Energy recovery

Energy recovery

Envirotec offers corresponding heat recovery units for all systems to ensure optimum utilization of the energy sources used. By using this technology, an active contribution can be made to conserving resources and reducing CO2 emissions. For example, energy required in the process can be provided in the form of thermal oil, water, steam or air.

Real added value for your energy cycle.

Operating principle

Thermal exhaust air purification generally generates thermal energy, which can be recovered and reused in the production process or in other areas. Various heat transfer media are conceivable for this purpose. In general, the recovered energy can be transferred to other processes by using thermal oil, steam, water or air.

Industry solutions


Energy recovery makes sense for all applications and usually pays for itself after a very short operating time. The appropriate recovery system must be adapted to the respective application and the individual applications.

The following systems can be used for this purpose:

  • Air preheater
  • Warm or hot water
  • Thermal oil
  • Steam

Technical data

When using thermal exhaust air purification systems, an individual evaluation of the processes is generally necessary in order to achieve optimum and sustainable utilization of the energy used. The most suitable system must be designed and optimized for each individual case.


  • Can be combined with all system types
  • Can be connected to all processes and integrated into customer systems
  • Significant reduction in the primary energy used
  • Improves the sustainability of the entire process
  • Reduction in operating costs
  • Short amortization times (ROI)
  • Low maintenance requirements
  • Robust design
  • Low space requirement, thanks to the compact design and comparatively low weight
  • The system can be installed indoors/outdoors, horizontally/vertically, on a foundation/steel structure or on a roof
