In low-temperature fluid transportation or storage, a drop in medium temperature may affect flowability or process stability. When selecting a model, technical engineers need to determine heater parameters based on medium characteristics, installation conditions, and temperature control requirements. The JHR-35 sheathed electric heater is suitable for such scenarios. The following provides selection references from several aspects.
The sheath serves as an isolation layer between the heating element and the medium, and its material directly affects heat transfer rate and corrosion resistance. During selection, the corrosiveness of the medium must be confirmed: carbon steel sheaths can be used for neutral fluids; stainless steel 304 or 316L sheaths are recommended for weakly corrosive media. The JHR-35 offers a detachable sheath design, making it easy to clean surface scaling or replace the heating core, reducing downtime.
Heating power must be calculated based on medium flow rate, temperature rise requirements, and heat dissipation conditions. The JHR-35 supports a customizable power range, with common voltages of 220V or 380V. During design, ensure that the power supply capacity matches the protective devices to avoid overload. For media with poor flowability, the surface load can be appropriately reduced to prevent local overheating.
The installation position should avoid dead zones of medium flow to ensure the heater fully contacts the fluid. The JHR-35 uses standard flange or threaded connections, making it easy to integrate into tanks, pipelines, and other equipment. During maintenance, regularly check the sheath surface condition and clean deposits to maintain heat transfer efficiency. The heating core can be replaced separately, reducing long-term use costs.
This model is suitable for low-temperature fluid heating scenarios, such as chemical raw material tank tracing and pipeline anti-solidification. During selection, it is recommended to provide the medium name, operating temperature, flow rate, and environmental conditions to match the sheath material and power configuration.
