Pre-insulated CALPEX QUADRIGA pipe – a comprehensive solution for your installation

The CALPEX QUADRIGA pre-insulated pipe is an advanced solution for building efficient and reliable heating and sanitary networks. The quadruple pipe design (2x sanitary + 2x heating) allows for simultaneous transport of hot and cold domestic water and heating agent in one route, which significantly simplifies installation and reduces investment costs. It is ideal for both new buildings and for the modernization of existing installations.

Construction and properties

The pipe consists of several key elements, ensuring its high quality and durability:

• PEX-a conductive pipes: Made of cross-linked polyethylene PEX-a with an EVOH anti-diffusion layer, they guarantee resistance to high temperatures (up to 95°C momentarily, continuous operation up to 90°C) and working pressure up to 10 bar.
• PUR foam insulation: Freon-free polyurethane foam with high density minimizes heat loss, ensuring energy efficiency of the installation.
• Outer LLDPE jacket: Durable, corrugated jacket made of low-density polyethylene protects the pipe against mechanical damage, moisture and UV radiation. The corrugated surface increases the flexibility of the pipe, making installation easier even in difficult conditions.

Applications and benefits

The CALPEX QUADRIGA pipe is used in:

• Heating networks: Supplying heat to residential, commercial and industrial buildings.
• Hot and cold domestic water installations: Providing comfort in every home.
• Heat pump systems: Efficient transport of the working fluid in renewable energy systems.
• Modernization of existing installations: Quick and easy replacement of old pipes without the need to excavate large areas.

Choosing CALPEX QUADRIGA gives you:

• Time and cost savings: Installation of one pipe instead of several separate lines.
• Energy efficiency: Minimal heat loss thanks to high-quality PUR insulation.
• Durability and reliability: Resistance to high temperatures, pressure and aggressive media.
• Easy installation: Flexible design makes it easy to lay pipes even in tight spaces.
• Versatility: Can be used in various types of heating and sanitary installations.

This specific pipe with a diameter of 142 mm (32+32)+(25+20) mm is ideal for larger installations requiring high throughput. Remember that the DN dimension refers to the nominal diameter of the inner pipe, and "d" denotes the outer diameter of the pre-insulated pipe including the PUR insulation and protective jacket.
