Polarpipe^® – insulated and frost-protected pipe system

Intended for installations where you cannot dig in frost-free ground.

Extena Polarrör isolerat och frysskyddat rör med värmekabel

Extena offers two types of insulated pipes. One is Polarpipe^®, which is a complete frost-protected pipe system consisting of one or two standard pipes made of PE100 RC (one for water and one for sewage), a self-limiting heating cable, a layer of heat reflective aluminium, closed cell heat insulating foam and a durable polyethylene outer sheath. This design eliminates the need to dig or blast down to a frost-free depth – the pipe can be laid on the ground or on snow and ice if desired, with minimal covering. The result is frost-proof water and sewage with no or very little interference with nature.

Our other insulated pipe system has a similar design to Polarpipe^®, but without the heating cable and heat reflective aluminium.Polarpipe^®
Frost-proof water and sewage for coastal areas, mountain regions and temporary modules. As more houses and cabins are built on the coast and in mountain regions, the need for energy efficient and environmentally friendly water and sewage systems is increasing. In these areas, where it is often difficult to lay pipes at a frost-proof depth without seriously harming the sensitive local environment, innovative solutions are required.

Developed for this type of environment, Extena Polarpipe^® provide a fast, frost-free water supply whatever the season and ground conditions. The system consists of a water pipe (media pipe) with a self-limiting heating cable to prevent the water from freezing.

This innovative design eliminates the need to go down to a frost-free depth – the pipe can be laid on the ground or on snow and ice if desired.

Examples of applications for Polarpipe^®

Mountain regions and coastal areas
Are you going to build a new house in the mountains or do you already have a cabin on the coast? Polarpipe^® pipes allow you to easily transfer water and sewage in mountainous environments without having to carry out costly blasting and excavation that impacts nature. Lay the pipe at a shallow depth or directly on the ground.

Construction sites and temporary modules
Polarpipe^® is a perfect alternative for temporary water and sewage solutions, such as on construction sites or portakabins for schools or offices. The piping system is easy to lay and connect, and thanks to the heating cable and the system’s high-quality insulation, water and sewage demand can be ensured cost-effectively at temperatures down to minus 30 degrees depending on wind and covering.

Marine applications
Large ships and boats that call in to large ports often need to connect to a water and sewage system. Polarpipe® pipes are particularly suitable for this purpose. The flexible and durable design of the piping system means that it can easily be routed to ships and can withstand the harsh marine environment.

Insulated pipe without the heating cable
Our other insulated pipe system has a similar design to Polarpipe^®, but without the heating cable and heat reflective aluminium. The system consists of a standard pipe made of PE100 RC fitted with closed cell heat insulating foam and a durable polyethylene outer sheath. This pipe is very suitable for heat pump installations, for example.
