recently moved
to a new site which, with a surface area of over 120,000 m², makes use of a
production area of 30,000 m², training rooms, conference halls and one of the most
innovative research centres in Europe.
R ese arch
and innovation
Innovation has always been the mainstay of Uniflair’s development:considerable
company resources have been invested in research into new application solutions
intended to assure product excellence with an unbeatable level of reliability. The
whole production and management system is run based on an ISO 9001 certified
quality model, Uniflair has also achieved ISO 14001 certification.

Products
C lose C ontrol - P recision A ir C onditioning
Any type of living organism requires a suitable environment in order to operate
at its best. Advanced technological applications need accurate and precise
management of the thermo-hygrometric environmental conditions which are
necessary to ensure correct operation and increased reliability. In order to respond
to continuous technological evolution, a precise and accurate air conditioning
system is fundamental since it is able, thanks to new technological solutions and
component innovation, to create the correct conditions for optimum operation of
the whole system. Uniflair precision air conditioning units are extremely reliable in
terms of operation and precision, they are environmentally friendly and particular
attention has been paid to energy efficiency.
Technical
cooling
- C ooling
systems
Combining avant-garde technology with energy efficiency while protecting the
environment at the same time is the challenge which has inspired Uniflair to produce
this new range of products designed for “technical cooling”. Air conditioning
technological environments, cooling industrial processes and providing comfort
cooling combined with high levels of performance are all types of applications
where the ideal solutions are chillers and heat pumps belonging to the technical
cooling series. Many years of experience combined with the company’s position
as a market leader in the air conditioning sector has enabled Uniflair’s designers to
make the technical and operational choices necessary to create optimum technical
excellency.
U nifl air M odul ar A ccess F loors
The development of new technology combined with the need to create new spaces
and modify environments has led to new architectural and operational demands
for designers. Uniflair has an avant-garde Modular Access Floor production line
which is able to meet each client’s specific needs. The annual production capacity
is more than 1.500.000 square meters and quality is ensured by a continuous
supervision control system at each manufacturing stage. Moreover, some of
Uniflair’s exclusive processes are patented. The aesthetic-functional value of each
building is increased by a wide range of flexible, innovative, practical and elegant
solutions suitable for any type of building context, ensuring added value for the
client.

Why Uniflair
E fficiency
and
R eliabilit y
The issue of energy continues to play an extremely important role regarding operating costs for modern systems. Uniflair’s range
of products makes it possible to guarantee maximum service reliability while cutting energy consumption to a minimum:
Indirect free-cooling
High efficiency refrigerants
Efficiency at partial loads (tandem)
“Oil-free” centrifugal compressors
with magnetic bearings
Modularity and flexibility
Inverter driven compressors
Optimized set-point
Double screw compressors
Less CO 2
A dvanced
controls
Uniflair produces the software for its units internally. This enables the company to equip each machine with a “tailor made”
control which manages all aspects of the unit.
Absolute control means:
• Precision: the units use advanced algorithms to accurately control the temperature of
the chilled water
• Reliability: each component is continuously monitored to guarantee it is always used
within operating limits and will signal any faults before breakdown occurs
• Local Area Network: Aquaflair chillers can “talk” to each other, resulting in excellent
control of multi-unit systems, managing all the cooling resources and units on stand-by
(either on a time basis or alarm)
• Connectivity: Uniflair microprocessor controls can “talk” to the most common supervision systems (Building Management Systems) including: Modbus, Bacnet, LonWorks,
Trend, Metasys, TCP/IP and SNMP

O ptimized
management
Management of the whole system allows energy consumption to be optimized and
strategies of integrated control to be implemented which would otherwise not be
possible.
Uniflair ‘s precision air conditioning units, Active Floor modules and chillers can be
linked together by a LAN, maximising the operating parameters and the real needs of
the system.
Particular attention has been paid to the management logic which is aimed at reducing
the energy requirement by means of a “tracking logic” for the current thermal load.
The temperature of the chilled water varies dynamically in such a way as to minimize
compressor consumption and the use of free-cooling, maintaining the desired
temperature within the room.

Reduction in sound pollution is one of the most critical factors designers are called on to solve when choosing plant systems.
Uniflair chillers offer low-noise solutions with extremely low acoustic impact thanks to:
• Acousti-composite fans with high efficiency and low acoustic impact
• Extra-large air side exchangers
• Specially devised and implemented algorithms which control the rotation speed of the fans
• Tested, optimised compressor insulation and housing

When a system is used for technological or industrial processes which operate all year round, it is important in terms of energy
saving to use solutions which exploit these conditions. Chillers equipped with free-cooling devices not only reduce energy
consumption compared to traditional systems but also limit CO 2 emissions into the atmosphere, contributing therefore to
reducing global warming.
When the external temperature is low enough, the free-cooling system produces chilled water using external air only,
significantly reducing energy consumption since it is limited to the fans.

Intelligent Free-cooling
Direct expansion mode
The need to install a stand-by unit can be exploited to increase the free-cooling capacity.
By interconnecting the circuits of the free-cooling units it is
possible to make the water flow through all of the available
exchangers therefore further decreasing energy consumption.
Additional annual energy saving
• Compared to traditional Free-cooling:
up to 7% depending on the climate
• Compared to a traditional system: up to 50%

Created for applications where the use of anti-freeze solutions are not permitted, this solution, thanks to an intermediate
heat exchanger, isolates the principal hydraulic circuit from the free-cooling circuit.
Careful selection of the intermediate heat exchanger allows the delta T to be limited to only 2°C, reducing therefore the
energy drops which are intrinsic to this system.
