Eco-Flex metal hoses with foam rubber thermal insulation are a reliable, flexible and durable solution for connecting collector groups of solar systems to heating equipment.
They provide efficient heat transfer, protection from external influences and ease of installation in both external and internal systems.
Types of metal hoses in insulation
We produce metal hoses for connecting solar collectors of two types:
- S1 – single insulated metal hose. Used to connect individual circuits or devices.
- S2 – double insulated metal hose. Used for simultaneous connection of direct and return pipelines, can be equipped with an electric silicone cable for temperature control.
Advantages of Eco-Flex metal hoses for solar systems
- Light weight and economical. Stainless steel metal hose is much lighter and cheaper than copper pipelines, which simplifies installation and reduces installation costs.
- Reliable thermal insulation. Double-layer foam rubber insulation effectively protects the metal hose from:
- atmospheric precipitation,
- ultraviolet light,
- temperature changes,
- mechanical damage,
- the influence of oils and fats.
- Operational safety. In double models, the electric silicone cable is placed in such a way as not to contact the walls of the metal hose, which guarantees the reliability and durability of the system.
- Ease of installation. Connection is made using the Profi metal hose installation system, without the need for complex welding or special equipment.
Application
- Connection of solar collectors and heat pumps to heat exchangers, accumulator tanks and boilers.
- Use in hot water supply and heating systems operating with solar systems.
- Installation in private houses, cottages, industrial and commercial facilities.
Eco-Flex metal hoses for solar systems are an effective, safe and modern solution for solar heating systems, combining energy efficiency, ease of installation and durability.
