Our range of Nereus gas alarms is designed for boats, such as yachts and narrow boats, but can also be installed wherever waterproof sensors and a remote warning are required. The waterproof LPG (butane/propane) and CO detectors give you sufficient warning should there be a gas leak or carbon monoxide present (different sensors) by sounding a buzzer and shining a red light on the control unit. Select a control unit with different quantities and types of sensors. The sensors can be fitted either flush or surface mounted and should ideally be located 300mm up from the floor. The sensors are interlinked by cable with the central monitoring unit.

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 buildup. Carbon monoxide has no smell or taste and is invisible to the naked eye, therefore an electronioc 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
Unique waterproof sensor - The sensors are able to survive being completely imursed allowing them to be mounted low in the bilge without the risk of water damage.
