We pay particular attention to renewable energy sector, which represents the future of global power generation. Our excellent heat pipe solar collectors highlight our core values and philosophy. CSM TUBE constantly invests in equipment, research and skills for renewable energy sector.
For example, we can manufacture all kinds of coiled tubes for heat exchange to equip solar heating systems. We also produce collectors for heating coils, as well as headers and connections to create heating networks for domestic and commercial use.
In our production line, heat pipe solar collectors are manufactured according to the highest international standards. The renewable energy sector requires products which can resist corrosion and last for a long time, characteristics that are perfectly represented in our connectors, headers and coils. They will become a reliable part of the sustainable energy strategy of any organization.
Our stainless-steel tubes for solar collectors are available in coiled and bar formats with different thickness and diameter. High nickel and AISI alloys can be used along with heat treatment to ensure extra durability.
