A significant advancement in day-tank engineering design, ESI's iTANK® protects mission critical operations 24/7 from diesel fuel related generator failures and data center disasters.

iTANK® maximizes your data center uptime and saves you time as well as procurement and installation hassles. This unique day-tank solution offered exclusively by ESI is completely assembled and fully tested before it arrives at your site. Factory built, it is guaranteed leak-proof upon arrival.


There are numerous features, options, and benefits of the iTANK for you to consider. For example, the iTANK® includes advanced data management for your seamless compliance with all consumption reporting requirements for Federal and Local air quality permits (i.e., NOx emission reporting). Although there is far more for you to consider than provided below, the iTANK® (in general) includes:

  • Day tank sized to your facility specifications (advanced tank design with unique characteristics that protect your mission critical operations)
  • iFUEL (consumption monitoring, data reporting, network communication via Modbus, etc.)
  • RPFS (Redundant Primary Filter-Set)
  • Central Control Panel

"Easiest day tank to install . . . much easier than other day tanks." "Packaged day tank solution we've been hoping for." - Installers at NOVA mission critical facilities

"By the end of the day, we have worked out the integration and normally it takes at least a week." - Control Systems Vendor

Given the iTANK® is a fully integrated engineered system only available from ESI, please contact one of ESI's expert fuel management engineers for additional details or to schedule a demonstration. Please note the iTANK is in production at our Ashburn, Virginia factory and units are being provided to our customers at this time.
