Thorne & Derrick stock and distribute heat trace cables and provide heat trace system designs for process maintenance, pipe and vessel freeze protection – this includes industrial and hazardous area approved electrical trace heating for potentially explosive atmospheres (ATEX & IECEx).

25% Sodium Bisulphite in fact is not a real compound but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulphite ions. It is a white solid with an odour of sulphur dioxide

  • Formula: NaHSO3
  • Molar Mass: 104.061 g/mol
  • Density: 1.48 g/cm3
  • Freezing Point: 0°C

Trace heating is able to heat up and maintain Sodium Bisulphite in highly corrosive atmospheres.

➡ T&D stock trace heating cables in a range of technologies including self-regulating, constant wattage, mineral insulated and parallel resistance types with international hazardous area location classifications.
