Furnace & Kiln Controls
Temperature control, heatup/cooldown curve automation, safety interlocks, and PLC modernization for industrial furnaces, heat treat ovens, and rotary kilns.
Controls Capabilities
Industrial furnaces and kilns demand precise temperature management, reliable safety systems, and operator-friendly interfaces. Our controls engineering covers every layer — from the PID loop to the plant floor HMI. For a detailed overview, see our industrial furnace controls guide, and learn about our burner management system capabilities for safe combustion operation.
Temperature Profiling
Multi-zone PID control with cascade loop architectures, ramp/soak programming, and auto-tuning for tight temperature uniformity across the work zone.
Safety Interlocks
Over-temperature protection, flame failure response, atmosphere monitoring, door interlocks, and emergency shutdown logic designed for reliable safe-state operation.
BMS Programming
NFPA 86 burner management system programming for gas-fired furnaces — including purge timing, flame supervision, ignition sequencing, and safe shutdown.
HMI Displays
Operator dashboards for batch tracking, alarm management, recipe management, and real-time temperature trending across all furnace zones.
Legacy Modernization
PLC-5 and SLC-500 migrations, relay panel replacements, and controller upgrades that preserve proven process behavior while improving reliability and spare parts availability.
Equipment Types
Our furnace and kiln controls experience spans batch and continuous processes across a wide range of thermal processing equipment:
Heat Treat Furnaces
Batch and continuous heat treat furnaces for hardening, tempering, carburizing, and nitriding — with multi-zone temperature control and atmosphere management.
Rotary Kilns
Temperature profiling, rotation speed control, burner management, and material feed rate coordination for calcining, drying, and thermal processing applications.
Annealing Ovens
Precise ramp/soak cycle programming, atmosphere control, and cooling rate management for stress relief and material property optimization.
Drying Ovens
Temperature and airflow control for moisture removal processes — with humidity monitoring, exhaust management, and energy-efficient operation.
Melting Furnaces
Aluminum, glass, and specialty metal melting furnace controls including charge management, melt temperature regulation, and safety interlocks.
Curing Ovens
Powder coating, composite, and adhesive curing oven controls with recipe management, conveyor speed coordination, and uniform heat distribution.
