Double pre-insulated pipe for efficient heat and cooling distribution

Uponor Ecoflex VIP Thermo Twin pipe is an advanced solution for building heating and cooling networks, as well as distributing hot and cold water. It utilizes unique vacuum insulation (VIP) technology in combination with flexible PE-X foam, providing exceptionally low heat loss – up to 60% less compared to traditional systems. The "Twin" construction – two pipes in one protective jacket – simplifies installation and reduces installation costs. It is an ideal solution for both professional installers and end customers looking for energy-efficient and durable systems.

Construction and properties

The pipe consists of several key elements that ensure its high performance and reliability:

• Conduit pipe: Made of cross-linked polyethylene (PE-Xa) with a diameter of 25 mm and a wall thickness of 2.3 mm, it is characterized by high resistance to temperature, pressure and corrosion. It has an EVOH anti-diffusion barrier that prevents oxygen from entering the installation.
• Insulation: Vacuum insulation panel (VIP) with a thermal conductivity coefficient of λ₅₀ = 0.004 W/(m·K) and closed-cell PE-X foam provide excellent thermal insulation.
• Protective pipe: A durable and flexible jacket made of polyethylene (HDPE) in black color protects the inner pipes from mechanical damage and weather conditions. The corrugated surface makes it easier to lay the pipe in the ground.
• Anti-diffusion zone: Additional protection against oxygen penetration into the installation, which extends its lifespan.

Application and benefits

The Ecoflex VIP Thermo Twin pipe is perfect for:

• Transporting heating and cooling water in underground networks.
• Central heating and cooling installations in buildings.
• District heating networks.
• Connections between buildings or in local distribution networks.

Why choose Ecoflex VIP Thermo Twin?

• Unmatched energy efficiency: Low thermal conductivity minimizes heat loss, reducing system operating costs.
• Fast installation: The flexible construction allows for easy laying of the pipe, reducing installation time by up to 20%.
• Durability and reliability: High-quality materials guarantee a long service life of the installation, resistant to corrosion and mechanical damage.
• Versatility: Can be used in various heating and cooling systems and for transporting domestic hot and cold water.
• Compliance with standards: The pipes are manufactured in accordance with PN-EN 15632 and EN 17414 standards, ensuring their safety and quality.
• Load resistance: Adapted to SLW 60 loads, ensuring safety in the event of vehicle traffic above the pipe.
• Minimum bending radius: 400 mm facilitates installation in tight spaces.

Uponor Ecoflex VIP Thermo Twin pipe is an investment in the future – an energy-efficient, durable and comfortable heating or cooling installation.
