ADVANTAGES OF INDIRECT HEATING
- Better thermal control secures gentle handling of the thermoplastic material. This ensures optimal application conditions in the temperature working area – maximum heating without risk of material damage
- Safe heating conditions via the uniform heat distribution from the thermal oil
- Uniform storage temperature in all parts of the preheater – no hot spots
- Longer lifetime of the preheater due to the more gentle heat supply from the burner – no overheating of the steel parts
ADVANTAGES OF DIRECT HEATING
- Quick heating time due to the burner only needing to heat the steel of the preheater – no thermal oil as an in-between medium
- Higher melting capacity due to more effect heating in the preheater, which then heats and melts the thermoplastic
- Simple construction – no thermal oil reservoir is build into the construction
- Lower cost price due to the more simple construction
