• Small and compact
• Fully adjustable speed
• Automatic shut-off when carbon brushes reach their wear limit to avoid expensive armature damages
• Built-in electronics provide superior temperature control and heating element protection
• Can be used in the most confined spaces
• Closed-loop temperature control (TRIAC DRIVE AT only)​
