Heat Treating Processes
Advanced Fire Protection Engineered For High-Temperature Industrial Environments
Heat treating operations play a critical role in producing durable, high-performance metal components. But with extreme temperatures, vaporized oils, and continuous cycling, these environments present some of the most challenging fire risks in manufacturing. KiddeFenwal delivers Kidde Fire Systems branded detection and suppression solutions built to protect personnel, equipment, and production continuity, even in the harshest conditions.
Understanding the Risk of Heat Treating Processes
High heat, flammable oils, and constant motion create a perfect storm for industrial fires.
Heat treating involves heating metals to precise temperatures inside industrial furnaces, then rapidly cooling them using air, salt, specialized quench fluids, or oil. Oil-quench systems, the most common method, introduce significant fire hazards:
- Vaporized oil can ignite inside open or enclosed quench tanks
- Drip pans and oil-coated components can accumulate residual fuel
- Fume hoods and exhaust ducts can pull burning vapors into confined spaces
- Continuous furnace throughput increases the risk of ignition
- Restart conditions may expose overheated oil to fresh oxygen
Without fast detection and immediate suppression, fires can escalate rapidly, endangering workers and causing costly downtime.


Built for Extreme Industrial Conditions
Fast-acting suppression and early detection reduce risk in high-hazard environments.
- Rapid CO₂ Suppression
High-pressure CO₂ systems smother surface fires on oil baths, drainboards, and exhaust areas within seconds — protecting equipment and personnel. - Process-Integrated Detection
Heat detectors monitor conveyor paths, quench tanks, and ducts for rapid ignition events. - Continuous Monitoring
Smart control systems provide real-time oversight of critical areas where temperature extremes and oil vapors are constant. - Flexible System Design
Solutions can be configured for open, partially enclosed, and fully enclosed quench tanks, including auxiliary hazard zones.
Applications
KiddeFenwal fire protection and detection technologies support a wide range of heat-treating operations, including:
- Open quench tank systems
- Enclosed quench tanks and quench cells
- Furnace discharge and conveyor areas
- Oil drip pans and drainboards
- Fume hoods and exhaust ductwork
- Heat-treat process lines and finishing areas
- Auxiliary electrical rooms and control cabinets
Our engineers work directly with manufacturers and facilities to tailor solutions that meet equipment design, quench methods, and operational requirements.
Our applications engineering team works with channel partners (engineered systems integrators) OEMs, and end users to determine the right detection, activation, suppression, and venting requirements for each dust collection application.
