 The Group
The LU-VE Group name has become the international reference
point for all that is best in the design, production and sales of
heat exchangers and other components for equipment used
in commercial and industrial refrigeration, air conditioning,
industrial applications and close control air conditioning.
The LU-VE Group of today, with its headquarters in Uboldo
(Varese), Italy, has been made possible thanks to a continuous
process of cultural and technological innovation starting in 1928
and still continuing strongly now.
The strength of the Group lies in its 9 production facilities and
sales companies, in 12 countries.

The important numbers are:

• more than 1450 highly skilled employees
• 340,000 m2 of total surface area (more than 140,000 m2 covered)

LU-VE S.p.A - Uboldo (Va), Italy

LU-VE S.p.A. is the holding company of LU-VE Group.

In 1985 LU-VE S.p.A. acquired Contardo S.p.A., established in 1928.
Production began in 1986.
LU-VE quickly made its mark thanks to high standards of quality, new solutions designed in its own
laboratories and to the care taken with the appearance of its products. (Beautiful outside - Revolutionary inside).
It has been the first company in the world to apply avant-garde solutions to commercial and industrial refrigeration:

• grooved tube technology • specialized heat exchange surfaces • certified performance levels
• innovative materials and colours • advanced design

The success of LU-VE in the international market stems from its research and development policy, its
great respect for the environment and its rigorous ethical and commercial principles.
In 2000, LU-VE was the first company in Europe to attain the prestigious Eurovent “Certify-All”
certification for the entire range of its products: unit coolers, condensers and dry coolers.
LU-VE and the Group have introduced new ways of conceiving and constructing products for refrigeration,
air conditioning and industrial applications, creating new technologies which have then gone on to
become the benchmark for the entire industry.

 Product configuration

Heat exchanger
LU-VE Group has always led the field
in the creation of very high efficiency
heat exchangers.
This has been made possible by
the use of sophisticated methods of
numerical simulation (CFD), capable
of predicting with precision the
fields of pressure, temperature and
velocity which are generated within
the heat exchanger, thus optimizing the heat transfer coefficient and
minimizing pressure drop.

In addition to numerical analysis, research activities are conducted in

the experimental laboratories of LU-VE Group, which are equipped
with:

• 3 climatic test chambers to measure the capacity of the exchangers

• 2 tunnels to measure the characteristic curves of the fans and the
relative electrical power draw
• 1 tunnel to measure heat exchange coefficients and air side pressure
drop of the exchanger
• Plant to measure heat exchange coefficients and internal tubes side
pressure drop of the heat exchanger
• 1 semi-reverberation chamber to measure sound level.

The heat exchanger geometry used in these machines - designed in

line with the most modern dictates of Computational Fluid Dynamics
enables very high capacity of heat transfer and power density to be
achieved. This means that we can offer a product which can reduce
dimensions, increase energy efficiency and minimize the amount of
internal fluid (a very important feature if hazardous fluids are used).
The condensing heat exchangers have special tubes with internal
helicoid grooves which increase heat transfer efficiency.
The great versatility of its construction enables optimized solutions to
be identified for different applications.

8
 Construction materials
The product has copper tubes and aluminium fins. The tubes are
mechanically expanded to guarantee the best contact between tube
and fin.
The headers of the dry cooler version are made of copper with an
aluminium floating flange attachment.
The headers of the condenser version are made of copper or carbon
steel depending on the application.
The casing of the heat exchanger is made of galvanized steel (to UNI
5961 standard), polyester-powder coated, colour RAL9003.
Corrosion resistance in compliance with EN ISO 12944, classification

In this configuration the fan-motor is a single piece and has several
advantages: compact design, excellent aerolic and electrical efficiency,
lightness, and it is easy to replace.
Insulation class F, protection grade IP 54. On request, fan-motors can
be painted and the windings double-impregnated for use in especially
severe environments.
These fans can be regulated by cut-phase controller or inverter. In the
latter case, the inverter must have sinusoidal filters between phase and
phase and between phase and ground.
On request, fans with electronic (EC) motors can be fitted to reduce
energy consumption (see dedicated manual).
Maximum reliability thanks to the numerous fans, which limit loss of
performance in the event of one motor failing.
Maximum simplicity of replacement without the need for lifting
equipment.

supplied with different grades of mechanical and electrical protection
depending on the intended type of use. These motors can be regulated
by inverter.
In this configuration, the fan group can be best suited to the needs of
the plant, permitting high levels of air quantity to be achieved and thus
maximizing heat exchange capacity at equal dimensions.

guarantee complete drainage of the heat exchanger (a special version is
available with extra drainage header).

