Already 500.000 kW of low-temperature waste heat are used per hour by STELA drying plants.

A STELA belt drier is designed indivually for the customer. The most different categories of performance are covered through the modular design. There are suitable STELA belt drier systems already for smaller thermal capacities, especially for the waste heat recovery of a biogas plant e.g. for drying biogas residues and digestates.

Especially for smaller and medium thermal capacities up to 1000 kW, the STELA feed-and-turn drier is more up-to-date than ever.
Through its robust design and its technology proven in practice for decades, this drying system can dry numerous most different products, from agricultural products (like e.g. pumpkin seed, bio products etc.) up to wood chips for thermal utilization or for wood gasification.

The great number of projects and satisfied customers argues for the quality of STELA drying technology and the professional competence of the STELA team.

Depending on the place of location, the preheating of the drying air of conventional agricultural STELA driers also provides a seasonal possibility to use waste heat reasonably. Depending on the heat available, gas or fuel oil can be replaced partially or totally by the waste heat. This is, besides the considerable savings of operating costs, also a meaningful contribution to climate protection and the substitution of fossil energy sources.
