Kelvion - Experts in Heat Exchange.

Thermotec GmbH manufactures plant and equipment components from alloy steel-stainless according to customer drawings.
As an example of our work, you will find the main production fields, as well as some photographs, of completed orders.

As an internationally active engineering company for plant construction in the field of energy technology, we focus on the manufacture and sale of complete plants and components for the generation of process heat. The main media used are thermal oil, water and steam, although special media such as gases are also used as heat transfer media.
Our two main business areas are:

• Heat generation and transfer systems with thermal oil, water and steam for industrial plants and ships
• Service and maintenance for boiler and process plants

Air Heat Exchangers of Lamellae or Finned Tube Design
Temperature exchange for gasses
With air heat exchangers, there is an exchange of temperature between a gas (normally air) and a liquid. Very often air heat exxhangers are also used as waste-gas heat exchangers or smoke-gas heat exchangers for heat recovery.
Lamellae or finned tube
In order to obtain a rather large exchange surface between air and medium (liquid) inside of the heat exchanger thin plates defined as lamellae or finned tube are applied to the pipe system. This heat exchanger type is mainly used in the processing and especially in the air conditioning technology.

The heat exchanger is designed for selective heat extraction from production systems, such as annealing furnace or bakery ovens and their flues.
If no heat is required from the system, the bypass motor is activated to bypass the heat exchanger.
The heat exchanger can recover enough heat to heat a warehouse or offices within the same building. Even the complete hot water requirement of a building can be provided.
High grade stainless steels
The AWT heat exchanger is manufactured from high-grade stainless steel 1.4571/1.4404, a stainless steel that has been in use in high technology flue gas applications for several years. For high stress applications, a version of the AWT made from 1.4539 is available.
For applications involving extremely high flue gas tempratures. An AWT heat exchanger fabricated in stainless steel 1.4828, which has a high nickel content, can be supplied.
Even retrospective installation of an AWT heat exchanger can be cost-effective, praticularly in times of high energy costs, so that pay-back in two to three years can be achieved.
