Safety & Performance Design
Janitrol Aero heating systems are engineered to safely maximize combustion efficiency under varying altitude and operating conditions. The “Whirling Flame” design maintains controlled combustion by ensuring ventilation pressure exceeds combustion pressure, preventing exhaust gases from entering the cabin airflow.
Multiple fail-safe interlock systems monitor temperature, pressure, and ignition performance to ensure safe and reliable operation.
Applications
