Industrial Heating & Drying

Industrial heating and drying supplies controlled heat for moisture removal, curing, baking, finishing, thermal treatment, material conditioning, and product preparation. These processes can support dryers, ovens, kilns, furnaces, coating lines, food and agricultural drying, wood products, minerals, biomass, and other manufacturing applications. Profire also covers food and beverage, agriculture, pulp and paper, and metals and mining.

In manufacturing, burner management is used wherever a burner heats product or the air around it: industrial dryers, conveyor and batch ovens, kilns, furnaces, boilers, thermal oxidizers on oven exhaust, and OEM heater packages. Each one needs a proven purge, supervised ignition, and a shutdown that protects both the equipment and the product inside it.

Dryer heat has to recover quickly after a load change and stay inside a narrow band, or product leaves too wet or overdried. A BMS proves flame and airflow, holds the burner on temperature control, and shuts down cleanly on a fault. In one published project, PF3100 controls held a low-temperature spray dryer below 105.8°F (41°C), with Modbus and data logging replacing hands-on temperature checks.

Dryers usually run at moderate temperatures with steady airflow, while kilns and furnaces climb much higher and often follow a firing curve: a ramp, a soak, and a controlled cool-down. That means more burners or zones, wider turndown, and tighter fuel/air ratio control at high temperature, where excess air costs the most fuel. On Profire’s lineup, that work usually falls to PF3100, built for multi-burner firing with fuel/air ratio control. You can compare it with other Profire controllers.

Combustion control helps industrial heating and drying systems maintain stable heat input, consistent burner performance, air/fuel balance, and clearer visibility into equipment operation. This supports moisture control, cure consistency, oven or kiln temperature profiles, production throughput, reduced rework risk, and finished product quality.

Profire supports industrial heating and drying equipment such as rotary, belt, and spray dryers, conveyor and batch ovens, kilns, furnaces, hot oil heaters, boilers, thermal oxidizers, incinerators, and OEM heater packages. On production equipment, what drives the scope is usually the number of burners and zones, the product being heated, and how much downtime the line can absorb during changeover.

Manufacturers should consider burner configuration, fuel source, product load, airflow, production schedule, existing field devices, plant communications, shutdown requirements, documentation, operator training, spare parts support, and long-term serviceability. For materials that create dust, fibers, powders, or other combustible residues, burner control upgrades should also be reviewed alongside site-specific ventilation, dust collection, housekeeping, fire protection, and AHJ requirements. Ovens, dryers, and furnaces generally fall under NFPA 86; see how BMS standards apply by equipment type.
