Clean air for induction hardening in ITG induction systems
A new induction hardening plant at an ITG Induktionsanlagen GmbH customer required a powerful extraction and fire protection solution. The aim was to safely record oil smoke and emissions, optimize fire protection and at the same time ensure reliable operation even under difficult environmental conditions.

Project details
The system combines a powerful oil smoke filter with fibreglass drainage technology and an integrated pipe fire and filter extinguishing system. Spark detectors, extinguishing nozzles and a pressure boosting system ensure a comprehensive, automated fire protection. In addition, the water-bearing fire pipes were fitted with heating tapes and insulation to ensure reliable operation even in an unheated hall.
The result: Highest process reliability, a clean working environment with significantly reduced emissions and extended filter life, which sustainably reduce maintenance costs and operating costs.
“With this solution, we can optimize fire protection, reduce maintenance costs and comply with legal requirements. The clean working environment and long filter life significantly reduce operating costs. The integrated frost protection ensures reliable operation even at low temperatures. ”
