Bobbin Immersion Heater

Marathon make Ceramic Bobbin Heaters are fabricated from high temperature factory insulators in various diameters and lengths for any voltage or wattage within manufacturing limits. Bobbin heaters are made with sheathed and without sheathed material.

The sheath material ranges from nickel plated mild steel, Income alloys and stainless steel. Resistance wire are supported on refractory insulators and connected to a terminal block at one end. Thermo well can be provided for accurate temperature sensing or other controls can be provided as well. They are normally manufactured for horizontal mounting, but may be specially designed and constructed for vertical installation.  Designed for any voltage or wattage within manufacturing limits. These Bobbin Heaters consist of elements, which are exposed partially in air for better transmission of heat. Also, when it is inserted into a radiant/immersion tube, it offers a large heated area to the liquid or semi-solid to be heated.
