Rypos
Diesel Particulate Filter
The California Air Resources Board has verified the Rypos DPF/Low Emission Transport Refrigeration Unit (Level 2 Plus) diesel particulate filter for use on most trailer transport refrigeration units (TRUs) using 2002 and older model year engines. The self-cleaning diesel exhaust filter uses an electrically conductive sintered metal fiber medium and electrical power from the TRU to regenerate the filter when needed. It is microprocessor controlled with a backpressure control system, an electrical control circuit, and a backpressure warning indicator.
