Double pre-insulated pipe ECOFLEX Varia Twin 2x40x3.7/140, 6 bar, temp. 80°C, for central heating and chilled water installations, thermal insulation made of PE-X foam, corrugated outer jacket HDPE. /200m/ 1018240

Double pre-insulated pipe for central heating and cooling installations.

Uponor Ecoflex Varia Twin pipe is a reliable solution for heating and cooling systems, designed for efficiency and durability. Made of cross-linked polyethylene (PE-Xa) with a PE-X foam insulation layer, it provides minimal heat loss and corrosion resistance. The "Twin" construction combines the supply and return pipes in a single jacket, simplifying installation and reducing costs.

This pipe is ideal for both professional installers and end customers looking for a solid and efficient system. Thanks to its high flexibility, installation is quick and easy, even in difficult conditions. The use of PE-X foam provides not only excellent thermal insulation but also dampens the sound of the flowing medium.

Construction features and application

Ecoflex Varia pipes comply with PN-EN 15632, guaranteeing their high quality and safety. A wide range of operating temperatures – from short-term 90°C to continuous 80°C – allows them to be used in various heating systems. The maximum working pressure of 6 bar ensures safe operation for many years.

The corrugated outer jacket made of HDPE protects the pipe from mechanical damage and facilitates its laying in the ground or inside the building. This makes the pipe resistant to SLW 60 loads. It is worth mentioning the anti-diffusion barrier in the core pipe, which prevents oxygen from penetrating the installation, which is particularly important in closed systems.

Advantages for the installer and end user

• Fast installation: The high flexibility of the pipe allows for easy adaptation to existing infrastructure and reduces installation time.
• Durability: High-quality materials ensure a long system life and minimize the risk of failure.
• Energy efficiency: PE-X foam with a low thermal conductivity coefficient (0.04 W/(m.K)) reduces heat loss, lowering operating costs.
• Versatility: Can be used in heating and cooling systems and domestic hot water heating.
• Safety: Compliance with PN-EN 15632 standards guarantees safety and system reliability.
• Comfort: Dampening of the sound of the flowing medium ensures quiet operation of the heating/cooling system.
• Easy identification: Color-coded supply and return pipes facilitate correct installation and servicing.
• Minimum bending radius: 700 mm allows for flexible routing of pipes even in tight spaces.
