Maltec-H FP range of cast aluminium line heaters provide a compact and efficient heating solution for constant flow liquids or gases. The design incorporates electric heating elements and an indirect process heating coil embedded within marine grade cast aluminium. This provides excellent heat transfer properties combined with low surface temperatures. Cast heaters are increasingly being selected over traditional pressure vessel type heaters for the following reasons:


  • Cost effective
  • Uniform heat distribution
  • Available on shorter lead times
  • Resistant to any internal vibrations
  • Compact size with a reduced footprint
  • Increased safety due to the encasement
  • Suitable for high process design pressures
  • High reliability and increased service life
  • Excellent heat transfer and residual heating from the aluminium casting

Typical Applications

  • Natural gas
  • Paint heating
  • CO2
  • Instrument air
  • Pasteurisation
  • Air
  • Steam generation
  • Nitrogen
  • Solvent
  • Annealing
