SOLAR HEATING FROM A-Z
Arcon-Sunmark is a part of the VKR Group which was founded by Villum Kann Rasmussen in Denmark in 1941. Today
VKR Holding’s companies employ about 13,500 people in more than 40 countries. VKR Holding owns companies that
bring daylight, fresh air and a better environment into people’s everyday lives, including the VELUX Group – and
Arcon-Sunmark.
Solar heating is the cleanest of all energy sources. At the
same time the energy from the sun is cheap and the costs
are stable over time. The most efficient way to harvest
the sun is with large-scale solar thermal installations.
Arcon-Sunmark has developed the world’s most advanced
and comprehensive solutions, tailor-made for large-scale
solar thermal installations. The company has installed the
largest solar heating plants in Europe – and even the
largest plant in the world. Our very first large project
(1988) is still working to perfection and providing clean
and cheap energy for citizens in the village Saltum,
Denmark. In total, we are behind more than 100
installations > 1,000 m2 and we keep on supplying the
market with the most efficient solar heating solutions.
Since 1974 Arcon-Sunmark has installed more than 1.1
million m2 solar collectors in a great variety of locations
and industries; district heating plants, breweries, mines
and in the greenhouse industry. Our collected data,
learnings and hands-on experience from all these projects
are turned into real benefits for the customers, who can
trust us to deliver individual, tailor-made, efficient and
reliable solutions.
Arcon-Sunmark is Danish and we stick to the best
Scandinavian traditions of always delivering the highest

YOU: WOULD LIKE CLEAN AND CHEAP HEATING
WE: DO THE REST
Besides giving light and life, the sun produces enormous amounts of
energy – and heat. The sun is the cleanest energy source as it emits
no CO2 and offers a lot of other benefits. It is cheap, it is clean and it
is lean. Danish Arcon-Sunmark provides the large-scale solar thermal
installations, which make it possible to harvest the sun, turning it into
stable and low heating costs and a greener image, while at the same
time reducing the use of fossil fuels.
It takes a lot more than effective collectors to establish a solar heating
plant. We are the experts, and we take care of all project stages. From
consideration, planning, decision making and approval, financing,
authority approval, groundwork and installation, to testing and
commissioning. Actually we never leave a project, but continue to
optimize the performance over its entire life cycle. At Arcon-Sunmark,
via our online monitoring tools, we constantly observe the performance
of every single installation via online supervision and are always able to
advice on how to avoid potential challenges and how to get the most of
harvesting the sun.

STEP 1: WE PREPARE AND PLAN FOR YOURSUCCESSThe right preparation and project planning is essential for success. Also when
it comes to solar heating. From the very first consideration, Arcon-Sunmark can
assist. We have the most experienced and skilled team, familiar with all sorts of
projects and details and ready to prepare and plan everything from A to Z.
INDIVIDUAL ENERGY ASSESSMENT AND PROJECT PLANNING: We always start with a detailed
process study of your existing plant and take every individual detail into account to ensure
seamless integration of the solar heating plant.
SAVINGS: How to optimize the performance and the savings? We do the math and calculate all details
prior to starting a project.
PLANT DESIGN: Solar heating for district heating or industrial processes? No matter the purpose, we develop
an individual plant design and carry out a timetable, which we stick to.

THE BEST FINANCING SOLUTIONWould you like the very best large-scale solar heating installation or simply the
clean energy? Before starting a project, of course the financing needs to be
in place. We act as partners and are able to advice in this matter and even to
take care of the financing.
DIRECT INVESTMENT: From experience we know the different and the best ways to finance a large solar heating installation,
and will be glad to share our knowledge with you and your financial advisors. On some markets you will have the opportunities
to get a subsidy. Arcon-Sunmark can help you navigate in the often complicated set of subsidy regulations.
PPA: With partners like the financially solid Danish VKR Holding, we can offer you to buy only the heating instead of the total
installation. The price will be fixed at a certain price per MWh, defined in a long-term service contract called a Power Purchase
Agreement (PPA).

STEP 3: WE TAKE CARE OF ALL SMALLDETAILS IN LARGE CONSTRUCTIONSWhen the project is planned and the financing is in place, the construction phase starts. Although
we think big and construct large-scale installations, we pay attention to all details.
PIPES: Long-term stability of the piping is of great importance for the overall performance. We only use
pipes of the highest quality and all pipes come insulated and with integrated alarm wires.
PIPES: We plan the entire field piping in detail and with our unique technology and proven concepts. The complete pipe solution
is prefabricated and quality tested prior to the installation. This saves installation time and money, and ensures the best possible
quality.
FOUNDATION: No matter how difficult and hilly the terrain may be, we know how to prepare the land for the optimal
installation of the collectors.
FOUNDATION: In collaboration with local specialists and partners, we make sure that the groundwork is
done to perfection.

