Magic threshold exceeded. CALPEX PUR-KING - The real KING with CROWN.

CALPEX PUR-KING boasts thermal insulation record with lowest-ever lambda value of 0.0199 W/m*K.

- The lambda value of 0.0199 W/m*K as atrustworthy average of many individual from several production lots
- Test results from independent and accredited institutes confirm the stated heat losses
- On the market since 2018, Pioneering work, patent granted
- Efficient insulation performance
- Flexible pipe laying thanks to small bending radius and low physical effort

The CALPEX PUR-KING is a patented flexible, continuous and self-compensating low-temperature pipe system boasting the world’s best lambda value of 0.0199 W/m*K. This exceptionally low value is proved and confirmed on an annual basis by an accredited test institute.

This record-breaking figure has made it possible to beat the what were previously thought to be the lowest physical thermoconductivity values for polyurethane by a significant amount. CALPEX PUR-KING is therefore becoming the trigger for another major increase in the energy efficiency of pre-insulated pipe systems for the heating and cooling market.

Why opt for a CALPEX PUR-KING pipe system?

  • Efficient

    Over the past decade, BRUGG Pipes has been able to decrease the lambda value for the CALPEX pipe systems further and further through intensive research and development work.

    With the newly developed CALPEX PUR-KING process technology, we have now succeeded in reducing the thermoconductivity of CALPEX pipes to the world’s lowest lambda value of 0.0199 W/m*K.

    With this record-breaking figure, we have been able to beat the what were previously thought to be the lowest physical thermoconductivity values for polyurethane by a significant amount. CALPEX PUR-KING is therefore becoming the trigger for another major increase in the energy efficiency of pre-insulated pipe systems for the heating and cooling market.

  • Flexible

    So that you can realise tight bending radii without any problems. Flexible installation thanks to small bending radii and less effort. Tighter winding radii mean lower costs due to longer delivery lengths in transport, storage and in the trench.


  • Reliable

    To give you peace of mind. Prepare for tomorrow today. The very best quality delivered. Reliable, long-lasting product solutions.


  • Fast

    So that you can keep to ambitious schedules without any stress. Product solutions delivered quickly for customers. Less laying work thanks to long delivery lengths and our sophisticated installation system. Patented clip cover and simple, reliable connections that do not require tools.


  • Expert

    Advice, experience and innovation included. Innovation, long-standing experience and needs-based, individual advice.


  • Victorious again

    CALPEX PUR-KING wins DTI test for fourth time in a row
    Every year, the Danish Technological Institute carries out an extensive series of tests on pre-insulated district heating pipes.  We are delighted to announce that, for the fourth time in a row, we came top in the flexible PEX pipe system category with our CALPEX PUR-KING. In the 4 years since it was launched on the market, we have not only emerged as the test winner but have also been the only manufacturer with consistently low values.

    Forget Covadis – there’s no beating CALPEX PUR-KING!
    Boasting the world’s best insulation value, CALPEX PUR-KING – with its patented PUR foam and exceptionally high Swiss quality standards – simply cannot be beaten.

    Thanks to the closed-cell PUR foam, the heat loss remains almost as low as on day one – without a diffusion barrier. The extremely efficient insulating performance enables annual energy savings of up to 15% and will also help you to reduce CO2! The true king wears a crown.
