For environments where hazardous area certification is not required, a low-cost option that can be considered is the LMK Thermosafe® Flexible Top Hat. This heavily insulated cover is made using high temperature rated silicone coated glass cloth. A pull cord and brass eyelets allows the soft top hat to be easily tightened around the exposed top portion of the 55-gallon steel drum to retain the heat.
- Increases the efficiency of the heater

A rigid hard top version (SKU #RTH) is also available and is rated for hazardous or explosive environments.
