Innovation and development are our future's keywords
No company can ignore the time factor "be always up-to-date", technical expertise and the strength of Innovation.
At the same time different customer groups demand the individualisation of basic products from the mass production, which means for a company like Konvekta to be extremely flexible in the development of design and product varieties.
Konvekta identifies future needs early and realizes with high competence new path-breaking solutions and products . The most lightweight air conditioning system or the air conditioning system using CO2 as a refrigerant which was awarded with the German Environment Award, are only a few examples how Konvekta brings path-breaking innovations to the market.
We are "always up-to-date"!
Conditioned with the refrigerant CO2 (R744) - a first step towards a clean future
Why are current refrigerant a problem?
The impact of synthetics on the earth atmosphere is recognized to be problematic to an increasing extent. The European Union has registered this fact and - on grounds of environment protection – makes strict demands on the refrigerant used in motor vehicles in its Mobile-Air-Conditioning Directive (MAC) (guideline 2006/40/EG).
As from 01.01.2011 all vehicle manufacturers are obligated to use refrigerants with a global warming potential (GWP) smaller 150 according to EG No. 842/2006 for air conditioning units in vehicles, registered as new types in the EU.
The clean alternative: CO2 as refrigerant
CO2 = R-744 is a natural part of the air and has a global warming potential of only factor 1. As it is a waste-product extracted from industrial processes and the environmental impact has been “categorized” there, it is even environmentally neutral (GWP =0) for further use. A system operated by R-744 possesses a higher degree of efficiency than an R134a-system. For the same cooling capacity about 25% less fuel is needed (UBA 2008, ADAC 2008, Hrnjak, SAE ARCRP1, 2007). Thus not only the exhaust gas emission is reduced but the operating costs, too.
Lightest air conditioning units world wide - UltraLight II
The new bus air conditioning unit series “Ultra-Light II” is the next logical step towards more efficiency and lightness – a technological statement for the future, packaged in an exciting design. In the process, the spectacular shape of the new model series is far more than a mere question of aesthetics. With its dynamic, clear-cut edges and purist surfaces it stands not only for forward-looking automobile design – but above all for functionality and aerodynamics, too.

Konvekta CO2 heat pump
The principle is very simple: Heat or cold is extracted from a natural source (air) in order to use it for heating operations in the winter or cooling operations in the summer. One KW of energy becomes 3 KW of power. (COP Coefficient of Performance = 3). The Konvekta Co2 heat pump uses Co2 (R-744) as the carrier.
Four steps to a climate of well-being
Das Kältemittel transportiert die Wärme. Im Kreislauf der Wärmepumpe übernimmt das Kältemittel CO2 (R-744) die Aufgabe, die Wärme oder Kälte zu übertragen und zu transportieren.
Air conditioning systems – do they create a climate that is conducive to mildew and bacteria?
Short-distance public transport: Hygiene in air conditioning systems
The air conditioning system has become a part of the standard equipment in several public modes of transport. Thereby, the air conditioning system of the present day is much more than merely the pleasant cooling off device for the passengers of buses and railways. Beyond an interior temperature of more than 24°C, the physical capability of the driver falls rapidly.
It is particularly in summer-like temperatures that ideal conditions prevail for harmful mildew and bacteria. A large number of people are transported in buses and railway trains, and the quantity of viruses and germs here is particularly high.
