In the design and selection for explosion-proof areas, the same heating power requirement often involves inconsistencies in flange specifications, terminal enclosure structure, and surface load values, which complicates later installation and spare parts management. The FBR-72 stainless steel explosion-proof heater is intended for such scenarios, allowing design and selection personnel to verify each item according to on-site conditions.
The heating element uses stainless steel tubing, with the terminal enclosure and heating section arranged in separate zones, suitable for air and liquid heating in environments where flammable gases or vapors are present. Flange specifications, tube bundle length, and wiring method can be matched to the installation interface and spatial conditions, facilitating connection to existing tanks and pipelines.
The maximum operating temperature is 300°C. It is recommended to measure temperature once a month, and the terminal enclosure temperature should not exceed the ambient temperature by 20°C. If the circuit is normal but the temperature rise is abnormal, the set value and sensor status of the temperature controller should be checked before determining the condition of the element.
During the design stage, it is advisable to simultaneously confirm the medium properties, allowable surface load, flange standard, and supply voltage, to avoid interface mismatches caused by selecting solely based on power. When purchasing spare parts, recording and archiving by model and parameters can reduce the verification workload for subsequent replacement.
