Less Components and Safer Environment

The first thing the Nautic Alert solution does is re-architect the bilge configuration so nothing except a pump or hose needs to be submerged in water.  Now, when diesel, oil, or corrosive chemicals spill, the bilge is a safer environment.  Imagine, no more combining moving parts with sludge or electrical cables and connectors exposed to flammable liquids, and no more float switch to get stuck on or off.

Pump Redundancy and Trouble Detection

Primary and backup pumps are now co-located at the lowest elevation in the bilge, rather than offset elevations.  This gives the advantage of being able to automatically switch pumps without requiring an increase in water volume. By having two pumps side-by-side, Nevata can evaluate both pumps to determine if one is effective in removing water, whereas the other may not be.  If this occurs, either due to a blockage or rate of incoming water, for example, a trouble event will be detected.

Developing Leak Detection

The Nautic Alert Insight keeps track of how often pump activations occur and gives a user real-time statistics that show how frequent the pump cycles under normal conditions.  If any pump starts to cycle more frequently than nominal, a high-activity event is sent to the owner.

Pump Failure or Overcurrent Detection

Nautic Alert Nevata learns the current profile of the attached pump, and therefore, can sense when the pump is working properly, and drawing power.  It can even distinguish between a non-functioning pump, pump that’s siphoning water, and pump that’s not siphoning water.  If a pump encounters a serious issue and develops an internal short, this will be detected and the pump will immediately shutdown with periodic activation attempts to follow or will cause Nevata to switch to the other connected pump.  Likewise, if a pump fails to power on, the Nevata will switch to the other connected pump.

Pump Burn-Out Protection

Because Nevata learns the current profile of the attached pump, it knows exactly when to turn the pump off without running it dry because it can literally sense when the pump is no longer siphoning water effectively. Nevata also implores a pump watchdog feature, so that once water recedes less than 1.6 inches, the pump will be shutoff within 20 seconds no matter what.  This ensures that in no case will the pump be run continuously with marginal water in the bilge.

Continuous Runtime Detection

If switching pumps does not resolve getting the water out, and the pump is needing to run continuously to keep up with a leak, a continuous runtime event is detected and sent to the yacht owner.  If a pump is required to run continuously, it still may encounter a thermal shutdown condition where the pump disables itself momentarily to prevent overheating.  During this time, Nevata will continue to try to switch pumps to find a way to get the water out, no matter what.

Periodic Pump Testing

If a connection issue occurs over time, or if the pump simply stops working at some point in time, there are no more surprises. Nevata will automatically test the attached pumps once a week, to ensure they draw power as expected.  Because people don’t really inspect their bilge setups as recommended on a regular basis, the Nevata will do it automatically, and issue a fault if one of the pumps does not power-on properly.

Peace of Mind

Even when the Nevata is not detecting or switching pumps to work around an issue, an owner can know EXACTLY how much water is present in each bilge compartment, down to 1/10 of an inch.  No other product can do this, or any of the above, in an integrated solution.
