C011032 Xgard Safe Area ESU for Three Detectors by Crowcon

The Environmental Sampling Unit provides a cost-effective solution for monitoring high-density gases such as chlorine, sulphur dioxide and flammable vapours, in environments where the positioning of conventional sensors is not practical.

The sampling chamber is fitted with an electric fan, which draws an air sample via a pipe. Xgard gas detectors are fitted to the chamber to monitor for the presence of flammable or toxic gases.

Features:

• Can monitor up to 12 metres of perforated pipe using a fan-aspirated single sensor.
• Flameproof fan available for flammable gas applications.
• Fan-fail monitoring is available for up to four units using a Gasmaster control panel.
• Typical applications include gas detection in LPG and chlorine stores, flammable gas detection in wet wells.

MA1138 86ASU (Fire) Sampling Unit - for Series 60 Fire Detectors by Crowcon

The Air Sampling Unit (ASU) is designed to be used with Crowcon s Xgard range of detectors for monitoring potentially hazardous gases within ventilation ducts.

Features:

• Enables air ducts to be monitored without requiring the detector to be mounted within the duct.
• Avoid sensor drift due to air-flow effects.
• Simple, easy to install design.
• Simple detector maintenance: there is no need to access the duct for calibration purposes.
• Extremely reliable; ASU has no moving parts.
