Efficient industrial dryers – functional principle and energy saving potential
The core of the HARTER technology is the closed air circuit with integrated heat pump. The process air is dehumidified, tempered and reused – without any exhaust air system. This keeps the drying process independent of the environment, constantly controllable and extremely efficient.
Your advantages at a glance:
- Energy savings of up to 70% compared to conventional hot air drying
- stable process conditions at temperatures from 20 °C to 75 °C
- exhaust air-free, clean operation without dust or odor pollution
- uniform residual moisture levels through precise control
- long service life and low maintenance
This efficiency is created by physical heat recovery – the waste heat from condensation is used directly for air heating.
This allows energy consumption and CO₂ emissions to be massively reduced without impairing the drying performance.
Practical examples for scaling and capacity expansion can be found at: Expanding capacities with heat pump dryers.
Efficient industrial dryers
Efficient industrial dryers – applications, designs and integration
The industrial dryers from HARTER cover a broad spectrum – from small series to continuous large-scale production. Thanks to their modular design, the systems can be optimally adapted to the product, volume and space concept.
Typical applications:
- Food industry: gentle drying of fruit, vegetables, herbs and animal products
- Chemicals and pharmaceuticals: precise residual moisture for cleanroom and validation processes
- Metal and plastics technology: drying after cleaning, painting or coating
- Surface technology and electroplating: spot-free drying of components
- Environmental technology: drying of sewage or industrial sludge
Designs and options:
- Chamber dryers/tray dryers: flexible for batch processes
- Belt and tunnel dryers: for continuous production
- Special systems: customer-specific customisation for confined spaces or potentially explosive areas
Before series production, all process parameters are tested on original products in the HARTER technical center. Here, the engineers determine temperature, air flow, humidity and drying time – the basis for a validated and scalable 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.
Efficient industrial dryers – sustainability and process optimisation
Energy efficiency and sustainability are an integral part of the HARTER philosophy. All systems operate with heat pump and condensation technology in a closed circuit. This not only saves energy, but also protects the room air – without exhaust air, without filters, without heat loss.
Sustainable advantages:
- Reduced CO₂ emissions through minimised energy consumption
- Use of waste heat within the system
- no exhaust air purification or pollutant emissions
- stable processes with constant product quality
- eligible technology according to current energy efficiency standards
HARTER attaches particular importance to long-term stability and system flexibility. Many systems can be retrofitted and can be combined with photovoltaics or waste heat utilisation. A thematic overview of all industry solutions can be found at Industries.
