BARTEC HYGROPHIL HCDT 5673 Hydrocarbon Dew Point Analyzer 5985-72
Description
Product Overview
The BARTEC HYGROPHIL HCDT 5673 analyzer is a hydrocarbon dew-point instrument based on the chilled mirror principle, designed for continuous measurement of hydrocarbon dew point in natural gas and other hydrocarbon gas streams. The instrument is part of the Hygrophil HCDT series of measuring systems for gas quality monitoring.
The analyzer uses an optical chilled mirror sensor that cools a mirror surface until condensation of hydrocarbons is detected, providing a direct physical measurement of the dew point. The system includes a sensor housing (type HCDT-5673 sensor) and the SCS 5985-72 analyzer unit, which controls the measurement and provides the outputs.
Key Features
- Chilled mirror hydrocarbon dew-point measurement for natural gas
- Direct physical measurement principle with optical detection
- Calibrated range: -20 C to +5 C dew point
- Cooling capacity down to 35 K below ambient
- Three analog 4-20 mA outputs for process integration
- Fully automatic measurement cycle
- Proven BARTEC gas quality technology

Ordering and Selection
When selecting the BARTEC Hygrophil HCDT analyzer, confirm the sensor housing, cooling capacity and output configuration, because each Hygrophil HCDT analyzer is built for a specific gas quality monitoring duty. The HCDT 5673 version includes the chilled mirror sensor system, and the selected Hygrophil HCDT must be matched to the gas pressure and dew-point range at your station. Our team can help you confirm that the Hygrophil HCDT analyzer you select is correct for your natural gas application.

Installation and Sample Conditioning
A chilled-mirror measurement is only as good as the sample delivered to the sensor. The sample take-off should be located on a representative part of the pipeline, with a short line that is heated or insulated where needed to prevent condensation before the sensor. Filters should remove particles and liquid carry-over without stripping heavier hydrocarbons from the gas, and pressure regulation must match the pressure at which the dew point is to be reported. Installing the sensor housing and analyzer unit in a ventilated analyzer shelter protects the electronics from direct sun and high ambient temperatures, which also helps the cooling system reach the required mirror temperature.
Commissioning Checklist
- Confirm sample pressure, flow and line heating against the design values
- Check that the mirror is clean and that the optical detection responds correctly during the first measurement cycles
- Verify the three 4-20 mA outputs against the values shown locally and in the station control or gas quality system
- Record the first stable dew-point results as a reference for later comparison
Maintenance and Troubleshooting
Routine work on the BARTEC HYGROPHIL HCDT 5673 analyzer centres on the mirror and the sample path. A contaminated mirror, for example from glycol, compressor oil or particulate carry-over, can shift the detected condensation point, so inspection and cleaning intervals should follow site experience with the gas quality. If readings become unstable or do not follow expected trends, check filters, regulators and line heating first, then the mirror condition, before suspecting the electronics. If the mirror cannot reach the expected temperature on hot days, the required cooling below ambient may be beyond the available margin, and improving shelter conditions is often the practical fix.
Gas Quality Monitoring in Oman and the GCC
Hydrocarbon dew point is a key parameter in gas sales agreements and pipeline entry specifications across the region. Gas processing plants, transmission networks and power stations that receive pipeline gas use continuous dew-point data to confirm that liquids will not drop out in the network and damage downstream equipment such as gas turbines and metering skids.
Supply and Support
Seven Star LLC supplies the Hygrophil HCDT series and related spares for gas quality systems in Oman and the GCC. Provide the full model code from the nameplate, the gas composition and the operating pressure, and our team will help confirm the configuration and spare parts list for your station.

About brand
BARTEC is a German specialist in explosion protection: electrical equipment, control systems, heating, analysers and mobile computing for hazardous areas. Reinhold A. Barlian founded the company as a one-man business on 17 January 1975 in Bad Mergentheim, where the group is still headquartered; his first product was a safety switch to prevent explosions at petrol stations. Today BARTEC describes itself as a world market leader in explosion protection.
Seven Star LLC is an independent supplier listing BARTEC explosion-protected enclosures, control stations, components, mobile devices and BARTEC BENKE process analysers for buyers in Oman and the GCC. Items are matched from the order number and the Ex marking on the nameplate.
