Are you looking for a reliable solution for maintaining temperatures over long distances? Then POLYMELT’s pre-insulated PP-R and PP-RCT pipes are just what you need. Designed for underground installation, these pre-insulated pipes offer numerous advantages for various applications, ensuring energy efficiency and cost-effectiveness.
Advantages of pre-insulated pipes
- Energy savings: Our pre-insulated pipes are insulated with rigid PUR foam and encased in a protective casing, minimizing energy losses during transport. Whether for hot water, drinking water, heating, or cooling water, these pipes ensure efficient temperature maintenance over long distances, making them real energy savers.
- Low thermal conductivity: With a very low thermal conductivity of approximately 0.024 to 0.035 W/mK, our pre-insulated pipes effectively reduce heat transfer, resulting in minimal temperature fluctuations along the pipe.
- Corrosion resistance: Thanks to their construction, our pre-insulated pipes are resistant to deposits and corrosion, eliminating the need for corrosion additives and keeping maintenance costs low over their entire service life.
- Easy installation: Our pre-insulated pipes are lightweight and easy to connect, minimizing installation time and labor costs. Their suitability for both new construction and retrofits makes them a versatile choice for a variety of projects.
- Versatile applications: Our pre-insulated pipes are suitable for a wide range of applications, including hot and cold water, district heating and cooling, and thermal water systems. Whether for residential, commercial, or industrial use, these pipes offer reliable performance and energy efficiency.
Pre-insulated PP-R and PP-RCT pipes from POLYMELT: ideal for various applications:
- Hot and cold drinking water: Ensuring an efficient and reliable drinking water supply in residential, commercial, and industrial areas.
- District heating and cooling: Optimize the efficiency of district heating and cooling systems with our pre-insulated pipes to reduce energy losses and operating costs.
- Thermal water systems: Transport thermal water over long distances with minimal energy losses, making our pre-insulated pipes the ideal choice for thermal water systems.
Technical specifications:
- Insulation: Polyurethane foam with a density of approximately 80 kg/m³ and a thermal conductivity of 0.024 W/mK.
- Pipe: Made of PP-R or PP-RCT from the ECOSAN or MECHANICAL product lines.
- Jacket: Polyethylene (HDPE) jacket provides additional protection and durability for the insulation.
