Gas-Dry Online Moisture Removal

Meet your new hero EMT Gas-Dry: defending your GIE from moisture 24/7.

The Simple, No-Outage Solution to Moisture in Gas-Insulated Equipment.

Moisture is one of the leading causes of fault escalation in gas-insulated circuit breakers and switchgear. EMT Gas-Dry is a passive, non-invasive moisture removal module engineered to safely reduce water content in SF6 and Dry Air insulated equipment — without de-energising the asset and without using bulky gas carts.

No outages
No vacuuming

EMT Gas-Dry connects directly to your filling port and begins working immediately — while equipment remains in service. The unit is pre-pressurised to protect asset pressure stability and uses a high-performance desiccant system to absorb moisture efficiently and safely.

• Non-invasive drying technology – no need to de-energise or use gas carts
• Simple on-site maintenance – just change the desiccant and continue the process
• Pre-pressurised – to prevent pressure drops upon connection
• Customisable – choose from small or large compartments for ultimate flexibility
• No outages – keep your equipment running without the hassle of downtime
• Extended equipment life – minimise breakdowns and faults caused by moisture contamination
• Trackable maintenance – cloud management system coming in late 2026 to send automated desiccant change alerts and record moisture readings before and after Gas-Dry deployment
• Cost-effective – a low-cost solution to an industry-wide problem

Traditional Gas Cart Method	EMT Gas-Dry
Requires outage	No outage required
Gas removal & vacuuming	No gas removal

Does Gas-Dry require de-energisation? – No. It is designed for online deployment.

Will it reduce system pressure? – No. It is pre-pressurised to maintain asset pressure stability.

How long does drying take? – Drying time depends on:

Initial moisture content
Compartment volume
Gas type

Is it reusable? – Yes. Replace the desiccant and redeploy.
