Permanent Heat
The Permaheat Series of band and strip heaters that are produced by Tutco Conductive in Cookeville, TN, USA, offer a great, robust option for long-lasting, low-temperature conductive heating needs (up to 600°F). These heaters have tubular heating elements formed and pressed into a machined aluminum extrusion, which allows for excellent heat transfer without the worry of most contaminants damaging the heater. They are available up to a watt density of 40 Watts/In² of heating surface. These heaters can also be built by replacing the tubular heating elements with tubing to be used in hot oil heating and chiller cooling applications. These are widely used in blown film applications along with other plastic injection molding and process applications but can be adapted to many other process applications.
These heaters will have a 20 Ga stainless steel cover for the aluminum extrusion, giving the heater a rugged construction. The heaters are available with a variety of termination styles. 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 Permaheat Band heaters are available from a 5” diameter to a 106” diameter in widths of 1-1/2”, 2-1/2”, 3” & 4”, with the thickness being 1/2”. They can be built in 2, 3, or 4 pieces depending on size and the heater design parameters. They can be built in a full band, partial band, or reverse band (heating the outside diameter, not the inside diameter). The clamping hardware is heavy-duty 1/4-20 SHCS w/ clamp bars, with spring bolt and Belleville washer clamping optional. The Tutco Permaheat Strip heaters are available 6” to 50” long standard in widths of 1-1/2”, 2-1/2”, 3” & 4”, with a thickness of 1/2”. Many different mounting hole configurations are available, but they need to be evaluated at the time of quote/order based on design.
If you need something off-standard in a Permaheat 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, and we would love to help you with all your conductive heater needs, whether it be the Permaheat product line or another one of our other conductive products.
