Enhancing efficiency for more sustainable district heating pipe networks

District heating systems rely on insulated underground thermal networks to distribute heat and cooling efficiently and safely across multiple buildings. Fueled by renewable sources, like solar power or biomass, they offer effective energy-efficient solutions to reduce fossil fuel dependency. Pre-insulated pipes serve as the technical cornerstone for district heating networks, as well as specialised applications like biogas-fueled cogeneration and industrial process pipelines. With the Global market for pre-insulated flexible pipes projected to double by 2030, we refined our portfolio to meet the distinct demands of various end markets, from residential to industrial. Whether that’s non-flexible pipes that connect energy sources to substations or flexible pipes linking substations to commercial or residential buildings, at Armacell, we ensure specifiers find their fit-for-purpose pre-insulated solutions to minimise remote energy loss.

Effectively lower total installation costs

The complexities of district heating infrastructure demand durable, cost-efficient, easy-to-install, energy saving solutions. Highly flexible, lightweight, pre-insulated PE-Xa pipes enable specifiers to easily navigate bends and obstacles without joints or pre-formed elements while reducing civil works’ complexity and installation times. By offering a wide variety of carrier pipe dimensions available as single or double versions in the same jacket pipe, we’re dedicated to minimising installation time and costs by reducing required system components and accessories. As such, our pre-insulated pipe systems and related accessories are designed to be fully compatible with virtually all major competing pipe systems, making them easy to use for the expansion of existing local and district heating networks as well as renovation purposes.

Achieve optimal thermal efficiency

Renovating and upgrading inadequate thermal insulation marks a crucial step on a journey towards energy-efficient infrastructures. However, meeting the latest energy efficiency requirements while managing local and district heating network operating costs can be a challenge. That’s why our closed-cell foam solutions are specifically designed to help specifiers meet an ever-changing landscape of specifications. Both our PEX- and PUR-based solutions are precisely tailored to district heating infrastructures. Providing an extensive range of insulation thicknesses, we’re committed to empowering the meticulous design of local and district networks, ensuring alignment with operating parameters, regulations, and grant requirements.

Rely on high quality and durability

Rely on high quality and durability

The insulation you choose must be durable to withstand wear and tear and achieve maximised lifetime performance. As a global leader in insulation materials, we deliver the highest quality and longevity, conducting more than 30,000 quality tests each year and optimising our materials every time you specify and use our solutions.

Lower your total cost of ownership

Lower your total cost of ownership

Insulation is essential to the operational reliability of mechanical systems and equipment. To avoid high maintenance, repair, and consequential costs, the technical performance and reliability of the installation must always be the deciding factor when selecting equipment insulation. Our comprehensive range of high-performing system solutions and products ensures long-term reliable results. By improving the performance and durability of the installed system, operators can benefit from optimal operating conditions and a longer service life, significantly reducing the total cost of ownership.
