Vacuum Calibration Tank | Single & Double Chamber Cooling & Sizing for PVC/HDPE/PPR Pipe Extrusion Lines

Vacuum Calibration Tank – Precision Cooling & Sizing for Pipe Extrusion Lines

Our Vacuum Calibration Tank is engineered for high‑speed plastic pipe extrusion, delivering accurate sizing, uniform wall thickness, and a smooth surface finish. Available in single‑ or double‑chamber configurations, it integrates VFD‑controlled vacuum (energy‑saving), a patented automatic water level control, and a centralized water supply with optimized nozzle layout. Built from stainless steel, it reliably cools and calibrates PVC, HDPE, PPR, and PE pipes from 16mm up to 1200mm diameter. Reduce energy costs, minimize scrap, and achieve consistent quality – line after line.
