Best Practice for Gas Monitors Used in Harsh and Explosive Atmospheres

Plant technicians rigorously check for contaminants within their anaerobic digester and ensure that its performance is optimised but the maintenance of the gas analyser monitoring the whole process is often overlooked. Many analysers are used in harsh and potentially explosive environments and so it is of paramount importance that the operation runs smoothly and safely.

Companies who overlook the maintenance of their analysis equipment take on many potentially costly risks, we list a few examples of issues that can arise from non-serviced equipment: expensive unbudgeted repairs and call outs for service engineers, the loss of revenue as a result of engine downtime, potential unreliable readings affecting CH4 production, risk of rising O2 and H2S levels which  could lead to costly engine repairs, and reduced product life of the gas monitor. 

Although Geotech’s fixed gas monitor, the GA3000 PLUS is designed to be robust and reliable, due to the nature of its constant monitoring Geotech recommends yearly maintenance to avoid any costly down time.  Over the years of supporting AD and landfill sites across the globe with their gas monitoring requirements, Geotech have seen many examples of companies who ignore the maintenance of their analyser. Consequently when their process fails it often leads to a costly and lengthy down time which could have been avoided.

Important considerations when planning your site and analysis equipment: Moisture control: have you considered gas conditioning, appropriate filtration and heated gas lines to ensure moisture doesn't damage your system? Unit installation: has the installation been carefully planned?  Are you confident that the unit is installed in the appropriate location on site?  Do you have correct gas line connections? And the gases produced: what control measure do you have in place for corrosive gases? Have you considered desulphurisation?

Geotech’s technical support team and global distributor network can offer local support to help you with any of these issues.

Geotech's maintenance package was developed to help reduce the risk of unbudgeted costs for downtime on your AD plant.

The GA3000 PLUS's core sensor unit can be replaced by a spare unit whilst your unit is serviced, taking just 20 minutes to swap out, A yearly maintenance contract prevents expensive and unexpected costs. Geotech offer replacement parts which can be sent to site worldwide for quick swap out, their Technical Support team is available to offer remote fixes instead of charging costly call-out fees, they offer training and support pre and post purchase, plus they will guide you with any technical queries you have relating to how your analyser can meet your specific requirements
