Teledyne Gas & Flame Detection has introduced the PS DUO, a new portable dual-gas detector designed to improve personal safety in hazardous environments.

The compact handheld device can detect two gases simultaneously using passive diffusion sensing, and features real-time monitoring with audible, visual and vibrating alarms to alert users when gas levels exceed safe limits.

The PS DUO offers a broad selection of gas combinations including carbon monoxide (CO), hydrogen sulphide (H₂S), sulphur dioxide (SO₂), ammonia (NH₃), oxygen (O₂), hydrogen (H₂), nitrogen dioxide (NO₂), and ozone (O₃). Its ATEX/IECEx rating and 2-year warranty make it ideal for industrial settings. Users can select gas pairings tailored to their specific applications, such as H₂S and SO₂, particularly relevant in Middle Eastern operations.

The detector features a bright LCD screen displaying continuous gas concentration, wireless connectivity for easy data transfer, and internal memory capable of storing 30 alarm logs. Housed in a rugged IP67-rated rubberised casing, the PS DUO is lightweight (200g), ergonomic, and designed for comfort and ease of use in demanding environments. It runs for up to two years on a single replaceable battery.

Pawel Kulik, product manager-portables, Teledyne Gas and Flame Detection, said, “It adds to an existing and highly successful range of personal safety and gas monitoring solutions that includes our portable Protégé ZM and PS200.”

The new device complements Teledyne’s existing personal gas monitoring range, including the Protégé ZM single-gas monitor and the PS200 four-gas compliance monitor, both known for reliability and ease of use in hazardous locations.

This next-generation seal builds on John Crane’s extensive expertise in industrial sealing. (Image source: John Crane)

John Crane, a global leader in rotating equipment solutions and part of Smiths Group plc, has unveiled the Type 93AX Coaxial Separation Seal, a cutting-edge dry gas sealing solution designed to help customers reduce emissions, enhance equipment reliability, and lower operational costs.

This next-generation seal builds on John Crane’s extensive expertise in industrial sealing, offering a robust, fail-safe design that remains operational even under multiple failure scenarios.

Engineered with direct customer input, test data indicates the seal reduces nitrogen consumption by up to 80% compared to conventional radial separation seals, delivering significant efficiency and sustainability benefits.

3 ways the seal helps customers

Contamination is a major cause of dry gas seal failures, contributing significantly to unscheduled maintenance and equipment downtime.

The Type 93AX addresses this challenge by preventing oil ingress from the compressor bearing chamber, thereby minimising risks and supporting continuous, reliable operation.

According to Deloitte, unplanned downtime costs the global process industries an estimated US$50bn annually, with equipment failure accounting for 42% of such disruptions.

In energy and process applications, this translates to average losses of up to US$42mn per facility per year.

The Type 93AX mitigates these performance and financial risks by enhancing the reliability of the dry gas seal system and reducing demand on supporting infrastructure, such as nitrogen generators and air compressors.

The seal is also designed to operate effectively in three distinct scenarios, automatically adapting to failure situations to minimise disruption and contain gas or oil migration.

In standard operation, it provides non-contacting operation for positive oil ingress mitigation. If separation gas is lost, the seal maintains non-contacting operation and oil control.

In the event of a dry gas seal failure, it restricts process gas leakage during compressor shutdown at pressures up to 35 bar, while maintaining seal integrity up to 70 bar.

The Type 93AX also supports sustainability goals by reducing emissions and energy consumption. By cutting nitrogen use by up to 80%, according to test data, it lowers the demand on energy-intensive nitrogen generation systems, reducing both costs and environmental impact.

The International Energy Agency highlights that improving industrial efficiency could reduce global energy use by 12% by 2040, underscoring the significance of solutions like the Type 93AX in advancing operational and environmental objectives.

The company said that its innovations align with regional sustainability initiatives in the Middle East, such as the UAE’s Net Zero 2050 Strategy, the Make in the Emirates Initiative, and Saudi Vision 2030’s Saudi Green Initiative, which aim to reduce industrial carbon emissions by over 90% in some cases through public and private sector partnerships.

Mike Eason, Chief Technology Officer at John Crane, said, “Our customers told us they wanted a separation seal that increases safety, efficiency, and reliability. The Type 93AX delivers on these priorities.  It’s designed to keep working in real-world failure conditions to protect their most critical assets, and reduce environmental impact, while driving down OPEX and CAPEX.

“The new seal is compatible with John Crane’s dry gas seal portfolio and is supported by a global network of over 200 facilities, including manufacturing, sales, and services, and 13 global turbo service centers in more than 50 countries.  It can be sold as part of a bundled first-fit order or compressor upgrade or supplied as a stand-alone product to meet customer-specific requirements.”

More than two million Muslims flock to Mecca for the hajj.

With more than two million Muslims set to descend on Mecca for the annual hajj pilgrimage, Aramco Digital, in collaboration with the Communications, Space and Technology Commission (CST) has carried out a successful trial in crowd management using AI and specialised communications services in the Holy Sites

The trial was carried out in partnership with the Supreme Authority for Industrial Security, the Saudi Water Authority (SWA), and Saudi Arabia Railways (SAR).

The initial operational deployment of the 450 MHz mission-critical network combines AI-powered crowd management, secure communications and integrated digital infrastructure to enhance field operations and ensure a safer and more connected pilgrimage experience.

It will enable seamless, real-time voice and video communications, ensuring the quality and continuity of services provided to pilgrims while offering secure, high-efficiency connectivity with instant response, unaffected by network congestion.

The initiative reflects the network’s readiness to operate in complex, high-density environments – enabling in-depth performance analysis, real-time insight generation and faster decision-making across operations.
The system will provide real-time crowd and vehicle analytics, with instant detection of crowd density, vehicle types and movement patterns. Edge AI enables immediate recognition of safety incidents and traffic anomalies, enhancing control, reducing latency and eliminating dependence on the crowd.

By leveraging AI-powered crowd management, secure communications and integrated digital infrastructure in a complex, high density environment, the system sets a new standard in safety and efficiency and is set to enhance co-ordination for future Hajj operations.

The trials were conducted using specialised wireless communication network operating in the 450 MHz band, which was licensed to Aramco Digital in October 2024.

Eid AlHarbi, president of connectivity at Aramco Digital, commented, “The initial operational development of the mission-critical network during this year’s Hajj represented a pivotal milestone in demonstrating the network’s performance and resilience within one of the most operationally intensive and high-density environments. This step supports the broader national rollout, positioning the network as a key enabler for industrial sectors to accelerate their digital transformation in full alignment with Saudi Vision 2030.”
