Heat Treatment Systems Engineered for Precision

The NTH Therm product programme covers the full spectrum of industrial thermal processing equipment, from compact bench-top furnaces for research and quality assurance to heavy-duty bogie hearth systems handling multi-tonne charges. Every system is engineered in Europe and built to the customer’s exact specification. Standardised modular designs ensure competitive lead times; custom dimensions, heating systems and atmosphere configurations are achievable without compromising the proven base concept.

Thermal Processes: Equipment and Temperature Ranges

  • Tempering, annealing, normalising: Chamber furnaces ICO, bogie hearth IWO, table-top furnaces IBF; 50–900 °C
  • Hardening and quenching: Quenching and hardening furnaces, chamber furnaces ICO; 800–1000 °C with air, water or oil quench
  • Carburising and case hardening: Carburising furnaces; up to 1000 °C with carbon potential control and ATEX-rated options
  • Sintering and calcining: Chamber furnaces ICF, bogie hearth IWF, tube furnaces TH1; up to 1300 °C
