Designed for ease of use in marine, offshore, and safety-critical environments, each cylinder provides a consistent, high-quality gas supply in a compact, practical format. Lightweight, durable, and manufactured to exacting standards, our portable cylinders support precise readings, dependable performance and confidence in the field.
Scrubber Gases
(EGCS)
Specialist gas solutions for the marine and industrial sectors.
Scrubber gases are used to ensure accurate calibration of emissions-monitoring equipment in exhaust gas cleaning systems. For vessels operating under IMO 2020 requirements, reliable calibration is essential for monitoring sulphur oxide emissions and helping ensure EGCS systems continue to perform effectively.
Marine Gas Supplies provides specialist scrubber gas solutions for marine and offshore applications, supporting vessel operators with dependable supply, technical knowledge, and products suited ot safety-critical environments.
Our 10L cylinders are available for shipping in most cases, helping vessels maintain the stock required to support compliance, operational readiness, and accurate emissions monitoring at sea.
Supply Logistics: We offer flexible delivery options, including direct vessel supply and bulk tanker shipments, tailored to your specific marine logistics requirements.
Gas Detection Tubes
Gastec tubes provide a fast, portable and reliable method for detecting and measuring gases across marine, offshore, industrial, and environmental applications.
Designed for ease of use, each tube contains a specialist reagent that reacts with a specific target gas. When air is drawn through the tube using a compatible sampling pump, the reagent changes colour, giving a clear visual indication of gas concentration levels.
This simple and effective testing method allows users to carry out on-the-spot gas analysis without the need for complex equipment. Compact, accurate, and cost-effective, Gastec tubes are widely used for safety checks, environmental monitoring, quality control and confined space assessments.
Regulators & Equipment
Marine Gas Supplies provides a reliable range of regulators and specialist equipment designed to support accurate gas delivery, controlled flow and dependable performance across marine, offshore, and industrial applications.
Demand and Fixed Flow Regulators for C-10 Cylinders
Our C-10 cylinders are compatible with both demand and flow regulators and fixed flow regulators, offering flexibility across a range of calibration and gas detection requirements.
Both options are built for precision, durability, and seamless integration with our C-10 cylinders.
High-Pressure Regulators
Demand Flow Regulators
Demand flow regulators are designed for use with compatible gas detection instruments, delivering gas only when the instrument requires it. This on-demand supply helps improve gas efficiency by reducing unnecessary flow, limiting waste and extending the usable life of the cylinder.
By responding directly to the instrument's demand, these regulators provide a controlled and efficient method of gas delivery for calibration and testing applications.
Fixed Flow Regulators
Fixed flow regulators are designed to provide a constant, pre-set gas flow rate, making them a reliable choice for calibration and other controlled gas delivery applications. By maintaining a steady output, they help ensure consistent gas flow throughout the testing or calibration process.
These regulators are particularly useful where accuracy, repeatability, and stable delivery are required. Their simple, dependable operation makes the suitable for a wide range of marin, offshore, and industrial environments.
Single-Stage HP Regulators
We also supply high-pressure regulators in both single-stage and dual stage configurations, supporting applications that require reliable pressure control and consistent gas delivery.
Single-stage high-pressure regulators are designed for applications requiring direct and efficient pressure control. They reduce cylinder pressure to a usable outlet pressure in one stage, making them a practical solution for straightforward gas delivery requirements.
Their simple and robust design makes them well suited to a range of marine, offshore and industrial applications where reliability, ease of use, and consistent performance are essential. Built for durability and efficient operation, they provide a reliable option for users who need a straightforward high-pressure regulation solution.
Dual-Stage HP Regulators
Dual-stage high-pressure regulators provide enhanced pressure stability, helping maintain a steady output even as cylinder pressure decreases. This makes them ideal for more sensitive applications where long-term accuracy and control are required.
By reducing pressure in two stages, these regulators offer greater consistency and precision throughout use. They are particularly suited to applications where stable delivery is critical, supporting reliable performance across marine, offshore, and industrial environments where accuracy and safety are essential.
MGS Legionella Testing Range
Rapid Legionella Testing for Safer Marine and Offshore Operations
The MGS Legionella Testing Range provides fast, reliable and easy-to-use on-site testing solutions for marine, offshore, and industrial water systems.
Designed to support vessel operators, shipowners, offshore teams, and compliance managers, our testing range helps identify potential Legionella risk quickly, without waiting days or weeks for laboratory results. With clear results available in just 25 minutes, the MGS range gives teams the information they need to act quickly, protect crew health and support safer onboard water management.
Whether you need focused testing for Legionella Pneumophila serogroup 1, or broader detection across serogroups 1-15, Marine Gas Supplies can supply the right resting solution for your vessel, site, or operation.
Why Legionella Testing Matters at Sea
Legionella can present a serious risk wherever water systems are present, particularly in enclosed, high-use, or remote environments. On vessels and offshore sites, water systems can be exposed to complex conditions, limited access to laboratory testing and strict operational demands.
Fast on-site testing helps teams make informed decisions without unnecessary delays. This is especially important for vessels, offshore assets, and remote operations where sending samples away for laboratory culture can take time and may delay critical action.
The MGS Legionella Testing Range is designed to support:
-
Crew Health and Safety
-
Marine Water System Management
-
Offshore and Vessel Compliance Procedures
-
Faster Decision-Making
-
Reduced Reliance on Delayed Laboratory Results
-
Improved Visibility of Onboard Water Risks
