The exhaust gas heat exchanger uses the waste heat generated during energy generation in the form of flue gases. To make effective use of the available heating power, the residual heat of this exhaust gas is used to add it to a second medium – for example the heating water. In this way, the existing residual heat can be significantly reduced by using it for recovery.
The efficiency of the own plant increases noticeably by this technology, whereby expensive primary energy can be saved, and the CO²-emission can be reduced. It is therefore not only cost-effective, but also environmentally friendly.
Often a exhaust gas heat exchanger can achieve a similar result for a fraction of the cost as a complete replacement of the heating system. It uses the lost heat, for example, to preheat or keep warm other tools, moulds and spaces for the manufacture of a product.

Within the industry exhaust gas heat exchangers are becoming more and more popular due to rising energy prices. Recovery from waste heat is particularly attractive when no energy can be saved directly as a result of increasing consumption.
In addition to saving energy costs, the reduction of CO² emissions also plays a major role. With a reduction of the required primary energy of up to 16%, pollutant emissions are also reduced accordingly, which is particularly important in energy-intensive industries.
An exhaust gas heat exchanger can be used wherever waste heat is generated by flue gases. This is the case, for example, in bakeries, Hardening plants or plastics processing plants. Due to modern manufacturing processes, these industries cannot do without high temperatures and the associated waste heat and therefore use precisely this waste heat to make their production more efficient.
A conversion of this otherwise wasted energy of up to 96% into reusable heat or even electric current increases the effectiveness and economy of the entire production. This makes the flue gas heat exchanger particularly attractive, as the low-maintenance unit hardly requires any continuous costs.
Every heating system produces waste heat, which is lost unused in the form of exhaust gases, for example. Of course, the exhaust gases cannot be used directly for heating.
To still be able to use the exhaust, an exhaust gas heat exchanger can be used to heat the heating medium. This means that the heat is no longer lost, but used to generate energy, without any additional consumption or costs.
In practice, the exhaust gas heat exchanger is therefore installed between the boiler and the chimney or similar, so that it is not necessary to dismantle the entire system or replace the boiler, which is costly. This saves both time and money. The exhaust gases are therefore not only reduced because the energy used is practically recycled, but the installation of such a technology is also relatively simple and the maintenance takes hardly any time.
Another major advantage of the exhaust gas heat exchanger is that it usually uses water for heat recovery. This means that some of the pollutants can already be filtered out of the flue gases and thus also reduce the strain on the filter systems.
No matter for which application the exhaust gas heat exchanger is to be used, special solutions from exodraft, adapted to the individual requirements, always offer the best efficiency with minimum maintenance intensity.
Due to the wide variety of materials and designs, a wide variety of heat exchanger designs are available. Examples are finned, plain or finned tube heat exchangers. Classic are air heaters – the most commonly used design. They are used to heat air or other gases for later use, for example for indoor air.
Air coolers, on the other hand, extract the heat from a material flow and pass it on to a cooling medium. For example, an in-house air conditioning system can also be implemented without enormous energy consumption. Process engineering processes that require low temperatures also benefit from this. It is often necessary to control the temperature of extremely high excess heat to maintain the desired temperature.
A heat exchanger helps to absorb or dissipate heat according to your specific requirements.
Flue gas heat exchangers are also suitable for other material flows. In addition to air, these can also be (service) water, oils or other gases. The process uses only waste heat and does not contaminate or mix the substances themselves.
Nowadays there are hardly any restrictions for flue gas heat exchangers when it comes to application areas. There are already universal solutions for many areas and applications. We make sure that you get the most suitable flue gas heat exchanger for your use. In some cases, an individual flue gas heat exchanger can be advantageous to achieve maximum heat recovery.
For exodraft’s exhaust gas heat exchangers to meet even the most difficult requirements, they are manufactured with the best materials for the right purpose.
In addition to stainless steel and copper, these include nickel heat exchangers, for example, which offer very high resistance to an acid- or alkaline-rich environment. High-quality materials as well as production and assembly by trained personnel guarantee that your heat exchangers always fulfil their task economically.
The high efficiency and long service life make exodraft flue gas heat exchangers the most compact on the market. This means that heat exchangers can be used directly at the heat-generating source without affecting production.
