The Ultimate Heat!

The Ultima Series of band and strip heaters produced by TUTCO Conductive deliver a robust selection of band and strip heater options to meet the need of a variety of applications. These heaters will operate up to 1200°F (648°C) and will withstand most corrosive environments and harsh installations. Ultima heaters start with a stainless-steel tubular heating element that is inserted into a 3/8” thick x 1 1/2” wide stainless-steel sheath which is then filled with MgO to allow for quick high heat transfer. They are available with a watt density of 40 to 45 Watts/In² of heating surface. These heaters are used in many process heating applications from aerospace, custom plastic molding dies and molds to custom made solutions, like a heater used to keep a cast iron pot of soup at specified serving temperature. 

This heater style is available in a wide variety of electrical terminations. We can do basic screw stud terminals with or without a stainless-steel terminal box, high temp leads with lengths to match your system requirements with stainless steel braid, stainless steel armor and fiberglass sleeving protection available. We can also offer a stainless-steel terminal box with a German Plug installed into the terminal box. We can also offer a variety of other plugs, just let us know what plug you require, and we will evaluate and should be able to offer it to you. 

The TUTCO Ultima Band heaters can be built with Inside diameters from 5” to 30” and larger diameters can be evaluated and sometimes built. These heaters come standard with 2-piece construction but some designs can be built is 3, 4, or possibly more segments. 

The clamping hardware is heavy duty 1/4-20 SHCS w/ clamp bars with spring bolt and Belleville washer clamping optional. The TUTCO Strip heaters are available from 5 to 50” in length but longer lengths may be possible but need to be evaluated by the factory. These heaters will look very similar to a standard ceramic strip heater but they are much more robust with optional mounting tabs, brackets and even fins for rugged air heating applications. 

If you need a non-standard Ultima heater, please consult the factory and we will be happy to evaluate and see if we can offer you something to meet your needs as we are happy to do custom configurations. Please contact us; we would love to help you with all your conductive heater needs whether it be the Ultima product line or another one of our other conductive products.