13
 Control and regulation systems
The machines can be supplied with different electrical
configurations for the various plant requirements, both at the
level of electrical panels and also for speed controllers capable
of modulating the capacity of the heat exchanger depending on
conditions in order to save energy.

Some examples of electrical panels

A wide range of regulation systems, inverters, cut-phase controllers,

transformer controllers can be supplied in order to best regulate
the operation of the machine.

14
 Benefits of electronic regulation

Regulating the capacity of dry coolers is often done by starting and

stopping the fans in sequence. Instead, the use of an electronic
controller provides great energy savings thanks to the continuous
modulation of all the fans.

SILENCER - THE WHISPERER®

This compact silencer, designed and tested in the LU-VE Group

laboratories, dramatically reduces sound pressure level up to 5 dB(A).
This significant result has been confirmed by tests carried out by TÜV
SÜD of Munich (Germany).
Condensers and dry coolers with “THE WHISPERER®” provide the
following benefits:
• Energy savings up to 10%
• Reduction of sound pressure level at equal capacity
• Increase of capacity at equal sound pressure level
• Smaller unit footprint at equal capacity and sound pressure level
• Elimination of warm air recirculation.

19
 DRY and SPRAY®
For large capacity air cooled condensers and dry coolers.

After exhaustive research into increasing the spray system capacities,

the new "DRY and SPRAY®" range was created.
The extraordinary performance levels due to highly efficient water
nebulizzation mean that this product is an alternative to traditional
cooling towers with additional important advantages.

The “DRY and SPRAY®” products work as traditional dry units until
the ambient air temperature is low enough to maintain the cooling
capacity and the coolant temperature (or condensing pressure) at the
planned conditions (dry operation).
The temperature passage from dry to spray operation is a planning
choice and usually is about 20°C.
This innovative technology also enables, depending on the ambient
air wet bulb temperature, a coolant temperature equal to or lower
than the dry bulb temperature of ambient air with significant energy
advantages.
A sophisticated control system adjusts the speed of the fans and the
nebulised water capacity as required.

The use of “DRY and SPRAY®” liquid coolers and condensers instead of
traditional “evaporative cooling towers” and “evaporative condensers”
is characterized by the following important advantages:

• Water consumption in spray operation mode is limited to short

periods per year. For long periods of the year during DRY operation
mode no water is used
• There is no tray containing warm stagnant water under the coil,

Cogeneration, cooling reciprocating engines and gas turbines
CASE
This concerns applications where the maximization of the ratio of
capacity to the amount of occupied space plays a decisive role ,
especially in larger plants.

For this reason, LU-VE Group has developed the POWER range
with fan diameter of 1,250 mm, adapted for transportation by
container, having following features:

• Footprint reduction
• Shipping cost reduction (two machines can be shipped in the
same container)
• Low energy consumption.

FOR ORGANIC FLUIDS
(ORCs)

CASE
2 Recently, electrical energy production plants of limited capacity
(about 100kW-5MW) based on Organic Rankine Cycles
operating with organic fluids (siloxanes, HFCs) have become more
widespread. For this kind of plant, LU-VE Group can offer an air
cooled condenser and an internal recuperator coil.

25
 The special feature of air-cooled condensers for this use is the
combination of high capacity of heat transfer, reduced temperature
difference between ambient temperature and condensing
temperature, and limited energy consumption for the fan
ventilation.

26
 For this application, LU-VE Group has developed a product
equipped with low-consumption EC fans and a spray system can
also be fitted to keep the condensing temperature low even during
the hottest months of the year.

The two graphs below show the optimization for an ORC plant:
obviously, the optimum point may be found in a different
condition depending on the different design conditions. However,
the contribution of an optimized condenser to the efficiency of the
cycle appears to be very significant.

 Oil & Gas industry
and special ATEX versions

The oil and gas industry requires highly reliable products, involving
thermodynamic and mechanical design aspects and also great
attention to safety considerations.
LU-VE Group can completely comply with all the criteria, thanks
also to the ASME Certification Mark with “U” designator of official
approval on its machines.
One more aspect of great relevance is the use of tubes with reduced
diameter (normally 3/8” or ½”) which drastically reduces the internal
volume. In other words, the charge of hydrocarbons present inside the
heat exchangers.

