Our OilSmart Systems incorporates pump controls and alarm sensors that differentiate between oil and water, allowing companies to responsibly discharge the water without worrying about contamination.
Custom complete systems available. From plug and play to hard wired Single Phase Simplex Panel systems.

OilSmart Pump Switch
The OilSmart Pump Switch , when combined with a non-auto sump pump, will allow water to be pumped without the risk of pumping oil. The switch is ideal for elevator sumps, transformer containment areas, parking garages, and city underground vaults.
The OilSmart™ water pump switch & sensor lets you safely pump water only! This switch energizes a pump, valve, alarm or whatever’s wired into it when it detects water, not oil. If it detects oil, it shuts the pump DOWN! It’s deadly effective and economical to use!
OilSmart Alarm System
The OilSmart Alarm System is a plug and play alarm that differentiates between oil and water. The system is complete with visible mounted indicators and dry contacts for remote monitoring. The alarm will activate with the presence of any liquid and will identify if oil or water is present. With the unique ability to differentiate between oil and water, the OilSmart Alarm System is designed as a high liquid alarm or leak detector system. The OilSmart Alarm System is triggered by the new all-in-one LiquidSmart Sensor. Alarms are equipped with both visual and audible signals. The new LiquidSmart Alarm Sensor will activate the alarm and indicator lights.
