Knaus Tabbert, Mottgers

Feel-good technology makes cold feet a thing of the past

ktg_cmykThe times of spartan boxes on wheels offering minimum comfort are over. People who have caravans nowadays are not looking for an alternative to the comfort they enjoy at home; on the contrary, they expect their mobile home to meet the same high standards. The new KNAUS and TABBERT caravans and RVs satisfy 5-star feelgood requirements, including underfloor heating. An extremely thin high-tech film from Frenzelit, which converts a small amount of electricity into a large amount of heat, puts an end to cold feet.

aussenansicht-vivaldi-550_dvHICOTEC® TP leaves no caravan enthusiast cold

The unique HICOTEC® TP (= Thermal Power) heating system is a development by the “New Materials” Division of Frenzelit-Werke GmbH & Co. KG (Bad Berneck / Germany). HICOTEC® TP combines composite fibre materials with electrical heating functions. The perforated composite film is a fibre-reinforced PET film with incorporated copper contacts. Since the electrical surface resistance level can be varied as required, these materials can be used as electric radiant heating elements, e.g. to heat floors, for interior components or as process heating equipment. The extremely thin film (80 µ - about 4x as thick as a interieur_puccinihuman hair!) is fitted between the floor and the floor covering, without changing the height of the floor to any noticeable extent. Capacities of 95 W/m2 are achieved via the low-voltage power supply system. The film guarantees consistent heat distribution over the entire surface with only minimal temperature fluctuations. An ideal solution to create a thoroughly pleasant atmosphere in caravans, RVs, boats or other mobile environments – following very short heating-up and without motor operation.

Perforation guarantees perfect bonding

These films were used for the first time at the Knaus Tabbert plant in 1_2-detail-perforiert-11_2Mottgers / Germany. The Frenzelit engineers supported Knaus Tabbert to develop, test and implement the HICOTEC® TP application in series production in the context of the development partnership between the two companies. Due to the design of the heating film, it proved to be very easy to install. The heating system is laid directly on the adhesive layer from the reel without any additional advance treatment. As a result of the perforation of the film, very good bonding can be achieved between the substrate material and the floor (PVC in the case of the KNAUS and TABBERT brands) with a single layer of adhesive. There are no noticeable differences in the height of the floor even when the material is not laid to cover it completely, since the film is extremely thin.

fzn001-hicotec-leitfaehig-gThanks to the insensitivity of the film to damage and thanks to the minimal contact surfaces of the functional fibres used, it is no problem to drill holes and make cut-outs in the course of subsequent assembly operations, while no short circuiting or malfunctioning occurs when screws are attached to the floor either. A feel-good environment supplied in reels – a process that is suitable for retrofitting applications too.

All the latest RVs and caravans from the Knaus Tabbert Group have been supplied with the facilities “made by Frenzelit” that are required to create a pleasantly cosy atmosphere since October 2007. This is opening up a new dimension in travel – combining face-to-face encounters with nature outdoors with an indoor environment that permits luxurious living in comfort that leaves nothing to be desired. A concept that for the very first time rz_05_05048_6makes the freedom of caravan and RV travel an appealing alternative for attractive target groups.


Frenzelit product range

Gaskets and gasket materials

Comprehensive know-how acquired over a period of many years and process engineering skills enable Frenzelit to set new standards in the production of modern sealing materials. Frenzelit supplies a complete range of gaskets, with novaphit®, the generation of gaskets made from pure graphite reinforced with expanded metal, the material concept novatec® - “engineered graphite with Kevlar® (a trademark registered by DuPont)”, the high-pressure gasket material novapress®, the PTFE gaskets novaflon® and the metal, dispenser and screen printing gaskets novaform®.

Technical textiles
Skills in the development and processing of highly temperature-resistant fibres combined with decades of experience have made Frenzelit one of the leading manufacturers of technical textiles. The range of sealing and insulating materials consists of various product lines such as isoGLAS®, isoTHERM®, novaTEX®, novaSEAL® and isoKERAM® with different temperature limits up to 1 200°C.

Expansion joints
More than forty years of experience go into the production of our fabric and elastomer expansion joints for power engineering and plant manufacturing applications. Due to the extremely exacting demands made in operation, exclusive use is made of highest-quality special woven fabrics produced in-house from glass, SiO2-glass or aramid fibres as well as the necessary coatings. PTFE composite material and PTFE, rubber and steel expansion joints round off the product range.

The insulation range includes not only heat insulation materials such as woven fabrics, woven tapes and nonwoven fabrics from the isoGLAS® and isoTHERM® product lines but also isoplan® insulation panels and special materials for transport rollers used in high-temperature applications, novaplan® heat shielding materials and cushioning materials for acoustic insulation.

New materials
Frenzelit develops and produces a range of high-performance nonwoven materials under the name HICOTEC®. These materials are based on use of such high-performance fibres as carbon fibres. They have different properties from both technical textiles and high-performance papers. They are “new materials” for new application areas.

“It frequently takes years to discover what an idea is really worth. Or – like in this case – just a few seconds. The technology of the HICOTEC® TP radiant heating system combines high capacity with minimum weight and minimum space. Which, in turn, gives our interior designers the freedom to think about using the material not only for underfloor heating but also for wall and ceiling applications or underneath mattresses.”
Claus Müller
Claus Müller
engineering graduate, New Business Development Manager at Frenzelit-Werke GmbH & Co. KG:

“The innovative HICOTEC® TP radiant heating system enables the manufacturers of RVs or caravans to enter a new comfort dimension without making any sacrifices where their interior design concepts are concerned. Because the extremely thin film increases the height of the floor so little that it is not even noticeable. The potential applications for HICOTEC® TP have not been exhausted by a long way once it has been used for “classic” underfloor heating. There are plenty of other innovative openings for HICOTEC® TP in caravans that have not been exploited yet.”

Central Marketing Manager at KNAUS TABBERT GROUP GMBH:

“More mobility automatically means less space but neither less comfortable living nor less effective heating. A highly impressive combination of space, comfort and value for money is what makes the Knaus and Tabbert brands so distinctive. The innovative radiant heating system, for which no space has to be sacrificed, is helping us to stand out from the competition even more effectively.”

“The morphology of membrane materials reinforced with long fibres leads with the use of reinforcement fibres that conduct electricity to antistatic films which are an appropriate choice as radiant heating elements for underfloor systems or interior components when the electrical surface resistance level is set accurately.”
