Industrial dryer manufacturer – Technology with a system
HARTER has brought heat pump drying to industrial perfection. The closed air circuit principle ensures that the process air remains in the system, is dehumidified and reused – without exhaust air losses and without influence from outside air.
Advantages of this technology:
- up to 70% less energy consumption compared to conventional hot air drying
- precise temperature control between 20 °C and 75 °C
- uniform residual moisture levels for all product types
- exhaust air-free, clean operation without dust or odors
- long service life thanks to high-quality materials and robust technology
Heat pump drying is suitable for almost all industrial processes – from batch drying to continuous line integration.
How companies are expanding their production capacities with this technology is shown in Expanding capacities with heat pump dryers.
Industrial dryers
Industrial dryer manufacturer – Industries, applications and system concepts
As a manufacturer, HARTER covers a broad range of applications. Each industry has its own requirements – HARTER delivers the right solution.
Typical applications:
- Food industry: Drying of fruit, vegetables, herbs, meat or pet food
- Chemicals & Pharma: controlled residual moisture levels for powders, granules or tablets
- Metal processing: Drying after cleaning, coating or electroplating
- Plastics technology: Dehumidification of molded parts and components
- Environmental technology: Sewage and industrial sludge after chamber filter press
System types:
- Chamber dryers/tray dryers for flexible batch processes
- Belt and tunnel dryers for continuous production processes
- Special systems for individual space, volume or material requirements
All systems are tested in the company’s own technical center. Here, HARTER tests the products of its customers – sectional image, air flow, temperature and humidity are precisely determined. These data flow directly into the series design and guarantee maximum process reliability.
Further examples and fields of application can be found in the Industries section.
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.

Industrial dryer manufacturer – Sustainability, energy efficiency and future viability
Heat pump drying stands for ecological responsibility and economic efficiency at the same time. Thanks to the closed air circuit, energy is used multiple times; waste heat remains in the system. This significantly reduces operating costs and reduces CO₂ emissions.
Sustainable advantages of HARTER technology:
- up to 70% energy savings
- no exhaust air emissions or filter costs
- reduced CO₂ balance
- long service life thanks to robust components
- eligible technology (e.g. BAFA, EU programs)
Many customers combine HARTER dryers with photovoltaics, heat recovery or energy monitoring systems. This makes production not only more efficient, but also more sustainable.
How companies optimize their processes with HARTER is described in: How solutions for heat pump dryers are created.
