Optimal consistency and quality

• The rolling induction system eliminates the inconsistencies and quality issues associated with open-flame-torch heating methods
• Temperature measurement allows operators to set and achieve targeted preheat temperatures easily with limited button pushing
• The travel detect system prevents hot spots by controlling output based on travel speeds and turning output off if the part is not moving

Improved safety

• Eliminates open flames, reducing burn as well as fumes and explosive gas hazards
• Direct heat transfer results in cooler shop environment that reduces operator fatigue and improves work conditions

Maximum productivity

• Quick time to temperature increases production efficiencies while reducing consumable costs and labor expenses
• Heating while rolling the pipe assembly allows for continuous fabrication
• Compact and portable to configure around various pipe sizes throughout the fabrication shop
