| Flex Silicon and Drum Heaters |
| Drum Heaters facilitate the handling of solidified or viscous materials like adhesives, waxes, tar, chemicals, oils etc. They eliminate cumbersome methods and high investments, associated with steam and oil or fire wood heating. |
| |
Construction
Drum Heaters consist of a cylindrical metal cover carrying the flexible heating elements. A 2" thick thermal lagging of glass wool provides insulation and the metal casing makes for a rugged unit that can be wrapped snugly around the drum. The Drum Heater is hinged, and is mounted on castors for convenience. A base heater, also encapsulated in metal provides bottom heating. Control Panel incorporating thermostatic control is provided with the heaters. |

- Electrical Connections
Electrical resistance heaters are electric heaters manufactured by the interposition between the layers of dielectric insulating material (silicon) made of a resistive circuit innovative technologies such as etching foil, inks or pastes tank.
In this way, elements can be constructed with very thin flexible, which can adapt well to the observations of the surface to be heated which are placed in direct contact to allow for better heat exchange. |

• The surface temperature of the caefactores hotform ® silicone it can not exceed 200 º C continuously
• Can withstand 250 ° C leads Temperatures above 300 ° C destroy the silicone.
• The table at right shows the relationship between surface charge and temperature heaters unregulated.
• The maximum values for the surface charge are:
• 0.60 W/cm2 for self-regulating heating, depending on the application.
• 2 W/cm2 for heater regulated with thermocouples and temperature regulators.
