Calorifiers
- Description
- This type of plant is generally used in certain hot water systems. They are used to transfer heat from one medium to another without them mixing. Often referred to as heat exchangers. May be steam or hot water heated.
- Periodicity of Inspection
- 26 months
- Why Inspect It
- The main hazard with this type of plant is that the vessel may fail because its safe working pressure has been exceeded or because its ability to withstand pressure has been reduced through in-service degradation e.g. corrosion or fatigue.
