FGDS Aspirator Systems FGDS-ASP1000
INTRODUCTION
Aspirator systems are used to detect Flammable Gas, Toxic Gas & Smoke in applications which are not suitable for point detection.
FGDS manufacture gas aspirator systems for use in hazardous areas and provide custom built solutions for a wide variety of applications including offshore oil and gas, petrochemical, chemical, and refining industries.
Our aspirators are engineered to allow ease of maintenance and utilise whenever possible standard components, these systems can be supplied with any manufacturer’s gas or smoke detector, fully certified and constructed in accordance with ATEX regulations.
Features:
Applications include monitoring for:
APPLICATION
Aspirators (sampling systems) provide a solution to the complex problem of accurately monitoring gas and/or smoke ingress into areas where it is not practical, possible or safe to position a detector directly, and even where there is no instrument air.
FGDS Aspirator Systems can be used with any manufacturer’s gas or smoke detection products. Each aspirator cabinet is custom built using our own design “Aspirating Block” and other standard component parts.
Combustible and toxic gas as well as smoke detectors can be mixed in one cabinet.
Self-Compensating Duct Probes can be supplied providing an accurate representation of any duct being monitored.
ASPIRATOR SYSTEM PRINCIPLE
The Aspirator systems are made from components engineered by FGDS to meet the requirements of the application to proven specifications, the systems can accommodate Flammable, Toxic/Oxygen Gas Detectors and smoke detector all on a single loop.
Self-compensation and back purgeable Duct Probes are supplied to withdraw an accurate sample of the target gas to be monitored, the sample being measured is pulled under a vacuum created by an air driven pump (Eductor).
Flow rates are controlled by an integral needle valve with the velocity being indicated on a flow meter, the sample is passed across the sensor and then exhausted, along with instrument air, via the exhaust port.
Sample lines can be cleared by pressing the line purge button, diverting instrument air down the sample line.
Calibration of the gas sensor is carried out via a failsafe valve and a quick connect coupling.
