PRODUCT SPOTLIGHT
NEXUS NANO
Use It As Your ecoSENTRY Appliance
Optima’s ecoSENTRY application monitors:
- Diesel/LPG Fuel Levels,
- GENSET Operation,
- Fuel Consumption,
- Fuel Fills & Losses,
- as well as 24/7 Tank Access.
The app also tracks AC and DC power systems, and a host of environmental sensors. It immediately relays any abnormal and out of bounds conditions. ecoSENTRY makes hidden processes in remote sites visible.
Pre-load a special version onto the NEXUS NANO to track and correlate fuel depot draws. Comparing it with tanker truck deliveries made to all your far flung sites.
This allows you to keep a sharp eye on your fuel inventory — and its timely and accurate distribution.
Pre-load the NEXUS NANO as an ecoSENTRY appliance. And it becomes our most efficient, innovative ready-to-go out of the box solution ever. We would love to demo the NEXUS NANO ecoSENTRY appliance to you.
