How to Use

1. What You Need Before Installation

  • Jacket-type drum heater (correct size for your drum: 50L, 100L, or 200L)
  • Power supply (typically 110V or 230V AC depending on your heater model)
  • Optional: Thermal gloves for safe handling
  • Digital or dial-type thermometer (if external temperature monitoring is needed)

2. Installation Steps

Step 1: Inspect the Drum and Heater

  • Ensure the drum is clean, dry, and free from oil or grease on the outer surface.
  • Inspect the heater for any visible damage to the heating element, insulation, or plug.

Step 2: Position the Heater

  • Wrap the heater around the side of the drum, aligning it at the desired height (usually the mid or lower section for efficient heating).
  • Make sure the heating surface is in full contact with the drum wall.

Step 3: Secure the Heater

  • Use the Velcro straps, buckles, or hook-and-loop fasteners to tighten the jacket firmly around the drum.
  • Ensure it is snug but not overtightened, to avoid damage to the heater or insulation.

Step 4: Connect Power

  • Plug the power cord into a grounded AC outlet.
  • If your model includes a thermostat or temperature controller, set the desired temperature.

3. Operation Instructions

Using Built-in Thermostat

  • Many models feature a built-in bimetallic thermostat (e.g., 30–110°C range).
  • Adjust the dial to your desired setpoint. The heater will maintain the drum’s surface temperature accordingly.

Using External Temperature Controller (if available)

  • Connect the digital controller as per manufacturer instructions.
  • Insert the temperature probe in direct contact with the drum or its contents.
  • Set the desired temperature on the controller.

Heating Time

  • Heating duration depends on content type, ambient temperature, and heater wattage.
  • Viscous liquids may take 2–8 hours to reach optimum flow temperature.

4. Safety Instructions

  • Do not use the jacket heater on plastic drums unless explicitly rated for it.
  • Ensure the heater is never folded or overlapped during use.
  • Keep the heater away from flammable materials.
  • Disconnect power before removing or adjusting the heater.
  • Do not immerse the heater in water or expose it to heavy rain unless it is IP-rated.
  • Always use the heater in well-ventilated areas.

5. Maintenance & Storage

  • After use, let the heater cool down completely.
  • Wipe with a dry or slightly damp cloth. Do not use solvents or chemicals.
  • Roll and store the heater in a dry, dust-free location. Avoid sharp folds or kinks.

6. Troubleshooting

Issue

Possible Cause

Solution
