Industrial Furnace Guides – Selection, Cost, Standards
The same questions come up before every industrial furnace purchase: which furnace type suits the process, what drives the price, which standards apply. These pages answer them – vendor-neutral, and without going through a sales call first.
Decision guides, not product brochures
An industrial furnace is an investment with a service life of 15 to 30 years. The decisions taken at the outset – temperature range, working volume, atmosphere, depth of documentation – can only be corrected later at considerable expense.
The pages below collect what we most often end up explaining in consultations. The aim is to let you write a solid requirements list before you start comparing quotations.
What Does an Industrial Furnace Cost? 7 Cost Drivers
Industrial furnaces have no catalogue price. These 7 factors decide what yours costs – from working volume and temperature to qualification and running costs.

Which furnace type suits my process?
Three variables decide it: process temperature, charge weight and the required temperature uniformity. Below 860 °C, forced air circulation gives the best uniformity; above it, radiant heat dominates. The guide Which industrial furnace for which process walks you through the selection step by step.
What does an industrial furnace cost?
There is no catalogue price, because every furnace is engineered around the process. Price is driven mainly by working volume, maximum temperature, atmosphere, degree of automation and the effort required for qualification and documentation. The guide What does an industrial furnace cost explains each factor.
Are these pages vendor-neutral?
The selection criteria and standards explanations apply generally. Where we point at specific model ranges, those are NTH Therm furnaces – the underlying physics and the requirements of the standards are independent of that.
