We offer tailor-made solutions depending on application fields demands

The need

All cabling, both in residences and business premises, that is used to transfer energy and provide supply to electric devices creates so-called low-frequency magnetic fields, as well as electric fields, that remain even after the devices have been inactivated.

These fields depend on the voltage and intensity of the electric current and become weaker as the distance from their source increases. However, they are not negligible at distances up to one metre.

In particular, the field created when we come into contact with a device or when we are standing next to a plasterboard wall with electrical cabling behind it can be very strong.

The research

The design of a new multi-layer plastic conduit using anti – electromagnetic technology which will isolate inside the conduit a part of the radiation generated by the cables, preventing it from reaching the interior of the building.

The production technology

The development of a ground-breaking polymer of a special composition, where metal elements of low particle size are added to the interior layer of the new plastic conduits, thus shielding part of the electromagnetic radiation generated by the electrical cables.

The interior of the conduit functions as a shield against these fields, while its exterior protects the internal cables, in accordance with the requirements of European standard EN 61386-22.

Moreover, the metal content of the interior layer does not prevent the normal recyclability of the product, ensuring its very low environmental profile.

The creation

A new three-layer plastic conduit named SUPERFLEX® PLUS, available in diameters of Ø16, Ø20, Ø25, Ø32, and suitable for concealed type installations in plasterboard, in indoor spaces such as office buildings, hotel rooms and residences.

Antimicrobial technology

Antimicrobial protection reduces the risk of multiplication of the microbes found into the building materials, when is incorporated on their surface, and can be beneficial in keeping the numbers of microbes relatively low in between episodes of cleaning, providing better hygiene conditions.

KOUVIDIS has designed plastic conduit systems with antimicrobial technology exclusively to cover sensitive areas where hygiene is top priority.

The antimicrobial technology incorporated in KOUVIDIS conduit systems can ensure a reduction of up to 99% of the most dangerous pathogenic microbes (MRSA, E-coli) within 24 hours

Plastic conduit systems with antimicrobial technology

Innovation is a part of KOUVIDIS culture since its founder developed the first plastic pipes in 1979 with extra ordinary features that exceeded the steel pipes of that era.

Need

The protection of hygiene and the reduction of biological risks due to the growth and multiplication of pathogenic microbes in sanitary areas.

Research

Designing a conduit system that will be full in compliance with the specifications for cable management and protection, incorporating antimicrobial technology which will neutralize the pathogenic bacteria reducing the danger of contamination.

Manufacturing technology

The antimicrobial technology is incorporated in the raw material of the product during the manufacturing process to ensure continuous, lifelong, antimicrobial protection and reduction of up to 99% of pathogenic microbes, while at the same time it will not affect the mechanical properties of the conduit system.

Generation

Two integrated conduit systems, MEDISOL® AM – MEDIFLEX® AM (made from PVC) and MEDISOL® AMHF – MEDIFLEX® AMHF (made from halogen free raw materials) in nominal outer diameters from Ø16 to Ø63, according to ΕΝ 61386.01, along with a complete series of fittings (bends, couplers, clips, adaptors) and junction boxes.

Protection & identification in buried underground networks

The management and protection of buried underground networks, the protection of the personnel performing technical installation or maintenance tasks and the facilitation of engineer’s work providing a better and safer way of networking, lead KOUVIDIS to design and invest in the development of plastic pipes with three different walls.

The first generation was presented in 2012, gaining electricians and engineers respect, while the second generation with color marking was launched in 2017, upgrading the way of cable protection and management in buried underground networks.

The color identification of the new second generation GEONFLEX & GEOSUB conduits follows the rules set by the Standard NF P 98-332 which specifies the pipeline coloring according to the application field and the minimum distances buried pipes should have between each other.

Applying its 9 years manufacturing know-how on structured wall conduits, KOUVIDIS presented in 2019, a new even smaller diameter of Ø 32 providing more flexibility in buried underground installations.

KOUVIDIS is the only European company that produces plastic conduits for buried underground networks in diameters of Ø32.

We do not rest, we are continuously working to improve all our products production process

Need

The underground routing of the public utility networks for safety reasons (avoid exposure to extreme natural phenomena and transmission of electromagnetic radiation) and the upgrading of the urban environment (better aesthetics since they are not an eyesore).

Research

The design of a robust, easy to use and environmentally friendly product that will protect the cables from external factors and will facilitate the installation and accessibility to the network combining the properties of a pliable and a rigid pipe at the same time.

Manufacturing technology

Welding of three different walls during the production process through co-extrusion. The corrugated external wall of the conduit provides the necessary flexibility and the required mechanical strength with the use of less raw materials. The internal smooth wall ensures the smooth insertion of the cables during the installation/replacement.

Generation

Acquisition of two fully automated production lines, from top European companies, that produce double structured wall HDPE conduits, in nominal outer diameters from Ø32 to Ø250, with the brand name GEONFLEX® and GEOSUB® with mechanical resistance N750 (the maximum resistance according to EN 61386-24) and L450 respectively.

Halogen free products

Fire is amongst the most unpredictable threats and possibly one of the major sources of insecurity for communities, especially when occurring indoors, where chances for evacuation are limited.

KOUVIDIS halogen free and low smoke conduit systems have been designed in such a way in order to develop an additional protection in a burning building while they ensure high impact resistance in extreme low temperature conditions (-45oC).

Even in the more organized spaces, the inspection on the suitability of construction materials should be of paramount importance.

Need

Preventing adverse incidents with fatal outcomes due to the use of unsuitable building materials in public gathering places.

Research

Designing a product made from top quality raw materials that will not release any toxic or corrosive gases or emit a dense wave of smoke in case of fire.

Manufacturing technology

Halogen free and low smoke raw materials supplied by the top plastic manufacturers as well as the design of a fully-automated production line (extruders and injections) of latest technology.

Generation

Two integrated conduit systems, available in heavy and medium type according to their compression resistance, with brand names CONDUR® HF- CONFLEX ® HF and MEDISOL® HF – MEDIFLEX® HF in nominal outer diameters from Ø16 to Ø63, according to ΕΝ 61386.01, along with a complete series of fittings (bends, couplers, clips, adaptors) and junction boxes.

Anti – rodent protection

The sense of smell of rodents is much more developed than in human. The plasticizers and the aromatic odors of polymers, the bright colors and the texture of polymer products are all responsible for rodents being attracted to plastic goods. A damage in an electrical installation that consists of mainly plastic parts (pipes, junction boxes, cables, etc.), due to a rodent attack, can cause a potential damage to the network and thus an unpredictable cost to repair it. In some cases a potential damage can cause even a fire. KOUVIDIS has developed a series of plastic piping systems with anti-rodent protection in order to maximize safety in electrical installations from potential animal attacks.

Antistatic Technology

Static electricity on surfaces may be noted in cases of friction between the surfaces of cables and the electrical conduit, either during cable installation or as a result of the duct rubbing against its protective membrane packaging.

The presence of static electricity may cause an electrostatic discharge, which, in extreme cases, may even lead to the ignition or explosion of flammable air mixtures (e.g. in industrial bakeries, sugar processing plants, paint factories, chemical processing plants, etc.).

Moreover, the presence of static electricity may damage any electronic and electrical apparatuses that form part of the same electrical installation, alter the readings of measuring instruments, or even cause an electrical injury to people, which may, in turn, lead to accidents.

In order to ensure maximum safety for both the installer and the electrical installation, KOUVIDIS has developed a special additive with multiple active substances, to protect against static electricity, offering an additional safety shield against this phenomenon.