For applications in explosion risk environments, LU-VE Group has
a specific range equipped with fans which comply with the ATEX
Directive 94/9/EC for zones 1 and 2. To guarantee its complete
adherence to the official regulations, the machine displays the
EX mark. Therefore, all the sheet metal parts are treated with a
special paint which conducts current, guaranteeing the absolute
equipotential of all the surfaces: as an alternative, the machines
can also be supplied with stainless steel casings.

29
 Cooling liquids in industrial processes

An area where LU-VE Group products find a natural position is in

the cooling of liquids produced in industrial processes, including
both the cooling of machines and also the modulation/dissipation
of excess heat. The most modern trends in plant design aim to
reach the lowest possible levels of heat to be rejected, so as to
minimize the entropic losses of the system. With this objective,
LU-VE Group can supply machines which can operate with very
small temperature differences – even negative, if equipped with
spray systems.

30
 Automotive industry

The car industry has to frequently update its production and testing
facilities, increasing their efficiency, reliability and environmental
compatibility. As a result of this urgent necessity, LU-VE Group has
become the privileged supplier to the most important European
car manufactures, especially concerning the plant serving
the climatic rooms dedicated to testing vehicles and related
components. The key to success has always been LU-VE Group’s
ability to offer technologically advanced solutions, capable of
guaranteeing the best ratio of performance to cost calculated over
the entire operating life of the plant. Below, some data relative to
the consumption of energy and water for a large-scale plant in this
sector.

 Waste treatment plants

In modern European cities, waste treatment is now considered as

an industry which is capable of transforming refuse materials into
new products or of extracting energy from their combustion, often
combined with a district heating system. This sector requires large-
capacity dry coolers which have to comply with severe official
standards and regulations in order to ensure maximum reliability
of the product over time. The LU-VE Group “V”-bank units with
either copper or stainless steel tubes are used in the most up-to-
date facilities throughout the Continent.

32
Chemical and pharmaceutical industry

The production of chemical compounds for the pharmaceutical

and cosmetics industries has special requirements for dry coolers
which respect the environment and at the same time guarantee
the very highest hygiene standards: the series of units fitted with
DRY and SPRAY® systems, unlike the common evaporative towers,
apart from not producing unsightly vapour plumes, has been
designed for this precise sector. Most importantly, the water is
not recirculated; there is no drain tray collecting the misted water
which once sprayed onto the fins (mainly) evaporates or descends
down the fins and drips onto the ground where it is disposed of as
rainwater.
In addition, the sprayed water is a carefully treated and purified
liquid; this therefore excludes any possibility of the formation of
deposits and biofilm – the typical zone where bacterial colonies
grow. Water droplets are not dragged out by the airflow which,
after passing through the heat transfer surfaces, is expelled into
the atmosphere by the fans. This is ensured by the correct balance
of airflow and misted water. It is also verified by sophisticated
experimental measurements.
In confirmation of its quality and safety, the “DRY and SPRAY®“
product has obtained the Certificate of Safety and Hygiene issued
by the prestigious Domatec laboratory in Germany.

33
 Die-cooling for the production of plastics

The equipment for the die-forming of plastics requires continuous

cooling of the dies themselves; this has to be maintained during
the entire working process at a constant temperature with a very
restricted tolerance range so that the life of the equipment and the
quality of the product is preserved as much as possible.
It is therefore necessary to be able to calculate the performance
and reliability of the heat exchangers used in the process with
great precision.
LU-VE Group, the leader for many years in research and methods
of calculation for finned heat exchangers, has developed very
accurate and reliable calculation algorithms, based on data taken
from intense experimentation carried out in the company laboratory
and in collaboration with prestigious academic institutions.

34
Manufacturing standards

The heat exchangers are designed and constructed in compliance with the
standards and regulations in force within the European Union listed here:

• Machinery Directive 2006/42/EC

• Pressure Equipment Directive (PED) 97/23/EC
• Electromagnetic Compatibility Directive (EMC) 2004/108/EC
• Low Voltage Directive (LVD) 2006/95/EC

It is also possible on request to have machines sized according to the standard

ASME VIII div. I, approved by ASME U stamp.

Performance
All products are guaranteed to provide the performance levels indicated in our
catalogues, and all standard ranges are certified by Eurovent.

The tests standards applied to the machines are:

ENV 327 for heat exchange capacity of air-cooled condensers

ENV 1048 for heat exchange capacity of dry coolers

EN 13487 for the measurement of sound power level of condensers and dry
