Semler Industries has introduced a Diesel Exhaust Fluid modular mini-bulk above-ground storage system for use at fleets, commercial locations and retail facilities. This Mini-Bulk is the first of its kind to meet the space restrictions of a standard fuel island and has the smallest footprint of any equal-volume system on the market, according to the company. The unit's modular design offers in-field expansion from 500 to 2000 gallons to meet increasing DEF demand. The system can be integrated with any commercial, fleet, or retail dispenser currently available, and the design offers advertising space. Semler's Mini-Bulk can be installed in a variety of extreme climate conditions.
