Technical characteristics of tubular heaters

  • High load capacity
  • High degree of operational safety, because
    of no contact with live parts and components
  • Moisture protection
  • Superior capacity-to-space ratio
  • High temperatures
  • Excellent heat transmission
  • Shock and vibration proof
  • Very rugged and durable
