Anytherm supports new spray dryer installations and retrofit projects with tailor-made air handling and heat recovery solutions.
Spray Drying Applications
Our heat exchanger solutions are widely used for air handling and heat recovery in spray drying processes for the production of food, dairy, chemical and pharmaceutical products like:
- Milk powder & infant formula
- Coffee powder
- Protein powder
- Starch
- Pharmaceuticals (e.g. hormones, vitamins)
- Chemicals & fertilizers
- Battery materials (e.g. lithium processing)

Air Handling Systems for Spray Drying
All systems are 100% custom-made to match the specific process requirements, layout constraints and performance targets.
- Steam air heaters for spray dryers
- Air handling units (AHU) for spray drying processes
- Air intake and filtration units
- Sorption dehumidifiers (desiccant wheel systems)
- Cooling dehumidifiers (condensation systems)
- Compact units and high pressure units
- Custom heat exchangers for process air systems
- Heat recuperators, heat recovery systems and energy consulting (e.g. heat recovery / pinch analyses)
We provide the full scope of air handling equipment for spray drying plants:
Heat Recovery in Spray Drying
Spray drying processes offer significant potential for energy savings.
Anytherm designs and implements advanced 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
Our solutions typically achieve a payback time of 2–3 years, depending on the application.
A key advantage of Anytherm is the combination of practical equipment engineering and advanced energy consulting:
We apply heat recovery optimization (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).

Spray drying processes offer significant energy saving potential.
Anytherm designs integrated heat recovery systems that capture energy from exhaust air and flue gas and reuse it within the process.
By combining process integration and practical engineering, we ensure maximum efficiency and reliable operation.
Designed for Industrial Performance
Anytherm systems are built for demanding industrial environments:
- Fully welded stainless steel design
- Hygienic execution (food & pharma compliant)
- Extractable heat exchanger elements for easy maintenance
- Integrated CIP systems for cleaning
- Insulated casings
- Designed for high reliability and long service life
This ensures reliable operation, easy maintenance and long service life.
Engineered for Lifecycle Optimization
Unlike standard equipment suppliers, Anytherm combines process engineering, equipment design and energy consulting.
This allows us to optimize not only investment cost (CAPEX), but also:
- Reduced energy consumption
- Lower operating cost (OPEX)
- High availabilty and uptime
- Optimized total lifecycle cost
We act as a system partner on eye level with process engineers and OEMs, ensuring technically and economically optimized solutions.
Easy Maintenance with 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 – significantly reducing maintenance effort and downtime.
Our modular design allows easy access, fast maintenance and minimal downtime.
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.
Replacement Units and Spare Parts for Brunner Thermo Heat Exchanger and Air Handling Units
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.
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 optimized systems.
We support customers with:
- 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.
Typical Customer Situations
We typically support customers in the following situations:
- New spray dryer plants requiring complete air handling systems
- Replacement of existing air heaters (steam, hot water, electric, dehumdification, filtration)
- Optimization of existing plants with heat recovery systems
- Upgrade of air handling performance (humidity, filtration, temperature control)
- Retrofit of existing installations with limited space
This allows us to support a wide range of spray drying projects – from new installations to complex retrofit and optimization tasks.
Swiss Engineering, Cost Efficient Manufacturing, Internationally Competitive Pricing
Headquartered in Switzerland with production in Europe, Anytherm combines:
- Swiss engineering quality
- Internationally competitive manufacturing
- Flexible and responsive project execution
We combine highest industrial quality systems at internationally competitive prices.
