SWG100 BIOEX - Fixed Gas Analyser ATEX certified

Description

The SWG100 BIOEX is the NEW generation of fixed gas analysers which provide continuous monitor of 02%, CO2%, CH4%, H2S, H2 and CO gases primarily in Biogas generated from AD (Anaerobic digestion) and Waste water treatment plants, landfill gas and bio-methane upgrade plants.

ATEX and UKEX Certifications

The SWG100 BIOEX is ATEX (2014/34/EU) and UKEX ( UKSI 2016:1107) certified for use/installation in ZONE II –

EX II 3G ec nC IIC T6 Gc ( with-out internal heater)

EX II 3G db ec nC T4/T3 ( with internal heater)

Built-in Gas Cooler

The SWG100 BIOEX integrated gas cooler, along with the peristaltic pump and the AUTO CAL functions provide high accuracy, repeatable and stable readings in any process conditions even with extreme wet gases, such has biogas sampling before the heating treatment. The employment of the gas cooler also maximise sensors protection from moisture build-up in the gas stream.

H2S Innovative Dilution system 50:1

The optional dilution system installed on the H2S channel is proven to be essential in many applications where H2S can fluctuate from very low ppm to very high concentration. This innovative system allow to continuously measure H2S in any process condition whilst protecting the sensor from sudden rise of H2S levels. Typical applications include sampling before and after the scrubbing using a multi-sample point gas analyser.

Data logging and Industrial Interfaces

Measured data are displayed on its large colour display and automatically logged to the internal SD card with user definable interval period. Data outputs are available via Modbus RTU, 4-20 mA analogue outputs ( up to 40 individually configurable) and most of the common industrial interfaces such us Profbus, Ethernet and Profinet.
In addition to all this, the SWG100 BIOEX can provide up to 20 alarm relay outputs, fully configurable, which are trig by a user define above/below value. Typical application include CHP’s engines Oxygen trip/protection.

Robust and Easy to service

The SWG100 BIOEX design build incorporates an IP 65 rated stainless steel enclosure, extreme easy installation and full on-site maintenance and easy access of all the parts. The plug and play pre-calibrated sensors technology allow the user to replace all the sensors on site in just under a couple of minutes, dramatically reducing the downtime of the gas analyser. Additional features such as the over-write available on the analogue output minimise CHP’s engine disruption in case of analyser malfunctioning.

Easy Remote firmware upgrades

Users can easly upgrade to the latest firmware release by simply download the latest firmware from our web page and upload it to the analyser via SD card.

Applications

The SWG100 BIOEX is currently installed in many sites across the UK and it is becoming the preferred choice of many Utilities Companies and landfill operators. The SWG100 BIOEX Gas Analyser main applications include:

Landfill
WWTP ( Waste Water Treatment plants)
Biogas and AD plant
Biomethane
Coal Mine ( AMM)
Gas Flaring
CHP Engine protection
