Heat recovery in spray drying.
Spray drying processes offer significant potential for energy savings. Anytherm designs and implements heat recovery systems for spray drying exhaust air and process streams, including:
- Gas-to-gas heat recovery
- Air-to-water heat recovery
- Waste heat recovery from exhaust air, flue gas and scrubbers
We apply heat recovery optimisation, pinch analysis and process integration methods to identify the optimal heat recovery concept — and implement it in a technically robust and hygienic way, including CIP solutions where required.
Our solutions typically achieve a payback time of 2–3 years, depending on the application.
Anytherm designs integrated heat recovery systems that capture energy from exhaust air and flue gas and reuse it within the process.
Designed for industrial performance
Easy maintenance.
Extractable heat exchanger design.
Anytherm heat exchangers are designed for easy maintenance and minimal downtime. All heat exchanger elements can be fully extracted from the housing without dismantling the unit, insulation or ducting. This allows fast cleaning, inspection or replacement.
Anytherm systems are built for demanding industrial environments:
- Fully welded stainless steel design
- Hygienic execution for food and pharmaceutical applications
- Extractable heat exchanger elements for easy maintenance
- Integrated CIP systems for cleaning
- Insulated casings
- Designed for high reliability and long service life
Anytherm heat recovery and air handling systems can be equipped with integrated CIP solutions. This allows cleaning without dismantling the equipment, ensuring hygienic operation and minimal downtime.
New installations. Replacements. Upgrades.
Support throughout
your plant’s lifecycle.
Anytherm supports new spray dryer installations and retrofit projects with tailor-made air handling and heat recovery solutions. We typically support customers in the following situations:
- New spray dryer plants requiring complete air handling systems
- Replacement of existing steam, hot-water or electrical air heaters
- Replacement or upgrade of dehumidification and filtration equipment
- Optimisation of existing plants with heat recovery systems
- Upgrade of air handling performance: humidity, filtration and temperature control
- Retrofit of existing installations with limited space
Existing installations
Brunner Thermo replacement units
and spare parts.
Anytherm has extensive experience with spray drying air handling systems, including systems originally engineered by the former Brunner Thermo GmbH (Switzerland), which went bankrupt in 2020.
Our team includes engineers with long-standing experience in Brunner Thermo air handling designs, steam air heaters and heat exchanger systems.
Our experience with former Brunner Thermo systems
Following the insolvency of Brunner Thermo, Anytherm:
- Took over and successfully completed all ongoing projects of Brunner Thermo GmbH
- Employed and worked with highly experienced engineers from the former Brunner Thermo team
- Gained deep understanding of design concepts, calculation methods and system layouts
Today, we support customers worldwide with Brunner Thermo replacement units, spare parts and retrofit solutions, providing technically equivalent or optimised systems.
- Spare parts and replacement heat exchangers for Brunner Thermo systems or other industrial air handling systems
- Engineering support for existing installations
- Retrofit and upgrade projects
We combine deep design understanding with modern engineering and manufacturing to deliver reliable, efficient and maintainable solutions for existing installations.
