about us
Seit 1988, also seit mehr als 30 Jahren beschäftigen wir uns mit der Fertigung von Hochtemperatur-Dämmsystemen. Gemeinsam mit unseren Geschäftspartnern entwickeln wir das für alle gängigen Abgasstufen beste Lösungsmodell für Anwendungen beim Fahrzeugbau, für Gasmotoren, Dieselmotoren und auch für die neuesten Hydrogen-Motoren, sowie für Nutzfahrzeuge und Baumaschinen, On- und Offroad-Applikationen etc. unter Berücksichtigung aller gültigen Vorschriften für eine optimale Abgasnachbehandlung. Unsere Integraldämmungen unterstützen insbesondere das Thermomanagement bei hochkomplexen Abgasnormen wie Euro 6, Tier IV final oder Stage V. Wärme erhalten, wo sie am meisten gebraucht wird - mit Kavarflex- oder Kavartherm-Dämmsystemen als Wärmedämmung, Hitzeschutz und Wärmespeicherung für: Abgaskrümmer Abgasrohre Entkopplungselemente Dieselpartikelfilter Abgasnachbehandlungssysteme Hardware Nachrüstung sowie für alle heissen Bauteile im Motorbereich bzw. Abgasstrang Durch den Einsatz von der textilen Integralisolierung oder metallischen Integraldämmung wird der Temperaturverlust zwischen Motor und Abgasnachbehandlung auf ein Minimum reduziert
calcium-free insulation
Another milestone in the company's history was the development of calcium-free insulation elements, especially as high-temperature insulation for engines and turbines in 2021.
On more and more construction sites, power plants and combined heat and power plants, traces of the carcinogenic and mutagenic element calcium chromate (CaCrO4) are found both on the stripped equipment, such as engines and gas or steam turbines, and on the inside of the insulation elements after the insulation mattresses (also known as insulation blankets, insulation mats, etc.) have been removed.
The toxic heavy metal compound can be formed mainly as calcium chromate (CaCrO4) when chromium components in the alloy of the insulated surface, such as chromium (III) compounds encounter calcium oxide (CaO) under thermal conditions, usually in a temperature window between 300°C and 600°C.
Calcium oxide is a component of almost all common insulating fabrics and insulation materials on the market and can also be released under certain circumstances (this is called leaching; the so-called "glass core" containing calcium oxide is by no means as inert as some manufacturers like to propagate) and thus becomes an involuntary accelerator (catalyst), which enables the high oxidation of harmless trivalent chromium compounds to hexavalent chromium compounds, which are classified as extremely hazardous (carcinogenic, very toxic to aquatic organisms with long-lasting effects and harmful to health if swallowed (source: ECHA)).
The result is toxic dust deposits on the equipment, mostly in the form of calcium chromate (CaCrO4), which must be specially cleaned at great expense, and contaminated insulating elements that should not be reused under any circumstances and must be properly disposed of as toxic hazardous waste.
Unfortunately, many insulating companies do not address this dangerous issue, so that assembly personnel are exposed to health hazards without being informed and, above all, without being protected.
Since so far to a large extent a professional special waste disposal is renounced, chrome (VI) compounds can seep so unprotected in the groundwater!
Kavarmat s.c. has developed insulation elements and systems whose components are free of calcium oxide and thus prevent the above-mentioned chemical process.
Kavarmat insulation mats are resistant to high temperatures up to over 800°C and are also characterized by the fact that they are easy to process and do not cause itching to the greatest possible extent.

calciumfree insulation systems in UK
Times are changing and the area of responsibility is growing, including in our area of activity.
Understandably, today we are also expected to be part of aoptimal supply and value chain to be. The change from a classic service company to a provider of complete solutions is necessary and more than timely.
The core competence of our house was and is the Development and production of high-temperature insulation for our business partners in at home and abroad.
The exit of the United Kingdom of Great Britain from the EU (Brexit) has more than complicated non-European services and goods deliveries.
In this respect, a reliable local partner is required who not only knows us and our products very well, but also stands for sustainability, occupational safety and environmental protection and works completely calcium-free.
With Hopes Generation Ltd. and its managing Lloyd Hopes you have a competent and solution-oriented specialist with many years of experience on site, who you can also entrust with further service work in the electronic and mechanical areas, especially for CHP plants (biogas, etc.).
