Specifications

Barrel Heater:
1.Reduces Down time for replacements
2.Easy installation and removal
3.Various Lead Terminations & Clampings

Description:

Band Heaters are designed and manufactured with more than 40 years of practical experience, for superior performance and life expectancy. As a manufacturer specialized in industrial electric heating elements & the desire to provide quality products and services to our customers both OEM’s & End Users, PHP specializes in designing Ceramic Band Heaters , Mica Band Heaters, Nozzle Heaters & Strip Heaters to your exact specifications.

Depending upon applications PHP Ceramic Band Heaters are manufactured with high temperature oxidation metal sheath and high grade steatite insulators to withstand high temperatures. A superior grade NiCr resistance wire coil provides uniform and reliable heat distribution with the best combination of physical strength, high emissivity & good thermal conductivity to heat cylindrical parts, good for sheath temperature up to 5000C. PHP Ceramic Band Heaters are also available with various construction styles with special inbuilt Energy saving options.

Features:

  1. Available in Chrome Nickel Steel with Power Saving Options.
  2. Special High Grade Steatite Insulators for Superior Thermal Conductivity.
  3. Power saving up to 30%.
  4. Designed for Higher Temperature up to 500°C.
  5. Robust Terminal Junction with Specially Designed Protection Cap.
  6. Efficient Heat Transfer even on irregular surfaces in comparison to Mica Band.
  7. Conserves Energy with Improved Heating Efficiency up to 55 Watts per square inch.
  8. Engineered for Longer life with Superior quality Nichrome wire for Uniform Temperature & Maximum Amperage carrying capacity.
  9. Reduces Down time for replacements.
  10. Easy installation and removal.
  11. Available in various Lead Terminations & Clampings expandable to fit around the Barrel O.D.

Applications:

  1. Injection Moulding.
  2. Film extruders.
  3. Blow Moulding.
  4. Plastic & Rubber Processing Machinery.
  5. Laboratory Equipment

3 Construction Styles :

1. Premium-Heat Construction

2. Power Saver Construction

Electrical Variations:

Single Phase: Band heaters are usually designed on 230 Volts single phase unless specified.

Dual Phase: Ceramic Band Heaters can be designed with multiple circuits to operate in single or three-phase circuits.

Three Phase: On very high wattage band heaters it would be advantageous to install three-phase wiring to reduce the current load across a single conductor. Three-Phase wiring is available with all types of insulation, Construction styles, and clamping variations.

Limitations: Minimum width: 3"(76.2mm).
