Preheating, stabilising and vaporising liquids for analysis
GO vaporizing regulators are designed to prepare liquids and gases before analysis or processing: samples can be preheated, gases kept free of condensation, and liquids fully vaporised. Ideal for analytical instrumentation, gas samples, petrochemicals, LNG, pipeline sampling, and high-purity / specialty gas lines.
By combining a heat exchanger and a pressure regulator, these units offer both temperature and pressure control in one compact, safe and easy-to-maintain module.
Why GO vaporizing regulators?
- Heating or vaporising liquids before gas analysis
- Preventing condensation of gases
- Stable pressure and temperature control, even with changing inlet conditions
- Modular design: heat exchanger + regulator, easy maintenance and configuration
- Suitable for process, petrochemical, LNG, high-purity and laboratory applications
Overview of types
- Modular construction: heat exchanger and pressure control section are separate, making maintenance, cleaning or seat replacement easier.
- Spiral-wound heat exchanger: ensures efficient heat transfer and uniform heating; prevents cold zones and condensation.
- Wide temperature range: up to approx. 193–285 °C (depending on model and version).
- Certification & safety: ATEX / CSA certified, flame path classification, option of a thermal cut-out (TCO) for extra safety on electrically heated units.
- Flexible power options: electric versions in 120 VAC or 240 VAC; steam-heated versions are available for steam or process applications.
Applications of GO vaporizing regulators
GO vaporizing regulators are used to vaporise liquids, keep gases free of condensation and preheat samples before they enter an analysis or process installation. This makes them essential in environments where accurate sample composition and stable analysis conditions are crucial.
1. Analytical instrumentation
- Gas chromatography (GC)
- Mass spectrometry (MS)
- FTIR, NDIR and other online gas analysers
- Continuous emission monitoring (CEMS)
- Sample conditioning for analyser houses
Why:
Condensation, too low a temperature or residual liquids disrupt analysis methods. A vaporiser makes the sample stable and reproducible.
2. Petrochemical & chemical industry
- Vaporising liquids in process systems
- Stabilising hydrocarbon samples
- Conditioning of VOCs
- Inline samples for refinery analyses
- Gas sampling on pipelines
Why:
Heavy hydrocarbons or liquid/gas mixtures must be fully vaporised to obtain correct readings.
3. Cryogenic & LNG applications
- LNG preheating during sampling
- Vaporising cryogenic mixtures
- LNG-to-gas conversion for instrumentation
Why:
Temperature stability is crucial here to control phase change.
4. Sampling and monitoring processes
- Flare gas monitoring
- Stack gas sampling
- VOC control
- System diagnostics and emission measurements
- Process gas recirculation
5. High-purity & specialty gas
- Condition monitoring for corrosive or reactive gases
- Vaporising specialised liquid precursors
- Semiconductor / cleanroom gas conditioning
6. Laboratories & research environments
- Test setups where temperature and pressure must be controlled
- Experimental chemistry and liquid vaporisation
- Research into volatile components
