NEW: SCR-Smartline AL

Fischer Abgastechnik is the go-to specialist for exhaust after-treatment systems. The company – which is based in Emsdetten (Germany) and has an in-house development and design department for open and closed-loop controls and CFD calculations – has just developed and launched a new cost-effective SCR system named modular SCR-Smartline AL system. This product complements the company’s already well-established SCR-HD (heavy duty) and SCR-Industry systems. Proprietary open and closed-loop control units are combined with validated components from the automotive sector to produce a perfectly rounded, all-in-one system. Its modular concept sets it apart, and the system can be used on its own to dispense aqueous urea solution at a rate of up to 10 kg/h. When combined with the Fischer BOC catalysts, which were introduced over 10 years ago, it can reliably ensure complete compliance with all limits values of the 44th Ordinance for the Implementation of the German Federal Immission Control Act (BISchV). The Fischer engineers are specialists in bespoke and retrofit solutions.

 

SCR-Smartline AL (Air Less)

The permanently tightening requirements concerning efficient and effective exhaust gas aftertreatment systems – in particular regarding NOx-reduction measures - require cost-efficient and reliable urea dosing systems. Its compactness and the use of series-production-approved components make the SCR-Smartline AL system an adequate alternative to the already well-proven SCR-Smartline and SCR-HD systems from Fischer. Based on NOx-sensors before and after the SCR catalyst and the exhaust gas mass flow, the SCR-Smartline AL system calculates the precise real-time demand of the reducing agent which is then injected into the exhaust gas by the pump module and doser unit. Additional temperature sensors are used to monitor the catalyst temperature and ensure, it is used in its optimal operating range. This dosing strategy leads to an ideal NOx-reduction and minimized ammonia slip.

The advantages of the SCR-Smartline AL:

  • Compressed air-free, no compressor required
  • System voltage 24 volts
  • High validated OEM product
  • Wide range of applications for engines from 100 kW up to 1.000 kW
