CATERPILLAR Delete Kit – DPF & DEF (SCR) Emulator
DPF and DEF (AdBlue) emulators for CATERPILLAR machines
Our offer includes the CATERPILLAR Delete Kit for effective removal of the DPF filter and DEF (SCR) emission reduction system. The emulator is designed for both CATERPILLAR machines and machines and devices equipped with the engine of this manufacturer. The electronic device designed by us simulates the operation of an efficient system, which allows for its complete shutdown. We offer emulators in two versions:
- Caterpillar DPF Delete Kit
A version of the device designed for Caterpillar DPF engines equipped only with a diesel particulate filter. - Caterpillar DEF Delete Kit
A version of the device designed for Caterpillar engines equipped with both a diesel particulate filter (DPF) and a selective catalytic reduction (SCR) system with a diesel exhaust fluid tank (DEF/AUS 32/AdBlue).
CATERPILLAR Delete Kit also works with CATERPILLAR machines that have already experienced a fault and have been limited in power/torque. The emulator pretends the correct operation of damaged elements, so their actual efficiency does not affect its proper functioning. After the repair, the system does not report errors and there is no torque limitation.
CATERPILLAR Delete Kit Installation
Installation of the emulator is non-invasive, because the device is equipped with a bundle with plugs compatible with the original. The emulator disables components and elements such as:
- urea dosing pump (AdBlue)
- DPF differential pressure sensor
- temperature sensors
- particulate filter
- NOx sensors (if any)
- NH3 sensors (if any)
Each of our emulators comes with a detailed manual that describes the step-by-step assembly process. You can also always use the support of our service technicians provided by phone or online.

The photo documentation shows the removal of the DPF filter and AdBlue in a CATERPILLAR M315D wheeled excavator equipped with a CAT® C4.4 ACERT™ engine. We also have solutions for other CATERPILLAR machines with a C4.4 engine, e.g. CAT 432F backhoe loaders. The devices allow you to turn off the diesel particulate filter DPF and the SCR (AdBlue) emission reduction system.
