Double pre-insulated pipe AustroPEX WPP A145-2x32 PEX, for monoblock heat pumps, thermal insulation with PE foam, corrugated outer jacket HDPE PIP-XCH-145D32

Pre-insulated pipe for heat pump and central heating installations

This AustroPEX WPP A145-2x32 PEX twin-pipe pre-insulated pipe is a comprehensive solution for efficient and energy-saving central heating installations, especially in monoblock heat pump systems. The design with two pipe conductors (supply and return) and two empty ducts facilitates installation and allows for aesthetically pleasing routing of control and power cables for the heat pump. This combination of functionality and convenience is appreciated by both installers and end-users.

Construction and application

The pipe consists of several key elements that provide its unique properties. The inner pipes are made of cross-linked PE-Xa (SDR 11), guaranteeing high corrosion resistance and long-term reliability. The EVOH anti-diffusion barrier protects against oxygen penetration into the installation, and the insulation made of closed-cell microcellular PE foam minimizes heat loss – water absorption is below 1% (according to DIN 53428). The whole is surrounded by a corrugated outer jacket made of HDPE, which provides mechanical protection and facilitates unwinding and laying the pipe.

The AustroPEX WPP A145-2x32 PEX pipe is primarily used in:

• Central heating installations in residential and commercial buildings.
• Systems with monoblock heat pumps – ducts allow for convenient routing of control and power cables.
• District heating networks.
• Domestic water installations (depending on the pipe version).
• Underfloor heating systems.

Advantages for professionals and users

• Fast installation: The pre-insulated construction eliminates the need for additional pipe insulation, reducing installation time and labor costs.
• High energy efficiency: Minimal heat loss translates to lower heating bills and a reduced environmental impact.
• Flexibility and ease of installation: The corrugated outer jacket makes it easy to route pipes in difficult conditions, even in tight spaces.
• Durability and reliability: High-quality materials guarantee a long service life of the installation without frequent repairs or replacements.
• Versatility: The ability to use it in various types of installations – from central heating to heat pumps – makes it a universal solution.
• Cable ducts: Two empty ducts simplify the routing of heat pump control cables, increasing the aesthetic appeal of the installation.
• Corrosion resistance: PE-Xa pipes are corrosion resistant, ensuring the long-term reliability of the heating system.

Thanks to the combination of these features, the AustroPEX WPP A145-2x32 PEX pre-insulated pipe is an investment in comfort, savings and peace of mind for both installers and end-users.
