These challenges can lead to increased maintenance, operational disruptions, and potential safety risks, especially in demanding marine environments where system performance is critical.

The challenge: ageing systems and rising costs

The TQ4400 system has been a trusted solution for years. However, over time, key components become outdated or unsupported.

Common issues include:

• Obsolete PCBs and controllers
• Increased system failures
• Difficulty sourcing spare parts
• Rising maintenance costs

For many operators, the immediate solution is a full system replacement. While effective, this approach is often:

• Cost-intensive (high CAPEX)
• Time-consuming
• Disruptive to ongoing operations

A smarter approach: electronics modernisation

At Neohance, in collaboration with TQ Environmental Ltd, we offer a more efficient alternative: TQ4400 system upgrade through electronics modernisation.

Instead of replacing the entire system, we upgrade the critical electronic components, restoring system performance while extending its operational lifetime.

This approach allows vessels to maintain continuity while improving reliability and compliance.

Key benefits of the TQ4400 upgrade

✔ Minimal downtime

Upgrades are implemented efficiently, ensuring minimal disruption to vessel operations.

✔ Lower CAPEX

Avoid the high costs associated with full system replacement.

✔ Extended system lifetime

Modernised electronics improve long-term reliability and performance.

✔ Improved reliability and compliance

Upgraded systems meet current operational and safety standards.

Designed for real-world maritime operations

Our solutions are implemented directly onboard, ensuring minimal disruption while restoring full system functionality.

This upgrade approach is specifically developed for vessels operating in demanding conditions, where uptime and reliability are essential.

A proven solution trusted by operators

Many vessels have already adopted this upgrade approach and are now operating with fully restored systems.

By focusing on practical, targeted upgrades rather than full replacements, operators can:

• Reduce costs
• Maintain operational continuity
• Improve system performance

When should you consider an upgrade?

You may benefit from a TQ4400 system upgrade if:

• Your system is no longer reliable
• Maintenance costs are increasing
• Spare parts are difficult to source
• You want to extend system life without major investment

Future-proof your gas detection system
Upgrading your TQ4400 system is a strategic step toward improving reliability, reducing costs, and ensuring long-term operational efficiency.

If your system is showing signs of ageing, a modernisation upgrade offers a practical and cost-effective solution, allowing you to maintain performance without the need for a full system replacement.

Worldwide Support & Flexible Installation
In addition to system upgrades, Neohance provides worldwide service and support to ensure seamless implementation.

Our experienced engineers can carry out installations onboard, minimizing disruption to operations. For vessels that prefer to handle installation in-house, we also offer remote guidance and technical support, enabling crews to complete the upgrade efficiently and with confidence.
