We would like to inform you about our recent collaboration with SAFEGAS, a brand operated by Shenzhen YuanTe Technology Co., Ltd., a Chinese manufacturer specializing in gas-detection equipment with more than 15 years of experience.

Its product portfolio includes portable and fixed gas detectors, multi-gas analyzers, disposable gas detectors, gas alarm controllers, and complete gas-monitoring systems for a wide range of marine and industrial applications.

SAFEGAS portable units are suitable for enclosed-space entry, tank inspections, cargo operations, and other routine onboard procedures, supporting the daily safety requirements of vessels.

Based on the latest regulatory requirements adopted for enclosed-space entry, vessels are required to test for carbon dioxide (CO₂), alongside oxygen (O₂), carbon monoxide (CO), LEL, and toxic gases such as hydrogen sulphide (H₂S). Therefore, five-gas detectors are required onboard instead of the four-gas detectors already in use:

• IMO Resolution MSC.581(110)
• SOLAS III/19.3.6 & XI-1/7
• RiSQ 3.2 – Q4.5 (Risk Assessment of an Enclosed Space)
• Australian port regulations

SAFEGAS offers personal and portable gas-detection units for carbon dioxide (CO₂), alongside oxygen, CO, LEL, and a wide range of toxic and hazardous gases, including H₂S, NH₃, Cl₂, SO₂, H₂, NOx, VOCs, CH₄, PH₃, and AsH₃.

SAFEGAS detectors are accompanied by ATEX/IECEx certification for hazardous-area applications, can measure from one to five gases in a single detector, and are supplied with the relevant calibration certificate.
MicMeta-T5: Multi-gas portable personal diffusion detector for the simultaneous monitoring of typical combinations such as %LEL/CH₄, O₂, H₂S, CO, and CO₂. It features audible, visual, and vibration alarms, man-down protection, and optional wireless connectivity

• Measurement range: CO: 0–1,000 ppm, H₂S: 0–100 ppm, O₂: 0–30% vol., LEL: 0–100% LEL, CO₂: 0–5% vol.
• Resolution: CO: 1 ppm, H₂S: 0.1 ppm, O₂: 0.1% vol., LEL: 1% LEL
• Alarm with sound, light, and vibration; alarm points are configurable. The man-down alarm function enhances operator safety.
• 3.7 V rechargeable lithium battery, 2,300 mAh capacity
• Real-time values, TWA, STEL, MAX, and MIN display
• IECEx: Ex ia IIC T4 Ga, Ex ia I Ma; ATEX: II 1G Ex ia IIC T4 Ga
• Standard data-logging function stores 1,000 event sets and 100,000 record sets; data can be downloaded to a PC via USB cable
• IP66/IP68 water- and dust-resistant; rugged case resistant to drops from 1.5 m
• Automatic self-test and calibration after power-on, including reset, MAX, MIN, STEL, and TWA

SKY3000-T5: Multi-gas portable personal detector with an integrated pump. The IECEx- and ATEX-certified unit is a high-performance portable gas detector capable of detecting carbon dioxide in addition to standard gases. It also features a man-down alarm.

• Principle: Electrochemical (CO, H₂S, O₂), Catalytic Combustion (LEL)
• Measurement range: CO: 0–1,000 ppm, H₂S: 0–100 ppm, O₂: 0–30% vol., LEL: 0–100% LEL, CO₂: 0–50,000 ppm
• Resolution: CO: 1 ppm, H₂S: 0.1 ppm, O₂: 0.1% vol., LEL: 1% LEL
• Alarm with sound, light, and vibration; alarm points are configurable. The man-down alarm function enhances operator safety.
• 3.7 V rechargeable lithium battery, 2,200 mAh capacity
• Real-time values, TWA, STEL, MAX, and MIN display
• IECEx: Ex ia IIC T4 Ga, Ex ia I Ma; ATEX: II 1G Ex ia IIC T4 Ga
• Standard data-logging function stores 1,000 event sets and 100,000 record sets; data can be downloaded to a PC via USB cable
• IP67 water- and dust-resistant; rugged case resistant to drops from 3 m
• Automatic self-test and calibration after power-on, including reset, MAX, MIN, STEL, and TWA

Tank-scope gas detectors for tanker vessels, equipped with IR sensors for LEL, can also be provided upon request.

An external pump, sampling probe, and relevant tube can be supplied for compliance with the regulation and included in an MSC.581(110)-compatible vessel package.

In this respect, we can provide owners and operators with the following major benefits:

• Short delivery time: maximum two weeks from order placement
• Competitive pricing for vessel detector packages
• Special discounts under fleet agreements and bulk orders
• TECHNAVA Service Station and 24/7 after-sales support
• Annual SAFE-GAS Program (ASP): optional three-year complete after-sales support under contract

We can support your esteemed company with this regulatory compliance requirement by providing suitable solutions at short notice and at competitive prices.

In urgent cases involving any of your vessels, we can mobilize a limited number of detectors from our emergency stock for immediate dispatch and support, with priority given to vessels enrolled in the Annual SAFE-GAS Program (ASP).

If no action has yet been taken to replace the existing units or arrange the initial supply onboard your vessels, we would be pleased to submit our proposal.
