Product Overview
The Honeywell GASBAL™ Gas Detection System is a marine gas sampling system designed to monitor gas concentrations in enclosed spaces, including ballast tanks, void spaces and pump rooms. Widely used across different types of vessels, the system supports onboard safety by detecting potentially hazardous gas concentrations.
Although Honeywell has discontinued the GASBAL system, many installations remain in operation and continue to require maintenance, technical support and spare parts.
Neohance supports marine operators with enquiries regarding existing GASBAL installations, helping customers explore servicing, maintenance and spare parts options.
For customers considering a new installation or a complete system replacement, Honeywell also offers engineered-to-order (ETO) gas sampling solutions designed around specific operational requirements.
What is the Honeywell GASBAL System?
The GASBAL is a suction-based gas detection system developed for monitoring gas concentrations in enclosed marine spaces.
It can be installed on tankers, offshore vessels and other ships requiring gas detection in ballast tanks, dry void spaces and similar compartments.
The original system combines gas sampling, analysis and monitoring capabilities to help operators identify potentially dangerous gas concentrations and maintain safe onboard operations.
Key Features of the Original GASBAL System:
- Up to 24 suction sampling channels and 6 additional standalone inputs.
- Detection capabilities for up to 7 different gases.
- Centralised gas sampling and monitoring.
- Integrated alarm functionality.
- Local and remote monitoring capabilities.
- Modbus RTU communication for integration with other onboard systems.
Please note: The original Honeywell GASBAL system has been discontinued and is no longer offered as a new standard product.
How Does It Work?
The GASBAL system uses a suction-based sampling method to monitor gas concentrations across multiple locations onboard a vessel.
Gas samples are drawn through dedicated sampling lines and analysed by the system's gas detectors. When a measured gas concentration exceeds a predefined threshold, the system activates an alarm to notify the crew of potentially hazardous conditions.
The system also supports communication with other onboard monitoring and control equipment.
Service, Maintenance & Spare Parts
Do you have an existing Honeywell GASBAL system onboard your vessel?
Even though the original system has been discontinued, maintaining the safety and reliability of existing installations remains important.
Neohance can assist customers with enquiries related to:
- GASBAL system servicing and maintenance.
- Troubleshooting and technical support.
- Spare parts identification and availability.
- Assessment of existing installations.
- Evaluation of system modernisation or replacement options.
Our team can help you assess your existing system and identify suitable next steps based on its condition, configuration and operational requirements.
Service options and spare parts availability are subject to technical assessment and manufacturer availability.
Looking for a GASBAL Replacement?
For customers requiring a new gas sampling system, Honeywell offers an alternative approach through Engineered-to-Order (ETO) Gas Sampling Solutions.
Unlike the original GASBAL system, these solutions are not standard catalogue products. Instead, they are engineered according to the specific requirements of each customer and installation.
This approach allows the proposed system to be developed around the vessel's operational needs and technical specifications.
Neohance can assist customers in discussing their requirements and exploring the available Honeywell solutions.
Contact our team to discuss a new gas sampling system or potential GASBAL replacement.
What Problems Does It Solve?
Existing GASBAL installations may present challenges as equipment ages and the availability of original components changes.
Operators may need technical assistance to maintain their existing systems or evaluate alternative solutions when repairs are no longer practical.
Neohance helps customers explore suitable options for maintaining or replacing their gas detection equipment, supporting safe and reliable vessel operations.
Whether you require assistance with an existing GASBAL installation, spare parts identification or information about Honeywell's new gas sampling solutions, our team is available to discuss your requirements.
