Nereus LPG and Carbon Monoxide Gas Boat Alarms

Detect Gas in the Bilge

LPG (butane/propane) is used extensively on boats to provide fuel for cooking and heating. Being heavier than air, any leak of gas will sink and can collect in the boat from the bilge upwards. A naked flame or a spark from an engine or switch is all that is required to cause an explosion.

Carbon Monoxide (CO) is the poisonous gas formed when fuels such as LPG, petrol, or charcoal are burnt. A faulty appliance or adverse weather conditions can quickly result in a dangerous build-up. Carbon monoxide has no smell or taste and is invisible to the naked eye, therefore an electronic sensor is the only reliable way to warn or this potentially fatal gas build up.

The Usual Problem – Water Damaged Sensors

The problem is where to site the sensors. A sensor mounted anywhere in the bilge is prone to water damage. This is especially the case, when mounted low in the bilge, ie where it needs to be fitted. Once wet, traditional sensors are permanently damaged and can give a continuous false alarms. This leaves the crew unsure how to act, not knowing, whether the alarm is due to a gas leak or damaged sensor. Apart from the inconvenience, this results in expensive repair and a period without protection.

The Solution – Unique Waterproof Sensor

Nereus LPG and CO sensors are able to survive being completely immersed, allowing them to be mounted low in the bilge without the risk of water damage.
