Semler Industries has introduced a diesel exhaust fluid (DEF) 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 unique-modular design offers in-field expansion from 500 to 2,000 gal. to meet increasing DEF demand. The system can be integrated with any commercial, fleet, or retail dispenser currently available, and the clean, elegant design offers ideal advertising space. Semler’s Mini-Bulk is designed to ensure product integrity and can be installed in a variety of extreme climate conditions. Since 1905, Semler Industries is a leader in filtration and liquid handling products and a PEI member for more than 50 years
