Reverse Band

Reverse Ceramic Band Heaters are intended for the outer surface of the band to heat the inner surface of a cylinder. These heaters use the same built-in insulation as normal ceramic bands and therefor can either reduce the power needed to heat an application to the desired temperature or offer some thermal protection to anything else that might also be inside the cylinder.

Optional Double Insulation (D): 1/2

Standard built-In ceramic fiber insulation 1/4" thick on all Ceramic Bands; will reduce power consumption by 25 to 30 percent and lower external temperatures (when compared to uninsulated band heaters).
Optional built-in ceramic fiber insulation 1/2" thick is available; for situations requiring additional insulation for lower external temperatures and increased electrical energy savings. This will decrease power consumption by 35 to 37 percent (when compared to uninsulated band heaters).

Type R: Uninsulated Ceramic Band Heaters

Type R Construction is an uninsulated ceramic band heater with a perforated Stainless Steel outer shell for more efficient cooling.  It is typically used in multiple quantities with forced air cooling systems such as Tempco's Cool TO-THE Touch Shroud Systems (see Type RCC below).

Type RCC: (Ribcage) Heating Mounting Configuration

This system was developed to reduce the cost and weight of typical shroud systems for the heating and cooling of high temperature extrusion processes.Type RCC (Rib Cage) Air Cooled Systems use multiple Type R Ceramic Band Heaters under one shroud.
