SS 304 Sheathing with 4mm thick Heat saving Thermal insulation.
Single Piece Construction.
500 mm long Insulated Metal Braided Flexible Leads. Allen Key Barrel Nut clamping with Terminal Protection Box.
Total wall thickness 12mm Min Requirement : I.D. 60mm width 35mm

Premium Heat Construction

Standard Feature for all PREMIUM HEAT Ceramic Heater bands:

1. Stainless Steel (304) sheathing.
   Stainless Steel housing with serrated edges provides maximum flexibility for ease of installation.
   
   

2. Thermal insulation
   Built-In heat saving Thermal Insulation standard (4mm) on all Ceramic Bands -"Premium Heat" will reduce power consumption. Further reduction can be obtained with higher thickness insulation which prevents heat loss, thereby lowering energy costs.
   
   

3. High Grade Ceramic Insulators.
   Interlocking Steatite bricks designed for best combination of physical & dielectric strength, good thermal conductivity to heat cylindrical parts, good for sheath temperature upto 650 Deg C. provides flexibility for ease of installation on the barrel.
   
   

4. Ni-chrome Heating coil.
   Helically wound superior quality ( 60/16 , 80/20 ) Nickel-Chrome resistance wire designed for maximum current carrying capacity is strung through specially designed ceramic insulating bricks providing even heat distribution, thus eliminating hot spotting that can cause premature heater failure.

Suggested Watt Density 40 to 45 Watts / Sq Inch.

Power Saver Construction

1. Stainless Steel (304) sheathing.
   Stainless Steel housing with serrated edges provides maximum flexibility for ease of installation.
   
   
2. Thermal insulation
   In addition to the Built-In 4mm thick heat saving insulation an extra 12mm thick flexible insulation is affixed on the external sheath to reduce power consumption. Further reduction can be obtained by using "POWER SAVER PLUS"
   
   
3. High Grade Ceramic Insulators.
   Interlocking Steatite bricks designed for best combination of physical & dielectric strength, good thermal conductivity to heat cylindrical parts, good for sheath temperature upto 650 Deg C. provides flexibility for ease of installation on the barrel.
   
   
4. Nickel-chrome heating coil
   Helically wound Nickel-Chrome resistance wire designed for maximum current carrying capacity is strung through specially designed ceramic insulating bricks providing even heat distribution, thus eliminating hot spotting that can cause premature heater failure.

PHP has engineered an Robust Design to meet the increasing demand for Improved Heating Efficiency, Faster Productivity and at the same time Conserve Energy by Reducing Power Consumption, Based on the principle of radiation, conduction & convection this exclusive design comes with an Additional External HEAT OPTIMIZING Thermal Insulation apart from the Standard built in 4mm thick Insulation.. The heat generated will remain inside the gap between the heater and the Additional insulation (as shown in sketch) which not only helps conserves energy up to 30% and MORE but also helps minimize heat dissipation & lowers the external sheath temp by 60-70% dramatically improving the working atmosphere. For eg ; If the Inside surface temp is appx 280 deg C then the outer Sheath Temp will be appx 95 Deg C. in comparison to other Ceramic Heater Bands.

Suggested Watt Density 50 to 55 Watts / Sq Inch.
SS 304 Sheathed with Heat Optimizing Insulated Cover
Single Piece Construction
500 mm long insulated Metal Braided Flexible Leads Allen Key Barrel Nut clamping with Terminal Protection Box
Total Wall thickness : 45mm (12mm + 38mm Insulation) Min requirement : I.D. : 100mm, Width 75mm

Standard Feature for all "Power saver PLUS" Ceramic Heater bands:

1. Stainless Steel (304) sheathing.
   Stainless Steel inner housing as well as External Insulated housing with serrated edges provides maximum flexibility for ease of installation.
   
   

2. Additional Heat Optimizing Thermal insulation :
   Apart from the in built 4mm Insulation A Special Additional HEAT OPTIMIZING Thermal Insulation (16mm ) along with an AIR POCKET which preserves the heat inside producing a uniform hot air layer between the Heater & the outer Insulation ( as shown in sketch above) This helps reduce power consumption upto 30% AND MORE (subject to working conditions) & prevents heat loss thereby lowering energy costs, improves Heating Efficiency for faster productivity and simultaneously also helps improve working atmosphere.
   
   

3. High Grade Ceramic Insulators.
   Interlocking Steatite bricks designed for best combination of physical & dielectric strength, good thermal conductivity to heat cylindrical parts, good for sheath temperature upto 650 Deg C. provides flexibility for ease of installation on the barrel.
   
   

4. Nickel-chrome heating coil -
   Helically wound Nickel-Chrome resistance wire designed for maximum current carrying capacity is strung through specially Designed ceramic insulating bricks providing even heat distribution, thus eliminating hot spotting that can cause premature heater failure.
