Pre-insulated pipes – comprehensive solutions for efficient installations

The ECOFLEX Quattro quadruple pre-insulated pipe is an advanced solution dedicated to building efficient and reliable heating networks and domestic hot and cold water installations. The “all-in-one” construction combines four pipes, enabling simultaneous transport of the heating medium and circulating hot water, which significantly simplifies installation and reduces investment costs. This is an ideal solution for both extensive networks and single building connections.

The pipe is characterized by high flexibility, which facilitates laying even in difficult terrain conditions. Made of cross-linked polyethylene (PE-Xa) with an anti-diffusion barrier, it ensures durability and corrosion resistance. Insulation made of closed-cell PE-X foam minimizes heat loss, and the corrugated outer jacket made of HDPE protects against mechanical damage and weather conditions. Thanks to this, the ECOFLEX Quattro system guarantees energy efficiency and long-term use.

Application and key features:

• Versatility: Ideal for transporting heat, domestic hot water and cooling water in underground networks.
• Energy efficiency: PE-X foam with a low thermal conductivity coefficient (0.04 W/(m.K)) minimizes energy losses during medium transport.
• Durability: The use of high-quality materials, such as PE-Xa and HDPE, ensures corrosion resistance and long system life.
• Easy installation: The flexible construction makes it easy to lay the pipes, and the connection system does not require specialized tools or welding.
• Safety: The pipes meet European standards EN 15632 and ISO 15875, guaranteeing safe use.
• Load resistance: Adapted to SLW 60 loads, allowing them to be used in places exposed to vehicle traffic.

The ECOFLEX Quattro pipe is designed to operate at a temperature of up to 80°C for central heating and 95°C (short-term) / 70°C (continuous) for domestic hot water at a maximum working pressure of 6 bar and 10 bar, respectively. Color-coded insulation around individual pipes makes it easier to identify the medium flowing inside them during installation and operation. This system is a comprehensive solution for modern heating and sanitary installations, combining functionality, economy and reliability.
