EXHAUST ALERT SYSTEM

Why fit a Halyard Exhaust Alert?

Marine diesel exhaust systems are designed to take temperatures of only 120°C. The exhaust gases, however, may reach more than 500°C. To cool the gases, the exhaust depends on a free flow of cooling water from the engine. This flow can be cut off, by a plastic bag or seaweed being sucked into the intake, or by a problem with the water pump. The exhaust temperature will rise immediately to around 450°C, the exhaust will overheat and may be seriously damaged. In most situations Exhaust Alert will warn you before serious damage occurs.

What makes Exhaust Alert so different?

An exhaust temperature alarm system must measure temperature inside the exhaust system to be effective. Sensors fitted on the outside of the exhaust cannot respond quickly as they must wait for the heat to work through the hose to reach the sensor.
