All the highlights and headlines from EMT USA

The team are back at EMT HQ following a busy schedule in Florida last week.

All the highlights and headlines from EMT USA to follow:


New EMT office in Florida officially opens its doors to deliver service and support to US customers


EMT CEO Neil Kane, visited the new facility in Fort Lauderdale and was pleased to see US operations well underway. In addition to a sales and rentals hub, the site provides a service and calibration centre for customer equipment, providing valuable service and support for our US customers. This significant development was well received by visitors to the EMT booth at PowerTest.


Address details can be found on our homepage.



Rep conference proves very promising for the future success of EMT US operations


Having recently signed exclusive agreements with several experienced and professional US manufacturers’ representatives for our world class SF6 and Eco gas management solutions, the EMT senior management team led a conference for new appointments, which proved beneficial for all parties. A packed itinerary was delivered by VP Global Sales & Technical Services Neil Gwinnutt, which included live demonstrations and product training. The meeting was very positive and we are confident that these collaborations with established distributors, reputed for delivering premier products, will be dedicated to serving EMT customers in the Utility Substation, Transmission, Distribution and Generation industry.


Contact us for your local representative.

If you would like to join our US rep network please get in touch.



PowerTest 2023 delivers for EMT


The event was a huge success and delivered on so many levels. Proceedings kicked off with a presentation at the New Product Forum on EMT’s new multi-application SF6 & Eco gas solutions range, spearheaded by the world’s first 4in1 SF6 & Eco Gas Analyser, the Zerowaste Eco+.


This followed the next day by live product demos of our latest technologies for insulating gas analysis and handling, where the theme at the EMT booth was very much on future proofing insulating gas management equipment. There was a hive of activity with notable interest in the new Leak Hunter Dual SF6 & Eco Gas Portable Leak Detector, which generated a number of enquiries, given its appeal for addressing a major problem facing utility companies; one simple, portable instrument can perform two jobs efficiently and effectively, rapidly detecting leaks on GIS, switchgear and gas insulated compartments containing SF6 or Eco based insulating gases.


The EMT Moisture Pro also proved popular for its portability and smart features, with a number of utilities interested in adding the unit to their equipment inventory for fast, reliable and accurate moisture determination of their dry air, SF6 and alternative gas assets.


Another new concept creating a buzz at the show was the SmartMix Automated Gas Mixing System, which generated much discussion around the handling, mixing and control of gas, leading to several requests for custom projects by the EMT Engineering division.

EMT News Gas Monitoring and Safety

Monitoring and Safety Solutions for SF6 and Eco Gas Applications

EMT’s comprehensive and growing portfolio of insulating gas management solutions includes a range of portable and fixed monitoring and gas detection systems, to ensure the safety and protection of personnel and assets, whilst meeting global compliance standards.


EMT Smartfill CTU

Designed for managing leakage of SF6 from circuit breakers and other plant, Smartfill CTU is a unique SF6 ‘live topping up’ leak management device, which provides 24/7 monitoring and automated continuous top-up of leaking assets, dosing gas as required with no waste and no leakage. This smart system enables operators to start top up remotely; records cylinder pressure to eliminate downtime from empty cylinders; and alerts engineers of any issues via SMS. Smartfill technology reduces SF6 usage, costs and inventory, provides transparency for legislative reporting, and ensures business continuity.


EMT Pressure Validation Kit

Designed to deliver fast, simple, accurate pressure gauge verification, EMT DPG solves the problem of inaccurate or out of calibration equipment pressure gauges. Supplied in kit format with fittings and hose for easy connection to asset test points, this essential tool provides engineers with an accurate NIST traceable (ISO 17025) pressure reading and is Eco gas ready.


Personnel Gas Safety Monitors

Operating companies have a duty of care to employees to protect them in the workplace from substances hazardous to health and are legally bound by Workplace Exposure Limits (WEL) on SF6, alternative gases and their by-products. EMT offer a range of portable and fixed, personal and area gas safety monitors to protect personnel in hazardous areas such as indoor cylinder stores and confined spaces. From single to multi-gas detection, team protection and area monitoring, these critical devices provide low cost, low maintenance, effective solutions to ensure safety when working with SF6, Novec, Dry Air, and breakdown gases.


EMT Site Services

Our Site Services team can provide a range of hire equipment to clients with urgent or short-term instrumentation requirements, including lease of the Smartfill CTU for 24/7 SF6 gas monitoring and leak management. This smart solution negates engineer call outs, the challenges of scheduling engineers for repeated visits to site to top up leaking assets, and the associated costs of managing this.

SF6 site survey, flange repair, leak management – job done with EMT Site Services

They say pictures speak a thousand words; here’s our latest Site Services project completed for a UK electric utility. Following a site survey, the team confirmed SF6 leaks on all phases of the asset, which required immediate repair and preventative maintenance. The project was for x6 flange repairs; x3 upper flange and x3 lower cover plate with sensor. All repairs were carried out under live conditions and full pressure. From surface preparations; to soft shell mounting and reinforcement; through to hard shell, resin application, final seal and post repair testing – our expert engineers followed proven and rigorous EMT protocols using trusted and reliable EMT technologies and solutions, to ensure compliance at every stage of the project.

EMT News SF6 Gas Handling

Products and services expertly developed for best practice SF6 gas handling

Driven by regulation and standards on SF6 emissions, the energy industry is moving forward with strategies for carbon neutrality and the collection, treatment and recycling of SF6 gas. IEC and CIGRE guidelines specify a number of gas handling requirements when performing key tasks within SF6 operations and process control. Key to which, is monitoring and recording SF6 passing through the network; operators must understand how much SF6 has been used, lost, and replenished. Effective maintenance procedures, transparency and accuracy of data are all critical to meeting legislation.


EMT specialise in insulating gas management, delivering products and services expertly developed for best practice SF6 gas handling. Our range includes everything from advanced technologies for SF6 filling and topping up, nameplate verification, gas carts and pump systems; to fittings and accessories designed to ensure a more efficient fill during maintenance tasks; and onsite client support services including degassing, top-ups, gas replacement and regeneration.
