CPK Automotive

What CPK Automotive does

CPK Automotive is a German developer and manufacturer of diesel engine emission control and monitoring systems, headquartered in Münster, Germany, and operating as a subsidiary of the family-owned HEINZMANN Gruppe (founded 1897, currently in its 4th generation of family ownership). The company specializes in exhaust aftertreatment technologies including diesel particulate filter (DPF) monitoring, selective catalytic reduction (SCR) dosing, and NOx recording systems, and serves both OEM manufacturers and the retrofit/aftermarket across multiple industrial verticals: buses, construction machinery, ships, locomotives, stationary generators, and mining equipment.

The core product portfolio centers on the ControlBox family of electronic control units and data loggers — variants include V.4 (general DPF monitoring), OEM (factory integration), NOx (44th BImSchV-compliant recording), and Bahn Logger (rail application) — complemented by SCR dosing systems with PT200 sensors, regeneration systems, the LiquiCat HC dosing unit, level transmitters with NBIoT connectivity, wallbox solutions, and idle control modules. With over 200,000 systems deployed globally, the company positions itself as a market leader in exhaust aftertreatment monitoring. Technology focus includes regulatory-compliance-driven features such as continuous NOx recording under the German 44th BImSchV framework, in cooperation with the VERT Association for emission reduction certification.

The business model is predominantly B2B hardware and software sales to OEM integrators and retrofit/aftermarket operators, distributed in part through the HEINZMANN Group's network of 40+ global subsidiaries and via direct sales channels. The company is led by Markus Gromer as Managing Director. Revenue mechanics, pricing models, and customer-level revenue splits are not publicly disclosed, and CPK Automotive operates as a privately held subsidiary without independent financial reporting.

Core offering

CPK Automotive develops and manufactures hardware and software systems for monitoring and controlling diesel exhaust aftertreatment, including diesel particulate filter (DPF) control units, SCR urea dosing systems, and NOx emissions data loggers. The company serves both OEM and retrofit customers in commercial vehicles, mining equipment, locomotives, marine vessels, construction machinery, and stationary engines, with more than 200,000 systems deployed globally. It operates as a subsidiary of the HEINZMANN Group.

Product overview

CPK Automotive develops and sells innovative monitoring and control systems for exhaust gas aftertreatment, primarily for diesel engines in both on-road and off-road applications. The product portfolio is organized around the DYNTEST system — a hardware and software ecosystem centered on ControlBox data loggers and the SCR dosing system. The ControlBox family includes the ControlBox V.4 (standard data logger for back pressure and temperature monitoring), ControlBox OEM (ruggedized version for mining/off-road), ControlBox NOx (intelligent data logger for NOx emissions recording per 44.BImSchV), and Bahn Logger (for rail applications). The SCR Dosing System provides Selective Catalytic Reduction for NOx reduction. Supporting products include Remote Control (SMS alarming), HC Dosing and LiquiCat® for DPF regeneration, Level Transmitter for liquid level monitoring via NBIoT, WallBox, Idle Control, and spare parts (Fuse Kit, On-Road/Off-Road Displays). The DYNTEST Analyser and CPK Terminal Software provide data transfer and evaluation capabilities. CPK Automotive serves both OEM and retrofit markets with more than 200,000 systems deployed globally, operating as a subsidiary of the HEINZMANN Group.

Products and services

• ControlBox V.4 A data logger and control unit for diesel particulate filter (DPF) monitoring and exhaust aftertreatment. It continuously records back pressure and temperature data for around 900 days, provides visual and audible alarms for filter condition, supports active regeneration control, and transfers data via the DYNTEST Analyser to a computer for evaluation.
• ControlBox OEM A ruggedized control unit (data logger) developed especially for the extreme requirements of exhaust aftertreatment for diesel engines, particularly suited for mining applications. It continuously records vehicle data and diesel particulate filter data, monitors the condition of the exhaust aftertreatment system, and alerts the driver via display or control lamps.
• ControlBox NOx An intelligent data logger for monitoring and recording NOx and O2 emissions data in compliance with the German 44th BImSchV regulation. It provides continuous recording of NOx sensor values for efficient system monitoring, with alarm messages when limit values are exceeded or system errors occur, and is engine-independent and self-contained for all engine types.
• Bahn Logger A data logger specifically designed for railway/train applications. It continuously monitors diesel locomotive exhaust aftertreatment systems and alerts in case of problems, ensuring compliance with environmental regulations and emission limits.
• SCR Dosing System A Selective Catalytic Reduction (SCR) control and dosing system for reducing NOx emissions. The SCR Control Unit DC12 injects urea water solution into the exhaust mixing section on demand using metering components (supply unit and injection nozzle). It monitors exhaust gas temperature via PT200 sensors and NOx levels via sensors before and after the catalytic converter.
• Remote Control (RemCo) Remote monitoring and control module (RemCo) for the DYNTEST system, enabling alarm signals to be sent via SMS for off-road and on-road vehicles operating in remote locations.
• HC Dosing Hydrocarbon (HC) dosing system for active regeneration of diesel particulate filters. It introduces hydrocarbons into the exhaust stream to raise temperature and burn off accumulated soot in the DPF.
• LiquiCat A catalytic liquid dosing system for DPF regeneration, providing an alternative to HC dosing for active filter regeneration in exhaust aftertreatment systems.
• Level Transmitter A level sensor for continuous level measurement of liquids, designed for measuring, recording, visualizing, and transmitting water levels at remote locations via the Internet using NBIoT cloud connectivity. Supports level profiling of lakes, rivers, or groundwater measuring points.
• WallBox A wall-mounted charging or power management unit, listed as part of CPK Automotive's product portfolio alongside other exhaust aftertreatment and monitoring products.
• Idle Control A fuel performance and idle control system for managing engine idling and fuel consumption, categorized under fuel performance systems.
