Industrial drying at low temperatures – functional principle and advantages
The core principle of HARTER technology is the closed air circuit with integrated heat pump. The process air is dehumidified, tempered, and reused – a circuit without external or exhaust air. This keeps the drying process independent of the outside air and constantly controllable.
Advantages at a glance:
- uniform results at temperatures from 20 °C to 75 °C
- up to 70% less energy consumption compared to hot air systems
- no dust or germ entry due to exhaust air-free design
- stable processes for sensitive materials
The systems can be precisely controlled – temperature, air volume, humidity, and drying time remain constant throughout the entire process.
This ensures consistent product quality with minimal energy consumption.
How HARTER efficiently expands production capacities through modular solutions is described in the article Expanding capacities with heat pump dryers.
Drying systems for industry
Industrial drying at low temperatures – applications and system diversity
HARTER’s technology is versatile and suitable for almost all industrial sectors:
- Food and feed: Gentle drying of sensitive products, preservation of color and aroma
- Chemicals and pharmaceuticals: Precise residual moisture levels, validatable processes
- Metal and plastic parts: Fast, spot-free drying after cleaning or coating
- Surface technology: Electroplating and paint drying without heat distortion
- Sewage and industrial sludge: Reduction of volume and disposal costs
Each system is precisely tailored to the product, volume, and line layout. Whether batch or continuous drying – HARTER delivers customized systems that can be integrated into existing processes.
Original products are tested in advance in the company’s own technical center. Airflow, temperature, and humidity are specifically determined to define the optimal process window. This guarantees reliable results for testing, validation, and series production.
We dry with dry air and deliver it to the right places: A perfect interplay of air preparation and air guidance provides you with the best possible drying result.
Reliable – Competent – Long-term
Service that thinks ahead – for years to come
With the HARTER After-Sales Service, you secure a reliable and efficient drying solution for the long term. Whether it’s maintenance, spare parts supply, or technical adjustments – we support your system throughout its entire life cycle and ensure that it delivers optimal results at all times.
Industrial drying at low temperatures – sustainability and future security
The combination of heat pump, closed air circulation, and heat recovery makes HARTER systems particularly efficient.
Energy consumption is significantly reduced, and waste heat is fully utilized – a real contribution to climate protection.
Sustainable advantages:
- up to 70% energy savings
- significantly lower CO₂ emissions
- reproducible quality without energy waste
- low-maintenance, durable technology
Thanks to their modular design, the systems can be adapted to changing production volumes. They can also be combined with photovoltaic or heat recovery systems. Many HARTER solutions meet the requirements for energy efficiency and environmental support programs.
