Ceramic Band Heater Calculation

Band heaters general description.

Ceramic band heater calculation.

Ceramic knuckle band heaters offer lower operating cost because of superior insulation less heat escapes to the air and less wattage is required to maintain barrel temperature. Ceramic band heaters by thermal corporation provide long life and use less wattage because of insulation in plastics extrusion and injection molding applications. A simplified formula for calculating the heat loss due to natural convection is. When selecting a ceramic heater select a heater that best matches the wattage requirements to decrease the frequency of cycling and temperature overshooting and thereby increase the life of the heater.

Ceramic heater bands offer higher operating temperatures and longer heater life because all materials used are rated to operate at very high temperatures. Proheat s high performance ceramic heater band for processing high temperature engineering resins. Of a ceramic heater we can say that the consequences of an accidental encounter are less severe than an experience with a mica band. Ceramic heaters are available with different terminal styles are fully flexible and can accommodate holes and cutouts.

These heaters are low cost but not. When installing a ceramic band heater to replace a non insulated heater decrease the total operating wattage by approx. Ultra thin ceramic band heaters 3 8 thick 3 16 thermal insulation up to 65 watts sq. Click to see all our ceramic heater band styles.

Band heaters are manufactured in many different configurations. These band heaters are constructed with a stainless steel shroud enclosing high quality ceramic knuckles through which run coiled high temperature nickel chromium element wire. They are durable and have built in ceramic fiber jackets making them energy efficient. Band heaters provide countless solutions for cylindrical surface heating applications.

The band heaters used now a day are classified according to the insulators used in them as below. Ceramic band heaters afford customers a means to heat large cylinders from intermediate to high temperatures of 1600 f 870 c without concern of failures due to hot spotting that conventional bands heaters are susceptible to when used on large diameter cylinders. Mica band heater mica strip are usually used to insulate resistance band heaters. Ceramic heaters are medium to high temperature band heaters with a 1200 f a maximum working temperature.

L convection surface loss w in 2 x area x 1 hr continuing the tin block example assume the block resting on the mica plate is surrounded by air that is not moving except for that which is rising after being warmed by the block. We offer a variety of ceramic band styles from standard to custom configurations. For other cylindrical or non cylindrical surfaces we recommand cartridge circulation immersion strip tubular or flexible heaters. Ceramic fiber insulation reduces power consumption by 20 to 30.

Ceramic bands integrate a layer of thermal insulation that reduces ambient heat loss and reduces power consumption.
