Double pre-insulated pipe DELTA PEX HEAT DUO 25+25x125, PN6, for central heating installations, thermal insulation with PE foam, corrugated HDPE outer jacket 70612502500W

Insulated double pipe for efficient heating installations

DELTA PEX HEAT DUO 25+25x125 insulated pipe is a comprehensive solution for building efficient and energy-saving central heating installations and domestic hot and cold water distribution systems. The two-pipe construction, with conductive pipes with a diameter of 25 mm and insulation with a thickness of 125 mm, minimizes heat loss and ensures a stable medium temperature. Manufactured in accordance with PN-EN 15632-1 and 3 standards, this pipe guarantees safety and reliable operation for a long time.

Construction and properties for professionals and users

The pipe consists of two PEX (cross-linked polyethylene) pipes intended for medium transport and a layer of polyethylene foam (PE) insulation, which effectively reduces heat loss. The whole is surrounded by a corrugated outer jacket made of high-density polyethylene (HDPE), providing mechanical protection and resistance to damage during installation and operation. The corrugated surface facilitates laying the pipe in difficult terrain conditions and also compensates for thermal movements of the installation.

• High flexibility: Allows easy routing of the pipe in complex routes, bypassing obstacles and reducing the number of fittings – this translates into saving time and installation costs.
• Low bending radius: Allows the pipe to be adapted to the specifics of the installation without the need for additional elements.
• Excellent insulation: PE foam with a low thermal conductivity coefficient minimizes energy losses, which translates into lower heating costs and environmentally friendly operation of the system.
• Mechanical resistance: Durable HDPE jacket protects the pipe from damage during transport, installation and use in difficult external conditions.
• Universality of application: The pipe is suitable for central heating installations, domestic hot and cold water distribution, and floor systems.
• Temperature resistance: The possibility of use in systems with a temperature of up to 95°C allows cooperation with various heat sources.
