Cast Band Heaters

TUTCO’s cast band heaters are the toughest band available; it can withstand most rough handling, shock and vibration.

The heating element is completely isolated from the outside of the band, so it can withstand almost any type of contamination.

Cast heaters are constructed of Aluminum, Brass or Bronze and can be produced with or with out cooling tubes and an endless variety of shapes and sizes.

APPLICATIONS

Castings can be used to heat dies, extruders, chemical valves & pipelines, and also to heat & cool oil. These bands will take almost any type of abuse without failure.

Plastics – Best choice for processing engineering grade resins
Heating Pipes
Chemical Processing
Drum Heating
Semi Conductor
Food Process
Packaging

If you have a special application, Cast Bands can also be modified to meet these demands. Our engineers can utilize a variety of alternative features and options to customize the heater to your specific needs.

Lead Protection

	Plain Leads High temperature mica tape lead wire is suitable up to 842Â° F (450Â° C) max. with nickel stranded conductors. Outer jacket is glass TeflonÂ® finish. The use of MonelÂ® lugs is recommended. Better Band comes standard with mica tape lead wire.
	Sleeving Fiberglass silicone rubber coated sleeving class c -1, 392Â° F (200Â° C ) service. Provides extra insulation where wire is exposed to heat, molten plastics or abrasion. Rated 1500 volts at 428Â° F (220Â° C), except 5/16â€³ (7.9 mm) size which has no voltage rating. This size used primarily to enclose multiple insulation wires in heat and abrasion resistant covering.
	Stainless Steel Braid Stainless steel over braid is most commonly specified in applications where leads may be subjected to abrasion due to movement of the application. Lead wires may be rubbing together or passing over sharp objects.
	Stainless Steel Armor Used over leads in areas where more protection is necessary. Selected for similar applications as the stainless steel braid, in addition to applications where non-fluid contamination may come in contact with the leads. This lead protection is not as flexible as the braid. Stainless steel square lock construction.
	Convoluted Armor This is a seamless product and can be attached to the heater so that fluids do not contaminate the leads. This system of lead protection is generally associated with the â€œSealed Bandâ€ construction. Not recommended where leads are flexed in the application.

Terminals

	Screw Terminals Terminals are a very convenient way of connecting our band heaters to power; typically, MonelÂ® lugs are used to secure wiring. Supplied when heater width is at a minimum or when, in application, a buss bar is used to connect the terminals of adjoining heaters.
	Screw Terminal On Top
	Screw Terminal Along the Width

Clamping

Strap Standards

Straps can be vastly modified to fit a wide variety of bands. As wider bands are used, multiple straps will most likely be designed in. Normally barrel nuts are built into the ends: one threaded, one through hole. Slots shown are to clear termination areas. Unless otherwise specified, straps are assigned by our engineering staff to best suit each application.

Illustrated are the various available styles of clamping for band heaters. When a band is provided the material is of a low coefficient of expansion type. Width of the clamping band or the number used per heater is dictated by the design standards. There are a variety of clamping mechanisms that can be attached to the band or directly to the heater. The most common forms are the strap and strap ends. Factors influencing the type and size of clamping are:

Type of band heater
Diameter and Width
Termination type and location
Holes and notches in heater
Preferences of the user

	Belleville Clamping A clamping system is generally selected for use with large diameter heaters where additional compensation of band elongation is required. Belleville clamping comes with a standard 1/4 â€“ 20 X 5â€³ (12.7 cm) long screw.
	Spring Bolt Clamping Spring bolt clamping applies constant tension on the clamping mechanism to compensate for heater elongation once it has been energized. Spring bolt clamping comes with either a 1/4 â€“ 20 X 4â€³ (10.7cm) or 1/4 â€“ 20 X 5â€³ (12.7cm) long screw.

Heat Transfer

TUTCO HSG Band Heater, Cartridge, Conductive, Engineering Insights, Strip Heater

Thermodynamics, specifically heat transfer, is used throughout our daily lives, but not always thought of. A common practice of cooking breakfast would be one simple example. You place one type of media, your frying pan, onto a hot surface and apply the “heat”, which is your source of energy, to cook the food. The heat […]

Design With Mica in Mind

TUTCO HSG Band Heater, Engineering Insights, Mica Surface Heater, Strip Heater

Mica is a superb insulating material that is versatile and cost-effective for heater design. At TUTCO-Farnam the majority of our custom-designed heaters use mica board machined to meet the customer’s specifications. A variety of types and thicknesses of mica are available and are selected for use based on the parameters required. Design variations using mica […]

How to Correctly Install a Band Heater

TUTCO HSG Band Heater, Conductive, Engineering Insights

When installing a band heater, it is important that it be well seated on a clean smooth surface and be tightened so that good heat transfer occurs between the heater and the body being heated. The more circular the object to be heated is, so much the bet- ter. Conductive heat transfer is the best […]

Increasing Conductive Heater Element Life

TUTCO HSG Band Heater, Cartridge, Conductive, Engineering Insights, Strip Heater

Does continuous operation shorten heater element life? It’s a common question, and frankly, the answer is yes. All heating wire will eventually fail over time, but it is possible to improve the life of the heater by following these recommendations. All heater types require a balance of cooling and voltage control to avoid overshoot failures. […]
