01
All-stainless circulation loop
An onboard pump circulates DEF from the tank through the heating element or heat exchanger and back — 304 stainless throughout for long-term reliability.

Select a model to see where it fits in the family. Every class shares the same filtration, controls, and enclosure — only the flow rate changes.
UM3
Circulation Heater3–10 GPM (12–40 LPM)
A circulation heater that maintains DEF urea temperature in storage tanks and piping to avoid service interruption from freezing. An onboard pump circulates DEF through a heating element for safe, reliable heating of steel or plastic tanks, in all-stainless construction for long-term reliability.

Built for DEF quality
Keep DEF in range, in any climate.
Freeze protection (cold climates)
The UM3 heater keeps DEF above freezing in tanks and piping so SCR service is never interrupted by frozen fluid.
Quality protection (warm climates)
The UM3C chiller holds DEF cool to prevent quality degradation from high ambient storage temperatures.
Steel or plastic tanks & piping
Circulation conditioning works with either tank material, adding safe, even temperature control without internal elements.
Comprehensive monitoring
Over-temp safety sensors and remote BMS/SCADA integration give full visibility into DEF condition and system status.
