Very low heat loss and high durability – because we use pressure-injected PUR foam which is fully bonded to the pipe and the casing.
CALPEX® is a flexible, self-compensating, continuous and heat-insulated pipe system with a medium pipe made of cross-linked polyethylene.
CALPEX® district heating pipes can be supplied in rings of up to 807 m in one piece, depending on the dimensions. This largely eliminates underground connection points.
CALPEX® district heating pipes only need 60% of the line width required for plastic casing pipes in the past.
CALPEX® district heating pipe is so flexible that it can easily be adapted to virtually any pipeline conditions. Pipes can pass below or above existing supply lines.
The composite system prevents thermal expansion of the medium pipe. No compensating measures (expansion zones) are required underground.
The insulation consists of pentane-blown polyurethane foam (PUR). The excellent lambda value of 0.0199 W/mK achieves exceptional insulation values with a small volume.
In the CALPEX® system, the inner pipe forms a composite together with the insulating foam. In case of pipe damage due to external influences, this means that no cavities are created where water could collect and flow toward the building.
Heat supply pipes, drinking water transportation, drainage/waste water systems, cooling plants, swimming bath technology and agricultural applications are just a few examples from our extensive list of references.
This brass connector is compressed onto the pipe with a special tool. Available with external thread, as a pipe coupling, T-joint or in steel with a weld end.
Simple screwed connector that does not require a special tool.
Available with external thread, as a pipe coupling, T-joint or in steel with a weld end.
The FUSAPEX® electro-welding joint in crosslinked polyethylene (PEX) is used to make fast, simple and reliable joints for CALPEX® medium pipes with operating temperatures from -40 to +95°C
Our new CALPEX® Clip T-I-L Shell marks a new departure in protection for pipe junctions in low-temperature systems. Instead of wasting time screwing the connection in confined spaces, the new click-on connector makes child’s play of the job!
16 sealing clamps quickly make child’s play of installing the T-I-L Shells – the perfect protection for pipe junctions.
The new T-I-L Shells are filled on site with fine-pore dual-component insulating foam to keep the pipe junction absolutely tight.
