IVT /Germany, a subsidiary of the globally operating Würth Group, presents solutions for plumbing and heating

The company IVT Installations- und Verbindungstechnik GmbH & Co. KG is a subsidiary of the globally operating Würth Group. At its location in Rohr (Germany), IVT produces highly flexible and oxygen-tight PE-X pipes on modern extrusion lines, as well as torsion-resistant multi-layer composite pipes for use in surface cooling systems, underfloor heating as well as radiator connection and plumbing installations. The solar heating system with high-insulation solar storage units and powerful vacuum tube collectors sold under the Latento brand is an in-house development too.

Solar storage for all-year solar systems
The solar heating system Latento developed by IVT with pressure-less layer storage units has been designed to achieve maximum solar yield even when there is little sun radiation. Together with the respective CPC vacuum tube collectors, the Latento solar heating system is used where solar energy is to be used efficiently all year round. The storage units are operated without pressure, and thus achieve problem-free layer structure. The name Latento comes from the block of material that stores latent heat, floats on the storage water and buffers additional heat. At the ISH, IVT will be presenting the new smaller storage unit type Latento 300 in addition to the solar layer storage unit XXL 1000 which was presented in 2010.

Complete system cover for surface heating and cooling

The Prineto range covers the whole spectrum of applications required for the installation of surface heating and cooling systems in new buildings, large-scale industrial buildings and the renovation of older buildings. The insulation elements and installation pipes can be combined to allow a suitable flooring structure and the right type of pipe fixing for all types of subflooring.
The Prineto thin-bed underfloor heating for renovating older buildings is new, and with an overall installed height of 22 mm it can even be used with low floor structures. The range is supplemented by products for use in thermal component activation in large buildings and industrial buildings with large-volume industrial distributors, special ceiling conduits and pipe-fixing tools.

Drinking water and heating installation using the same pipe and tool

The new Prineto thin-bed underfloor heating system has been designed for renovation work in buildings with low ceilings. Together with the levelling line, the system has a total height of only 22 mm from the lower edge of the knobbed board. (photo: IVT)

In addition, IVT also supplies pipe systems for plumbing installation and radiator connection under the Prineto brand. This also includes the patented Nanotec pipe with an extremely thin metal oxygen-proof layer. New products included an extended ranges of fittings made of Cuphin material in sizes 16 and 20 mm for drinking water installations in regions with highly corrosive water. A Stabil pipe is available with a shape-stabilising aluminium sheath in sizes up to DN 50 (63 mm) for dry walling surface heating systems, central heating and drinking water distribution pipes.
The Prineto installation system makes materials management easier. The PE-X pipe material and the fittings made of special dezincification-resistant brass can be used in heating and drinking water installations as well as in compressed air systems. In addition, the use of a standard tool for slide sleeve connections makes assembly easier. This means that on the construction site, radiator connections, cold and hot water pipes of all sizes can not only be installed with the same material but also without having to change tools.

Controlled quality and international reference objects

The areas of application for IVT’s Latento solar heating system range from single family homes to large-scale solar plants for hot water supplies in hotels. The photo shows some of the IVT solar collectors on the roof of the hotel "The George" on the southern European island of Malta. (photo: IVT)

The quality level of IVT products is monitored in the company’s own laboratory as well as through regular checks by recognised European testing centres. Last year, IVT achieved a turnover of around 30 million euros, of which about 70 percent was made in Germany, and employed around 120 people. IVT expects double-digit growth rates for the future, too, and is planning to develop additional European and international markets. At the moment, Austria, Italy, the Benlux countries, Russia and China are the main export destinations. For example, Prineto pipes were installed in the Tsar Church in Yekaterinburg in Russia, and in the biathlon centre in Chantymansisk. In China, Prineto pipes made in Germany were used for the supply technology in the Olympic trains in Beijing. One reference building for IVT that is unique so far is an Ikea store in Brisbane, Australia, where a Latento solar system is used for heating. If necessary, IVT receives backing in processing international projects from branches of its affiliated company Würth, which supports local logistics in cooperation with those involved in the project.
