Product catalog summary
Overview
The ProTERM Thermal Energy-Recovery Module is designed to utilize heat energy from process exhaust air to significantly reduce heating costs. It transfers heat from exhaust air to incoming outside air, eliminating the need for a separate supply-air unit and reducing heat requirements by up to 96% compared to systems without heat recovery.
Filtration and Air Conditioning Integration
ProTERM integrates filtration and air conditioning technologies, allowing for the recirculation of cleaned process exhaust air back into the workplace. When recirculation is not feasible, the system vents heated exhaust air outdoors and uses a supply-air unit to maintain optimal air balance. It can be used with wet, dry, and aerosol separators.
Heat Transfer Mechanism
The system employs a cross-flow plate heat exchanger where process exhaust air and cool outside air pass each other in separate channels, ensuring no contamination of fresh air. The exhaust air is then released through the roof, achieving high heat transfer efficiency.
Operational Flexibility
ProTERM offers normal and dual operation modes. In normal operation, exhaust air is heated by process exhaust air. In dual operation, circulating air from the plant can also be heated. During summer, outside air bypasses the heat exchanger to avoid additional heat, and an optional cooling battery can be used for air conditioning. In winter, a heating battery can warm the outside air.
Air Distribution Options
The system provides flexible air distribution options via supply air channels and air outlets around the system, requiring adequate space for optimal air distribution.
Environmental and Economic Benefits
ProTERM offers significant environmental and economic advantages, including quick amortization of investment costs, excellent emission values, and decentralized, flexible operation. It is easy to set up, integrate, enlarge, and retrofit.
Technical Specifications
ProTERM supports an airflow of 8,000 – 12,500 m3/h, with maximum cooling and heating efficiencies of 124 kW and 191 kW, respectively. The unit measures 2,000 mm in length, 2,005 mm in width, and 4,339 mm in height, weighing 2,100 kg. It features an oil-proof and corrosion-protected aluminum construction for optimal heat transfer.
Cost Savings and Amortization
The system offers annual cost savings of 5,427 EUR with an approximate amortization period of 3 years. It significantly reduces energy consumption compared to systems without heat recovery.
Additional Information
ProTERM is eligible for government aid in the form of non-refundable subsidies under certain conditions. For personalized amortization calculations, contact Keller Lufttechnik GmbH + Co. KG.

ProTERM - Thermal Energy-Recovery Module-1

ProTERM – Thermal Energy-Recovery Module Take advantage of heat energy from process exhaust air and save on heating costs ProTERM reduces the heat requirement by up to 96% compared to systems without heat recovery. The heat energy produced by the process exhaust air is direcly transferred to the incoming outside air. A separate supply-air unit is no longer required.

ProTERM - Thermal Energy-Recovery Module-2

Filtration technology and Air Conditioning technology all in one Take advantage of heat energy Ideally, the cleaned process exhaust air is returned into the workplace. However, air recirculation is often not feasible and the heated exhaust air from the machine has to be vented outdoors. A supply-air unit then provides supply air for optimal air balance. ProTERM combines filtration technology with air conditioning technology in industrial plants and takes advantage of heat energy from the process exhaust air to heat the outside air. A specially developed control system ensures optimal interface...

ProTERM - Thermal Energy-Recovery Module-3

Flexible use Normal operation or dual operation with air recirculation During normal operation, exhaust air is heated by process exhaust air. In dual operation, the circulating air from the plant can be heated additionally, if required. Cross-flow plate heat exchanger is active in normal and in dual operation mode. Cooling effect in the summer, heating in the winter The outside air is directed past the heat exchanger via a bypass in the summer to avoid additional heat. Air can be cooled as well with an additional cooling battery for plant air-conditioning. The outside air can be heated by a heating...
