Crowcon recently announced that the Swedish Coastguard service has selected the flameproof (Exd) infra-red Nimbus fixed gas detector and Gasmaster control panel for one of its newly constructed hovercraft.
The vessel will carry two Ski-Doo snowmobiles in the cargo bay, which will be used for emergency rescue services during the winter months. Because of the danger of petrol vapour leaking from the snowmobiles, the bay had to be fitted with a reliable hydrocarbon gas detector and control panel.
If the Nimbus detector registers dangerous levels of petrol vapour, says Crowcon, ventilation and alarm systems are automatically triggered by the Gasmaster control panel. In addition, a local external status light will show if the unit is in normal function, or in fault.
The rugged detector is designed to operate in the dirtiest, harshest conditions, adds the company. The optics will operate at up to 90-per-cent obscuration; at 75-per-cent obscuration a warning appears on the control panel, informing operators that the optics need cleaning. Crowcon says the Nimbus is simple to use, even in inaccessible areas. A duct mounting plate is available, incorporating a remote gassing port, which allows calibration checking without requiring entry into the duct.
