Model-001 pressure reduction unit

pressure reduction unit

The Model-001 gas pressure reduction unit is designed to reduce the pressure of a gas sample from the operating pressure to a value between 0.03 and 3.5 MPa. The gas sample is simultaneously heated to prevent the possible formation of condensates as the gas cools due to the drop in pressure. The mount for a hygrometer is fully adapted to the Hygrovision-BL dew point analyzer.

Pressure reduction unit configurations

The Model-001 VMPL2.848.005 standard configuration is intended for use with a Hygrovision-BL analyzer to take measurements in automatic and manual modes under an operator's supervision.

The VMPL4.078.025 modification includes the high-pressure gas discharge set that allows for measurements to be taken in automatic on-line mode without an operator's supervision.
