Calpak History
1975
Calpak BP is established in Greece as a subsidiary of British Petroleum, with the aim of making solar energy sustainable and accessible to all.
1977
The production of Calpak Neo, the first solar water heater system with a horizontal closed circuit tank, begins. It is the starting point of a story full of technological innovations.
1979
A state-of-the-art solar laboratory is being created at Calpak’s facilities, the first of its kind in the entire European industry. Its purpose is to facilitate the precision measurements necessary for the further development of solar technology.
1981
Calpak Mark2 enters the production line. This thermosiphonic system is a huge commercial success, helping to change the perception of solar thermal energy across Europe.
1985
Calpak is now developing into a European leader in large-scale solar thermal installations as well, mainly covering the hot water needs of hotels through integrated high-tech solutions.
1989
Calpak becomes independent from BP and continues its highly successful course as a purely Greek company
1993
Calpak acquires an export profile, taking part in almost all major international exhibitions of the heating industry. For the first time that year, its exports account for more than 50% of its total turnover.
1998
With the aim of optimal quality and increasing production capacity, a large investment plan is being implemented to expand the Company’s factory and renew its mechanical equipment.
2002
Calpak launches high-tech production of vacuum collectors.
2003
The Company starts the production of selective collectors with laser technology bonding.
2004
Calpak completes the first combined installation of solar systems for space heating and hot water.
2005
Calpak is recognized as one of the top 10 companies in Europe that certify their collectors with the SolarKeymark quality mark.
2007
Calpak’s exports have expanded to all 5 Continents.
2008
The production of CL, a complete line of high-quality floor-standing hot water tanks, with a capacity of up to 9000 liters, begins.
2010
Calpak enters into long-term agreements with the National Scientific Research Center “Demokritos”, the University of Patras, the Technical University of Athens, the Center for Renewable Energy Sources and other scientific and technological bodies. These agreements significantly strengthen the capabilities of the Company’s Research & Development sector.
2013
Significant investments are made towards the technological improvement of the productions means of Calpak. Robotic technology is now widely used in our factory enabling unprecedented precision in the welding processes and increasing a lot the maximum capacity our production.
2014
Significant investments are being made for the technological improvement of Calpak’s means of production. Robotic technology is now widely used in the factory, ensuring unprecedented precision in the welding process and significantly increasing the production rate.
2017
Calpak R&D laboratories present a new class of fresh water tanks. The high-performance X-Flow technology allows the storage and transfer of thermal energy with 99% efficiency, thus offering endless hot water providing savings!
2019
The doors of Calpak’s new factory open, marking a new era of design and production of quality solar systems, through the most technologically advanced and intelligent robotic machines.
2021
The production of Prisma begins. It is a truly innovative collector that stands out for the use of innovative materials in its construction, as well as its fully automated production platform.
2022
With Mark5 comes Calpak’s new flagship, which places the strength, robustness and design of solar water heaters on another level.
