Annealing machine for electric heater or heating elements

The TOPE Spot Annealing Machine is designed to quickly and efficiently anneal either particular sections of elements or their entire length after they have been reduced.

Unlike other annealing machines that use time-based controls, our machine is not affected by variations in tube materials or tube wall thickness. The preset temperature can be changed quickly. The machine can accommodate different element lengths by manually moving the carriages and the eject hangers.

The elements are hand-loaded into the machine and automatically unloaded if the element length is short enough to be ejected. If the element length is over the eject length, the element must be manually unloaded. The following chart gives some typical annealing times for specific elements.

*fast and inexpensive method for annealing your elements
*element length or diameter change takes less than 5 minutes
*infrared sensor is used to accurately control the annealing temperature
*can be used to anneal portions of the element or the entire length
*transformer, cables, and electrodes are water-cooled
