BRUGG - Model CALPEX PUR-KING -Pre-insulated,Flexible Pipe
Our CALPEX PUR-KING pre-insulated,flexible pipe is the world champion in terms of energy efficiency its patented insulation material has a thermal conductivity of only λ 0.0199 W/mK, thereby surpassing a magical threshold.
This flexible and self-compensating pipe system is suitable for low-temperature applications and for use in local and district heating networks. The CALPEX pipe is an insulated underground pipe made from resistant materials that are optimally designed for a long service life in soil – the carrier pipe is made of PEXa and boasts excellent thermal and mechanical properties. The outer jacket is made from LLD-PE. The insulation material is polyurethane (PUR foam) with a thermal conductivity of just 0.0199 watts per metre and Kelvin – at an average measured temperature of 122 °F.
In this substance class, this is an undisputed record that is unrivalled by any comparable pipe system. That’s why our flexible CALPEX PUR-KING solution is also a patented conduit – we manufacture it in a continuously operating production process. The uniformly high quality of the insulation is verified and confirmed through regular measurements by an accredited testing institute.
Prior to the successful development of the CALPEX PUR-KING pipe, a thermal conductivity of 0.0210 W/mK was generally considered a lower limit that was difficult to undershoot with reasonable technical effort. Against this backdrop, the CALPEX PUR-KING’s innovative production process is an even more remarkable achievement. The unique foam technology significantly increases the energy efficiency of these pre-insulated pipes.
Over the past ten years, BRUGG Pipes has managed to consistently reduce the lambda value of our CALPEX pipe systems through intensive research and development.
Thanks to our advanced CALPEX PUR-KING process technology, we have now succeeded in reducing the thermal conductivity of our CALPEX pipes to the world’s lowest lambda value of just 0.0199 W/m*K. With this record-low value, we have yet again managed to undershoot the established minimum thermal conductivity values for polyurethane. CALPEX PUR-KING is therefore an opportunity to substantially boost the energy efficiency of pre-insulated heating systems, leading to potential annual cost savings of up to 15%.
In addition to significantly reducing your operating costs, our pre-insulated heating pipes also allow substantial savings on insulation materials, thanks to the innovative construction of the product. This, in turn, has a positive impact on your excavation and transportation costs. As a general rule, the thickness of the insulation material is optimised in line with the standard pipe diameters and joint types.
