Mica Band Heater

Mica band heaters provide the perfect solution for high watt densities and high operating temperature applications. Pipe heating, drum heating, barrel heating normally used for oils, lubricants or other circular applications prefer these heaters as it offers safety when heating volatile and explosive substances as well as pipes or containers that cannot otherwise be heated using direct heating.

Majorly sought for in the plastic industry, other areas where it can be installed are injection moulding machines, plastic extrudes, food industry, blow moulding machines, pharmaceutical industry and container tank and pipe heating as it provides fast heat up.

Construction

Mica Band heater

1.SS/GI Sheath for good thermal conductivity and oxidation/ corrosion resistance at elevated temperatures.

2. Mica Insulation provides excellent electrical insulation and resistant to moisture.

3.Clamping band designed to maintain clamping pressure and firm contact with the cylinder surface thus eliminating air gaps at the contact

4. Nickel-Chromium resistance strip evenly wound for uniform heat distribution and reliable accuracy

5. Terminal Box to provide protection against exposed terminals and helps guard terminals from spill over’s, dripping

6. Lead Protection is available where abrasion is a problem

7.Stainless Steelscrew terminals for maximum amperage carrying capacity and a firm connection with the winding

Termination Options

Fibreglass Lead & Stainless Steel Braid Terminations

Order Type L1/B1

T1

Leads exiting both sides of the gap is standard unless otherwise specified. High-temperature fibreglass leads are rated to 455°C. Standard lead length is 10”

Order Type L2/B2

T3

Lead wires exiting 180 degrees from the gap is common on the nozzle heater applications. 1.5” of sleeve protection is standard on lead exits.

 

Order Type L3/B3

T5

Leads exiting straight out the side is available on any construction. Leads exit through a brass eyelet

 

 

Order Type L4/B4

T2

Leads may exit at a right angle out of cap from any position on the heater. 1.5” of sleeve protection is standard

Order Type L5/B5

T4

 

Lead wires on one side of the gap are available on any construction

Order Type L6/B6

T6Stainless Steel spring provides extra support, protecting leads from sharp bends

 

Special Constructions

Two-Piece

Two-piece construction is available for easy installation and removal (Min. I.D. 3”)

Euro Plug

European type plugs are available upon request (1” x 1.75” x 1”)

Terminal Box

Terminal boxes are excellent for preventing electrical shock or electrical shorts. Terminals boxes are available on any clamping or construction style.

Expandable

Expandable Mica Heaters allow you to open the heaters to the diameters of the barrel for easy installation (Min. I.D. 3")

Holes

Band Heaters can be manufactured with custom holes or slots for thermocouples or special mounting needs. Minimum of 1/2” is required from the hole to the edge of the heater.
