RPT (Reduced Pressure Test) Unit

The Reduced Pressure Test (RPT) Machine is used to evaluate the hydrogen content and metal cleanliness of molten aluminium. By solidifying a metal sample under vacuum, it helps foundries assess porosity levels and optimize the degassing process for superior casting quality.

Description

Key Features

  • Relay-based operation for reliable performance
  • Fixed vacuum pressure range of -600 to -750 mmHg
  • Stainless steel vacuum chamber
  • Digital timer for accurate test duration
  • Vacuum pressure gauge with mmHg display
  • Heavy-duty ½ HP vacuum pump with low-noise operation
  • Dual sample holder for increased testing efficiency
  • Stainless steel sample cups (1.5–2 mm thickness)
  • Operates on single-phase 220–240 V, 50 Hz power supply
  • Designed for rugged foundry environments

Benefits

  • Quickly evaluates hydrogen content in molten aluminium
  • Detects gas porosity before casting
  • Verifies degassing process effectiveness
  • Improves casting quality and reduces rejection rates
