Heat recovery
Heat recovery for sinter metal and metal component production
Sintering processes releases large volumes of waste heat – often as flue gas or process air at high temperatures.

Energy-efficient production with economic benefits
Sintering processes are among the most heat-intensive in the metal industry. In stages such as pre-compaction, high-temperature sintering, and subsequent heat treatment, large volumes of waste heat are released – often as flue gas or process air at high temperatures.
With Exodraft’s heat recovery solutions, this energy can be captured and reused – for example, for heating production halls, domestic water or process water. This creates a more energy-efficient production setup and delivers financial benefits for companies manufacturing gears, bushings, filters, or other precision components using powder metallurgy techniques.
The solution is engineered to operate in extreme temperature environments with continuous production – without interfering with the precise control required in sintering.
Sinter metal industry
Why heat recovery is relevant for the sinter metal industry
In sintering, metal components gain their desired properties through extremely high temperatures in long-duration furnace cycles. These furnaces are among the largest sources of heat emissions in production. Without heat recovery, this energy is lost – even though heating is often needed elsewhere within the facility.
Additionally, supporting processes such as preheating, degassing, and post-hardening are highly energy-demanding and often run concurrently. By capturing and reusing waste heat from furnaces and process air, companies in the sinter metal industry can significantly reduce their total energy consumption – without compromising product quality or precision.
This makes heat recovery an efficient and strategic solution in a sector where thermal control and energy efficiency go hand in hand.

How sinter metal companies utilise waste heat
I produktion af sintermetalkomponenter opstår der n sintered component production, heat is emitted at multiple stages – during heating, sintering, cooling and post-treatment. With Exodraft’s systems, this heat can be captured directly from furnaces, extraction systems and heat exchangers – and redirected to other uses within the facility.
Typical applications include:
- Heating of production halls and office spaces
- Domestic hot water for cleaning and staff facilities
- Preheating of process water for degassing or surface treatment
- Absorption cooling – using surplus heat for cooling during warm periods
- Export to district heating networks, where applicable
- Strengthened ESG profile and CO₂ documentation
This type of reuse not only generates energy savings – it also provides greater control over internal heat balance and improves operational flexibility.
