The AT-IV Active system is a unique product designed for diesel engine gensets in the range of 1,000 kW to 4 MW employed in mission critical installations such as hospitals, data centers, financial institutions, and drilling rigs, or for engines operating in extreme temperature applications.

The AT-IV system’s single housing assembly is modular and can be assembled in multiple configurations. It also comes complete with mounting brackets that offer extreme flexibility to meet particular installation needs. Plus, there is no need for forced inducement strategies and it offers integrated sound reductions up to 25 dB(A).

The AT-IV may be retrofitted to existing engine applications and will control pollutants (NOx, CO, VOC and PM) to permitted levels.
