Wenesco Preheaters
Models PMX 1212, Special Preheater 6" x 2" Heated Area
Wenesco Models PMX 1212 and the Special Preheater with 6″ x 2″ heated area are designed for controlled PCB and electronic assembly preheating in demanding production environments.
These industrial preheaters support retrofit integration into existing wave solder systems, replacement of older preheaters, or standalone bench-top operation for precision thermal processing applications.
PowerMax preheaters utilize high-output radiant heating elements capable of transferring heat to a target positioned one inch above the heating surface at rates up to 3°C per second.
Each unit includes a precision digital thermostat with current temperature and set-point display, a 25°C to 300°C operating range, illuminated power switch, fuse protection, and a standard 5-foot line cord for reliable and repeatable industrial heating performance.
Wenesco welcomes your inquiry regarding other sizes and shapes.

Special PreheatersÂ
Wenesco custom special preheaters are engineered for specialized thermal processing applications requiring targeted heat delivery and application-specific heating configurations.
Custom square, rectangular, or round nozzles can direct heat to selected PCB areas or components, improving process control and thermal efficiency during production operations.
Wenesco can also design adjustable or fixed PCB holding fixtures to maintain accurate positioning over the heating zone for repeatable processing results.
These custom preheating systems are well suited for electronics manufacturing, PCB assembly, laboratory environments, and other industrial applications where standard heating equipment does not meet operational requirements.
