DEFender™ Insulation Keeps DEF Pumps Running all Winter
Cold weather can put DEF fueling systems at risk of freezing, slowing operations and increasing service calls.
DEFender™ systems are engineered specifically for DEF equipment, not adapted from generic insulation products. The modular design allows for easy inspection, maintenance and part replacement, with individual components swapped as needed rather than replacing the entire system.
