DEF Heater – Post Style

Features



Self regulated PTC heating elements

250W @ 24V power rating

Stainless steel body

Choice of connectors and terminals

Benefits



Robust construction makes this heater well suited to

harsh environments



All raw materials used are designed for permanent

contact with DEF solution, to avoid poisoning of the

catalyst



Intrinsically safe, surface temperatures cannot reach

dangerous levels

PTC self regulates the power absorption in function of

DEF flow and temperature

Applications

General Description

To allow the SCR system to work at low temperatures,

heaters are used to maintain the DEF in liquid phase or

to thaw the solution in case of frozen DEF in the tank.



SCR systems in passenger car, commercial vehicles

or power generator

DEF tank or module



Operation

Basic Principle

When the vehicle ECU detects the risk of DEF freezing, or detects frozen DEF solution in the tank or in the module, the

DEF heater is switched on by an external relay or power switch, warming the DEF into liquidphase.

Packaging Options

Custom packaging can be provided to meet any need, please contact Littelfuse Engineering for details.
