First bought samples for lab validation, then placed 800pcs order for resale to local industrial customers. This corrugated aluminum PTC heating element has excellent self‑limiting temperature feature, overheat protection works well under continuous running. Heat dissipation performance is better than other suppliers we tried. Customer feedback is positive, already arranging repeat purchase.

We ordered 1200 pcs corrugated aluminum PTC heating elements for our industrial heating equipment. Self‑limiting temperature function works reliably, built‑in overheat protection gives us extra safety guarantee. The corrugated aluminum structure brings good heat dissipation. Batch consistency is good, mass production delivery was on time. We will re‑order for our new project.

Received 600pcs PTC heating elements after sample testing. Self‑temperature‑limiting performance meets our industrial application requirements. Overheat protection triggers as expected. The only suggestion is that the wire terminals could be more diversified for different assembly ways. Overall satisfied with this supplier. 评论人： Luis Herrera
