Band Heaters

Air-Cooled Ceramic Band Heater are combined with high velocity fans to form fast responding heat / cool units in accurate heating applications. These heaters are made with a perforated outside stainless steel sheath, and with no insulating jacket. Specifically designed for the blower air cooling process/applications on extrusion machineries.

Features:

• Non-thermal insulated
• Lower cost
• Replaceable heaters
• Maximum watt density = 45 watts/In²
• No leakage
• Low maintenance
• Maximized cooling efficiency
• Various Termination options

• Mica Band & Nozzle Heaters
• Ceramic Band Heaters
• “Insulation Tech” Power Saving Heater
• Air-Cooled Ceramic Band with blower Jacket

Mica Band Heaters is a proven heater design for good life efficiency and dependability. It assures maintaining the lowest winding temperatures possible, keeping a low-mass heating element assembly for fast heat-up and quick response to controls. These are provided to our customers as per their specifications.

Features:

• High quality nickel - chromium resistance wire
• Highest quality mica used for excellent dielectric strength in all designs.
• Two-piece & one-piece Construction.
• Variety of termination & Clamping
• High quality galvanized steel sheath
• Thin construction for maximum heat transfer.
• All bands are accurately rolled to the specified diameter for optimum contact.
• Sheath Material: Zinc plated MS, Brass or Stainless Steel
• Watt Densities: Maximum to 25 watts/in²
• Voltage: 230 V AC to 440 V AC
• Diameter: Min 25 mm

Ceramic Band Heaters are medium-to-high temperature heaters that have 650ºC as a maximum working temperature. These durable heaters have in-built ceramic fiber jackets that make them energy efficient. Ceramic band heaters are available with different terminal styles, are fully flexible, and can accommodate holes and cut-outs.

Features:

• Conserve heat
• High degree of flexibility
• Uniform heat distribution
• Two –piece &one –piece Construction
• Variety of termination & Clamping
• Voltage: 230 V AC to 440V AC
• Watt density: Max 45 w/in²
• Minimum Width: 25mm
• Standard Width Increments: 15+6mm
• Maximum Width: Dependent upon the ratio of diameter to width.
• Minimum Diameter: 75mm
• Maximum Temperature: 650ºC
• Flexible, easy to install and remove

• Mica Band heaters are available with energy saving options in various sheathing materials, such as Aluminized Steel, Chrome Nickel Steel, Brass depending upon applications which provides the best combination of physical strength, high emissivity & good thermal conductivity to heat cylindrical parts, good for sheath temperature upto 300°C.

• Easy to install
• Hassle free performance
• High efficiency

• Habitually, liquid cooled Cast-In Heaters have been the more frequently employed method of controlling the melt temperature of extrusion barrels.
• There is no doubt about the effectiveness and speed of liquid cooled castings in removing heat from the extrusion process.
• Air Cooled Cast-In Heaters are virtually maintenance free and therefore, when properly installed and applied, have the capability to far outlast their liquid cooled counterparts.
• Since cooling tubes are not used, the possibility of breakage, cracking or becoming clogged with brine or mineral deposits is not a concern.
• Additionally, Air Cooled Cast-In Heaters do not require an expensive cooling tower or heat exchange system, extensive plumbing systems and labor for installation.
• These factors along with the benefit of being maintenance free make MATRUSREE’s Air Cooled Cast-In Heaters an economical and practical source for your extrusion heating and cooling application.
• In certain instances where air-cooling alone will not sufficiently cool the process, liquid cooling tubes can be cast into the heater as well to maximize BTU removal.