HT-HEATBOOST
The HT-HEATstore collector offers
highly documented efficiency. It is
specially designed with Anti Reflex
(AR) coated glazing, a high-performance
laser welded selective absorber and
is additionally equipped with a special
FEP foil. We recommend the HT-
HEATstore collectors for installations
requiring high temperatures as e.g. in
the industry or for heat storage. HT-
HEATstore is a reliable and thoroughly
tested product available in different
versions, with different pipe dimensions
thus making it possible to optimize
the flow conditions for the specific
installation.
The HT-HEATboost collector offers a
high yield at a competitive price and is
a reliable and thoroughly tested product.
It is designed with Anti Reflex (AR)
coated glazing and a high-performance

CONTROL SYSTEMS: The control system is the brain of the installation and where it all comes together. That’s
why reliability is key. The Arcon-Sunmark control system is based on more than 25 years experience of designing,
constructing and controlling solar stations. All our control units are based on the Siemens PLC (S7), and they all
contain an IGSS SCADA system offering a harmonious and clear user interface that is available in English, German,
Spanish or Danish.
ELECTRICAL INSTALLATIONS: All wiring for the control unit on the heat exchanger unit is pre-fabricated. Merely the
power supply must be added to establish the connection from the control board to the temperature sensors and solar
radiation meters in the solar field. This connection is often made as a fibre cable.
SOLAR STATIONS: When delivered the solar station is pre-insulated, wired and tested, ready for start-up. The control
system enables live data exchange for performance optimization and alarm handling, and the station has an integrated
by-pass for heat discharge and anti-freeze protection, which allows for higher solar fractions and a lower glycol
percentage.

The first step in the process of establishing a seasonal storage that will
extend the use of the sun and make the solution even more profitable, is to
create a large pit and cover it with a welded liner.
SEASONAL STORAGE: We have the expertise to build/integrate seasonal storage to store excess heat for periods where the sun
delivers less energy. A huge thermal seasonal storage encapsulated by a welded liner allows the energy to be stored in water.
Finally the storage pit is covered with a layer of floating insulation.
Surplus energy from the sun or other heating sources is stored in hot water for it to be used for day to night variation, as well as
seasonal storage, from summer to winter, extending the use of the sun and making the solutions even more profitable.

STEP 4: WE INSTALL,SO YOU CAN HARVEST AND STORE THE ENERGY
And you harvest the sun with the most advanced and efficient solar collectors,
but the next step in the process is not less important. From our extensive
research and daily operational experiences we have the technological know-
how to turn the collected solar radiation into heat in a way that optimizes the
performance. When different sources of energy are used, we know how to
integrate and create synergies.
LEAN PIPING:
Piping is an important part of a
large-scale solar heating installation.
Arcon-Sunmark uses a unique
method, where complete pipe
systems are prefabricated at our
own factories prior to installation.
This leads to higher quality and
shorter installation time.
PUMP INSTALLATION:
The heat absorbed by the solar
collectors is led into the solar
station. The solar station includes
pumps, heat exchanger, control
valves and necessary service
valves for easy maintenance.
ELECTRICAL INSTALLATION:
We use the latest technology, based
on SCADA systems and industrial
PLC hardware, to optimize the plant
performance and durability.

Operational excellence and optimization are extremely important to get the
most out of the harvested sun. Arcon-Sunmark will follow up and perform
service checks including onsite inspections to ensure optimum system
operation. With remote access 24/7 we are always on top of the situation
for every individual installation and can assist in optimizing the performance.
No company is more dedicated to quality assurance than us, and thanks
to our experiences from the many different implementations we have
been responsible for, we have the in-depth knowledge on how to optimize
operational performance. We collect and combine all data and use the
information for an ongoing fine-tuning of the operations. We also offer
individual tailor-made service contracts.
STEP 5: WE OPTIMIZE OPERATIONS – AND NO PROJECT IS LEFT BEHIND
OPERATION OPTIMIZATION: A powerful solar heating software and a logical user interface make it easy
to control and optimize operations.
