1. Unexpected Downtime: Poor insulation leads to overheating, causing up to 30% more unplanned shutdowns in a year.
2. Hidden Energy Loss: Low‑efficiency cores waste up to 15% more electricity, inflating operating costs.
3. Compliance Risks: Non‑certified units can fail CE, UL, or FCC audits, exposing you to fines and shipment delays.
4. Long Lead Times: Inconsistent manufacturing often forces re‑orders, extending project timelines by 3‑6 months.
5. Limited Customization: Off‑the‑shelf models rarely match your voltage‑regulation or footprint requirements.
