Additional Information
The limit values expected for the future will be so low that after treatment systems will have to undertake additional measures to reduce the NOx emissions of vehicles in the period immediately after cold starting. Typical cold start times of commercial vehicles are between five and ten minutes, after which time the SCR system has warmed up to the point where it provides excellent NOx conversion.
In order to obtain favourable conditions for its SCR systems during cold starts, HJS has developed an electric heater. The core element of this device, the heating conductor, is electrically decoupled from the housing by means of insulators. During a cold start, the heating conductor is powered by the on-board electrical system and heats the exhaust mass flow. Depending on the setup, temperatures of around 1000°C can be reached in the heater, enabling downstream components of the aftertreatment system to be quickly brought up to operating temperature.
The key features at a glance
- Diameter: from 4.66” up to 13”
- Not dependent on the catalyst substrate
- Extremely low backpressure
- Output: 5 – 20 kW @ 12/24/48 V
- Heating rate of up to 50 K/s
Benefits
1. Faster Exhaust Aftertreatment Activation
-
Ensures catalytic converters reach optimal operating temperature (200°C+) quickly, even during cold starts.
-
Reduces cold-phase emissions, critical for meeting Euro VII and future standards.
2. Improved Emissions Compliance
-
Minimizes harmful pollutants (NOx, CO, HC) during low-temperature operation.
-
Helps vehicles pass strict emissions tests (RDE, WLTP) by maintaining efficient aftertreatment.
3. Energy-Efficient Heating
-
Uses the vehicle’s electrical system to generate heat, avoiding extra fuel consumption.
-
Precise temperature control avoids overheating or wasted energy.
4. Compact & Lightweight Design
-
Easy integration into existing exhaust systems without major modifications.
-
Durable construction for long-term reliability in harsh conditions.
5. Future-Proof Solution
-
Prepares fleets for upcoming regulations (Euro VII, China 6, U.S. EPA standards).
-
Adaptable for hybrids and EVs, where exhaust heat may be insufficient.
6. Reduced Risk of Catalyst Damage
- Prevents sulfur poisoning and soot buildup in SCR/DPF systems by maintaining optimal temps.
