Advanced Heating Technology

The PT4 Series is engineered utilizing Metcal's proprietary Resistive Radiant Heat Technology. This system employs a ceramic plate that effectively radiates heat through a tempered glass surface, ensuring an even thermal distribution across the heating zones. This unique design alleviates the risk of hot spots, promoting consistent thermal performance that is essential, particularly in demanding applications.

Precision and Flexibility

One of the standout features of the PT4 Preheaters is their ability to provide heating to four independent temperature zones. This innovative design allows users to manage various circuit board sizes and complexities, thereby providing enhanced operational flexibility. Temperature regulation is conducted through external thermocouples, which continuously monitor and adjust heat levels in real-time. Advanced temperature control modes, along with customizable programmable profiles, ensure that temperature requirements for specific circuit boards are met with precision and reliability.

Curtis Yamauchi, Senior Product Manager at Metcal, commented, "At Metcal, our focus remains on two pivotal elements crucial to any industrial operation: process control and precision. The PT4 Series Preheaters are designed to deliver the high performance and precision controls that our customers have come to expect from Metcal."
