SELECTION


Choosing the right band heater for your application is crucial to ensure optimal performance, energy efficiency, and longevity of your heating system.

Here are key factors to consider when selecting a heater band:
  • Temperature Range: Determine the maximum operating temperatures required for your process.
     
  • Watt Density: Assess the power requirements to achieve the desired heating levels efficiently. Higher watt densities are suitable for faster heating and more demanding applications.
For applications requiring heating elements on surfaces with diameters larger than 400 mm, we recommend using multiple segments of heating elements connected together with clamps.
 

FREQUENTLY ASKED QUESTIONS

When to select Micanite Insulated Band heater GM.50
Select Micanite when working temperature is under 350°C and when you need max 4 W/cm2. Production time is faster for micanite band heater and therefore have more interesting price.
When to select Micanite Band heater with heat transfer plate GM.52
Select Band heater GM.52 when you have multiple holes and you need to improve Heat distribution  and enhance  Thermal Conductivity across cylinder. Heat transfer plate provides additional protection of heater element from surface to the heater.  Max working temperature up to 350°C.
When to select Micanite Band heater INSIDE/OUT GM.53
Select Band heater GM.53 when you need to heat cylider from inside out and when working temperature is under 350°C and when you need max 4 W/cm2.
