Double pre-insulated pipe ECOFLEX Aqua Twin 25x3.5-20x2.8/140, 10 bar, temp. 70°C, for DHW installations, thermal insulation made of PE-X foam, corrugated HDPE outer jacket 1084885

Double pre-insulated pipe for efficient hot water transfer

Uponor Ecoflex Aqua Twin pre-insulated pipe is a comprehensive solution for hygienic and energy-efficient domestic hot water transport, especially in underground networks. The design with two pipes in one jacket allows for flexible use – both for supplying and circulating hot water, or even simultaneously transferring hot and cold water. This is an ideal solution for residential and commercial construction where reliability, user comfort and minimizing energy losses are important.

Construction and properties

The pipe consists of several key elements, providing its unique properties: an inner pipe made of cross-linked polyethylene (PE-Xa), characterized by high resistance to temperature and pressure; an insulating layer of closed-cell PE-X foam, effectively reducing heat loss (thermal conductivity coefficient at 0.04 W/(m.K)); and a corrugated protective pipe made of polyethylene (HDPE), providing mechanical protection and compensation for thermal expansion. This combination makes the pipe flexible, easy to install and resistant to damage.

Application and benefits

The Ecoflex Aqua Twin pipe is perfect for DHW installations, meeting the PN-EN 15875 standard for the design temperature of the supply water of 70°C (short-term up to 80°C). Its flexibility makes it easy to lay in difficult conditions, and the self-compensating construction minimizes thermal stresses. Additionally:

• Hygiene: Materials used in production guarantee the purity and safety of the medium transported.
• Energy saving: Effective thermal insulation minimizes heat loss, reducing operating costs.
• Durability: High quality materials and certificates (VDI/KIWA, EN15632, ISO 9001/14001) confirm the long service life of the system.
• Resistance: The pipe is resistant to SLW 60 loads, allowing its use in places exposed to vehicle traffic.
• Quick installation: The flexibility of the pipe and the possibility of using Uponor Wipex connection technology (without the need for welding) speed up installation work.
• Versatility: The ability to run two independent pipes in one jacket increases the functionality of the system.

Uponor Ecoflex Aqua Twin 25x3.5-20x2.8/140 pre-insulated pipe with a maximum working pressure of 10 bar is an investment in comfort, safety and energy saving in every building. The minimum bending radius is 650 mm, which facilitates installation even in tight spaces.
