USE


The flexible GM.56 insulation system is designed to minimize heat loss effectively, resulting in significant reductions in energy costs.

It delivers exceptional performance when applied to heated cylinders in injection molding and extrusion processes, with average energy savings of 20-40%. Additionally, the system reduces the heat emitted into the surrounding environment, keeping ambient air cooler.

By lowering surface temperatures by 60-75%, GM.56 Insulation covers also enhances workplace safety, providing operators with a safer and more comfortable working environment.

CONSTRUCTION


Custom insulating covers can be manufactured to fit individual band heaters or cover the entire cylinder of a machine. These covers are designed to accommodate specific electrical connections and sensor configurations, ensuring seamless integration.

Engineered with a multi-layered construction featuring high-temperature stability, these insulating covers effectively reduce surface temperatures. This innovative design minimizes energy loss, significantly improving thermal efficiency and reducing operational costs.

ADVANTAGES


 
 
  • It reduces 20-40% energy consumption of the machine heaters
  • Extended life of the heaters because of less on and off cycles
  • Increased protection by reduction of the surface contact temperature by 60-75%
  • It can always be retro-fitted rapid assembly and disassembly
  • Amortisation time of HEATSAVE is less then 1 year
  • Non-inflammable
  • Reduction ot the „start-up“ time
  • Custom made
  • Impovement of room temperature, becauseheaters radiate much less heat (Very important in summer months)
  • Even temperature profile of the machine-cylinder
